This looks like an LLVM bug to me, but might be helpful if someone could confirm it isn't a misunderstanding in our use of attributes. There seems to be a null pointer dereference happening here since SimplifyCFGPass hoisted too many loads over this branch. Before SimplifyCFGPass After SimplifyCFGPass |

Here's a manual reduction.

* Improve type-stability in SymTridiagonal triu!/tril! (#55646)
Changing the final `elseif` branch to an `else` makes it clear that the
method definite returns a value, and the returned type is now a
`Tridiagonal` instead of a `Union{Nothing, Tridiagonal}`
* Reuse size-check function from `lacpy!` in `copytrito!` (#55664)
Since there is a size-check function in `lacpy!` that does the same
thing, we may reuse it instead of duplicating the check
* Update calling-c-and-fortran-code.md: fix ccall parameters (not a tuple) (#55665)
* Allow exact redefinition for types with recursive supertype reference (#55380)
This PR allows redefining a type when the new type is exactly identical
to the previous one (like #17618, #20592 and #21024), even if the type
has a reference to itself in its supertype. That particular case used to
error (issue #54757), whereas with this PR:

- [ ] ~Maybe drop the `@` prefix when coloring it, given it's obviously

* better signal handling (#55623)
Instead of relying on creating a fake stack frame, and having no signals
delivered, kernel bugs, accidentally gc_collect, or other issues occur
during the delivery and execution of these calls, use the ability we
added recently to emulate a longjmp into a unw_context to eliminate any
time where there would exist any invalid states.
Secondly, when calling jl_exit_thread0_cb, we used to end up completely
smashing the unwind info (with CFI_NOUNWIND), but this makes core files
from SIGQUIT much less helpful, so we now have a `fake_stack_pop`
function with contains the necessary CFI directives such that a minimal
unwind from the debugger will likely still succeed up into the frames
that were removed. We cannot do this perfectly on AArch64 since that
platform's DWARF spec lacks the ability to do so. On other platforms,
this should be possible to implement exactly (subject to libunwind
implementation quality). This is currently thus only fully implemented for
x86_64 on Darwin Apple.

The error pattern mentioned in

So it seems more robust to check the bounds in env directly.
The equivalent typevar propagation is lifted from `subtype_var` for the
same reason.
* Adding `JL_DATA_TYPE` annotation to `_jl_globalref_t` (#55684)

* Make `rename` public (#55652)
Fixes #41584. Follow up of #55503
I think `rename` is a very useful low-level file system operation. Many
other programming languages have this function, so it is useful when
porting IO code to Julia.
One use case is to improve the Zarr.jl package to be more compatible
with zarr-python.
https://github.com/zarr-developers/zarr-python/blob/0b5483a7958e2ae5512a14eb424a84b2a75dd727/src/zarr/v2/storage.py#L994
uses the `os.replace` function. It would be nice to be able to directly
use `Base.rename` as a replacement for `os.replace` to ensure
compatibility.
Another use case is writing a safe zip file extractor in pure Julia.
https://github.com/madler/sunzip/blob/34107fa9e2a2e36e7e72725dc4c58c9ad6179898/sunzip.c#L365
uses the `rename` function to do this in C.
Lastly in
https://github.com/medyan-dev/MEDYANSimRunner.jl/blob/67d5b42cc599670486d5d640260a95e951091f7a/src/file-saving.jl#L83
I am using `ccall(:jl_fs_rename` to save files, because I have large
numbers of Julia processes creating and reading these files at the same
time on a distributed file system on a cluster, so I don't want data to
become corrupted if one of the nodes crashes (which happens fairly
regularly). However `jl_fs_rename` is not public, and might break in a
future release.
This PR also adds a note to `mv` comparing it to the `mv` command,
similar to the note on the `cp` function.

* Canonicalize names of nested functions by keeping a more fine grained counter -- per (module, method name) pair (#53719)
As mentioned in https://github.com/JuliaLang/julia/pull/53716, we've
been noticing that `precompile` statements lists from one version of our
codebase often don't apply cleanly in a slightly different version.
That's because a lot of nested and anonymous function names have a
global numeric suffix which is incremented every time a new name is
generated, and these numeric suffixes are not very stable across
codebase changes.
To solve this, this PR makes the numeric suffixes a bit more fine
grained: every pair of (module, top-level/outermost function name) will
have its own counter, which should make nested function names a bit more
stable across different versions.
This PR applies @JeffBezanson's idea of making the symbol name changes
directly in `current-julia-module-counter`.
Here is an example:
```Julia
julia> function foo(x)
function bar(y)
return x + y
end
end
foo (generic function with 1 method)
julia> f = foo(42)
(::var"#bar#foo##0"{Int64}) (generic function with 1 method)
```

etc.).

* Fix various issues with PGO+LTO makefile (#55581)
This fixes various issues with the PGO+LTO makefile

https://github.com/JuliaLang/julia/blob/eb5587dac02d1f6edf486a71b95149139cc5d9f7/Make.inc#L734
This is because setting `CC` and `CCX` by passing them as arguments to
`make` prevents `Make.inc` from prepending these variables with `ccache`
as `Make.inc` doesn't use override. To workaround this I instead set
`USECLANG` and add the toolchain to the `PATH`.
- To deal with similar issues for the other make flags, I pass them as
environment variables which can be edited in `Make.inc`.
- I add a way to build in one go by creating the `all` target, now you
can just run `make` and a PGO+LTO build that profiles Julia's build will
be generated.
- I workaround `PROFRAW_FILES` not being reevaluated after `stage1`
builds, this caused the generation of `PROFILE_FILE` to run an outdated
command if `stage1` was built and affected the profraw files. This is
important when building in one go.
- I add a way to run rules like `binary-dist` which are not defined in
this makefile with the correct toolchain which for example prevents
`make binary-dist` from unnecessarily rebuilding `sys.ji`.
- Include `-Wl,--undefined-version` till
https://github.com/JuliaLang/julia/issues/54533 gets fixed.
These changes need to be copied to the PGO+LTO+BOLT makefile and some to
the BOLT makefile in a later pr.

* Avoid materializing arrays in bidiag matmul (#55450)
Currently, small `Bidiagonal`/`Tridiagonal` matrices are materialized in
matrix multiplications, but this is wasteful and unnecessary. This PR
changes this to use a naive matrix multiplication for small matrices,
and fall back to the banded multiplication for larger ones.
Multiplication by a `Bidiagonal` falls back to a banded matrix
multiplication for all sizes in the current implementation, and iterates
in a cache-friendly manner for the non-`Bidiagonal` matrix.
In certain cases, the matrices were being materialized if the
non-structured matrix was small, even if the structured matrix was
large. This is changed as well in this PR.
Some improvements in performance:
```julia
julia> B = Bidiagonal(rand(3), rand(2), :U); A = rand(size(B)...); C = similar(A);
julia> @btime mul!($C, $A, $B);

* Various fixes to byte / bytearray search (#54579)
This was originally intended as a targeted fix to #54578, but I ran into
a bunch of smaller issues with this code that also needed to be solved
and it turned out to be difficult to fix them with small, trivial PRs.
I would also like to refactor this whole file, but I want these
correctness fixes to be merged first, because a larger refactoring has
higher risk of getting stuck without getting reviewed and merged.
## Larger things that needs decisions
* The internal union `Base.ByteArray` has been deleted. Instead, the
unions `DenseInt8` and `DenseUInt8` have been added. These more
comprehensively cover the types that was meant, e.g. `Memory{UInt8}` was
incorrectly not covered by the former. As stated in the TODO, the
concept of a "memory backed dense byte array" is needed throughout
Julia, so this ideally needs to be implemented as a single type and used
throughout Base. The fix here is a decent temporary solution. See #53178
#54581
* The `findall` docstring between two arrays was incorrectly not
attached to the method - now it is. **Note that this change _changes_
the documentation** since it includes a docstring that was previously
missed. Hence, it's an API addition.
* Added a new minimal `testhelpers/OffsetDenseArrays.jl` which provide a
`DenseVector` with offset axes for testing purposes.
## Trivial fixes
* `findfirst(==(Int8(-1)), [0xff])` and similar findlast, findnext and
findprev is no longer buggy, see #54578
* `findfirst([0x0ff], Int8[-1])` is similarly no longer buggy, see
#54578
* `findnext(==('\xa6'), "æ", 1)` and `findprev(==('\xa6'), "æa", 2)` no
longer incorrectly throws an error
* The byte-oriented find* functions now work correctly with offset
arrays
* Fixed incorrect use of `GC.@preserve`, where the pointer was taken
before the preserve block.
* More of the optimised string methods now also apply to
`SubString{String}`

* codegen: some cleanup of layout computations (#55730)
Change Alloca to take an explicit alignment, rather than relying on LLVM
to guess our intended alignment from the DataLayout.
Eventually we should try to change this code to just get all layout data
from julia queries (jl_field_offset, julia_alignment, etc.) instead of
relying on creating an LLVM element type for memory and inspecting it
(CountTrackedPointers, DataLayout, and so on).

* Update stable version number in readme to v1.10.5 (#55742)
* Add `invokelatest` barrier to `string(...)` in `@assert` (#55739)
This change protects `@assert` from invalidations to `Base.string(...)`
by adding an `invokelatest` barrier.
A common source of invalidations right now is `print(io,
join(args...))`. The problem is:
1. Inference concludes that `join(::Any...)` returns
`Union{String,AnnotatedString}`
2. The `print` call is union-split to `String` and `AnnotatedString`
3. This code is now invalidated when StyledStrings defines `print(io,
::AnnotatedString)`
The invalidation chain for `@assert` is similar: ` @assert 1 == 1` calls
into `string(::Expr)` which calls into `print(io, join(args::Any...))`.
Unfortunately that leads to the invalidation of almost all `@assert`s
without an explicit error message

* Broadcast binary ops involving strided triangular (#55798)
Currently, we evaluate expressions like `(A::UpperTriangular) +
(B::UpperTriangular)` using broadcasting if both `A` and `B` have
strided parents, and forward the summation to the parents otherwise.
This PR changes this to use broadcasting if either of the two has a
strided parent. This avoids accessing the parent corresponding to the
structural zero elements, as the index might not be initialized.
Fixes https://github.com/JuliaLang/julia/issues/55590
This isn't a general fix, as we still sum the parents if neither is
strided. However, it will address common cases.
This also improves performance, as we only need to loop over one half:
```julia
julia> using LinearAlgebra
julia> U = UpperTriangular(zeros(100,100));
julia> B = Bidiagonal(zeros(100), zeros(99), :U);
julia> @btime $U + $B;

This relands #55450 and adds tests for the failing case noted in
https://github.com/JuliaLang/julia/issues/55727. The `addmul` tests that
were failing earlier pass with this change.
The issue in the earlier PR was that we were not exiting quickly for
`iszero(alpha)` in `_bibimul!` for small matrices, and were computing
the result as `C .= A * B * alpha + C * beta`. The problem with this is
that if `A * B` contains `NaN`s, this propagates to `C` even if `alpha
=== 0.0`. This is fixed now, and the result is only computed if
`!iszero(alpha)`.

With this, certain indexing operations involving a `BandIndex` may be

```julia
julia> n = 3; T = Tridiagonal(rand(n-1), rand(n), rand(n-1));
julia> @code_warntype ((T,j) -> UpperTriangular(T)[LinearAlgebra.BandIndex(2,j)])(T, 1)

│ %4 = Base.getindex(%1, %3)::Core.Const(0.0)

```
The indexing operation may be evaluated at compile-time, as the band
index is constant-propagated.

* Add filesystem func to transform a path to a URI (#55454)
In a few places across Base and the stdlib, we emit paths that we like
people to be able to click on in their terminal and editor. Up to this
point, we have relied on auto-filepath detection, but this does not
allow for alternative link text, such as contracted paths.
Doing so (via OSC 8 terminal links for example) requires filepath URI
encoding.
This functionality was previously part of a PR modifying stacktrace
printing (#51816), but after that became held up for unrelated reasons
and another PR appeared that would benefit from this utility (#55335),
I've split out this functionality so it can be used before the
stacktrace printing PR is resolved.
* constrain the path argument of `include` functions to `AbstractString` (#55466)
Each `Module` defined with `module` automatically gets an `include`
function with two methods. Each of those two methods takes a file path
as its last argument. Even though the path argument is unconstrained by
dispatch, it's documented as constrained with `::AbstractString`:
https://docs.julialang.org/en/v1.11-dev/base/base/#include
Furthermore, I think that any invocation of `include` with a
non-`AbstractString` path will necessarily throw a `MethodError`
eventually. Thus this change should be harmless.
Adding the type constraint to the path argument is an improvement
because any possible exception would be thrown earlier than before.
Apart from modules defined with `module`, the same issue is present with
the anonymous modules created by `evalfile`, which is also addressed.
Sidenote: `evalfile` seems to be completely untested apart from the test
added here.

* codegen: split gc roots from other bits on stack (#55767)
In order to help avoid memory provenance issues, and better utilize
stack space (somewhat), and use FCA less, change the preferred
representation of an immutable object to be a pair of
`<packed-data,roots>` values. This packing requires some care at the
boundaries and if the expected field alignment exceeds that of a
pointer. The change is expected to eventually make codegen more flexible
at representing unions of values with both bits and pointer regions.
Eventually we can also have someone improve the late-gc-lowering pass to
take advantage of this increased information accuracy, but currently it
will not be any better than before at laying out the frame.

* inference: add missing `TypeVar` handling for `instanceof_tfunc` (#55884)
I thought these sort of problems had been addressed by d60f92c, but it
seems some were missed. Specifically, `t.a` and `t.b` from `t::Union`
could be `TypeVar`, and if they are passed to a subroutine or recursed
without being unwrapped or rewrapped, errors like JuliaLang/julia#55882
could occur.
This commit resolves the issue by calling `unwraptv` in the `Union`
handling within `instanceof_tfunc`. I also found a similar issue inside
`nfields_tfunc`, so that has also been fixed, and test cases have been
added. While I haven't been able to make up a test case specifically for
the fix in `instanceof_tfunc`, I have confirmed that this commit
certainly fixes the issue reported in JuliaLang/julia#55882.

This adds a command line option `--trim` that builds images where code
is only included if it is statically reachable from methods marked using
the new function `entrypoint`. Compile-time errors are given for call
sites that are too dynamic to allow trimming the call graph (however
there is an `unsafe` option if you want to try building anyway to see
what happens).
The PR has two other components. One is changes to Base that generally
allow more code to be compiled in this mode. These changes will either
be merged in separate PRs or moved to a separate part of the workflow
(where we will build a custom system image for this purpose). The branch
is set up this way to make it easy to check out and try the
functionality.
The other component is everything in the `juliac/` directory, which
implements a compiler driver script based on this new option, along with
some examples and tests. This will eventually become a package "app"
that depends on PackageCompiler and provides a CLI for all of this
stuff, so it will not be merged here. To try an example:
```
julia contrib/juliac.jl --output-exe hello --trim test/trimming/hello.jl
```
When stripped the resulting executable is currently about 900kb on my
machine.

* prevent loading other extensions when precompiling an extension (#55589)
The current way of loading extensions when precompiling an extension
very easily leads to cycles. For example, if you have more than one
extension and you happen to transitively depend on the triggers of one
of your extensions you will immediately hit a cycle where the extensions
will try to load each other indefinitely. This is an issue because you
cannot directly influence your transitive dependency graph so from this
p.o.v the current system of loading extension is "unsound".
The test added here checks this scenario and we can now precompile and
load it without any warnings or issues.
Would have made https://github.com/JuliaLang/julia/issues/55517 a non
issue.

* TOML: Avoid type-pirating `Base.TOML.Parser` (#55892)
Since stdlibs can be duplicated but Base never is, `Base.require_stdlib`
makes type piracy even more complicated than it normally would be.
To adapt, this changes `TOML.Parser` to be a type defined by the TOML
stdlib, so that we can define methods on it without committing
type-piracy and avoid problems like Pkg.jl#4017
Resolves

* [FileWatching] fix PollingFileWatcher design and add workaround for a stat bug
What started as an innocent fix for a stat bug on Apple (#48667) turned
into a full blown investigation into the design problems with the libuv
backend for PollingFileWatcher, and writing my own implementation of it
instead which could avoid those singled-threaded concurrency bugs.
* [FileWatching] fix FileMonitor similarly and improve pidfile reliability
Previously pidfile used the same poll_interval as sleep to detect if
this code made any concurrency mistakes, but we do not really need to do
that once FileMonitor is fixed to be reliable in the presence of
parallel concurrency (instead of using watch_file).
* [FileWatching] reorganize file and add docs
* Add `--trace-dispatch` (#55848)
* relocation: account for trailing path separator in depot paths (#55355)
Fixes #55340
* change compiler to be stackless (#55575)
This change ensures the compiler uses very little stack, making it
compatible with running on any arbitrary system stack size and depths
much more reliably. It also could be further modified now to easily add
various forms of pause-able/resumable inference, since there is no
implicit state on the stack--everything is local and explicit now.
Whereas before, less than 900 frames would crash in less than a second:
```
$ time ./julia -e 'f(::Val{N}) where {N} = N <= 0 ? 0 : f(Val(N - 1)); f(Val(1000))'
Warning: detected a stack overflow; program state may be corrupted, so further execution might be unreliable.
Internal error: during type inference of
f(Base.Val{1000})
Encountered stack overflow.
This might be caused by recursion over very long tuples or argument lists.

* optimizer: simplify the finalizer inlining pass a bit (#55934)
Minor adjustments have been made to the algorithm of the finalizer
inlining pass. Previously, it required that the finalizer registration
dominate all uses, but this is not always necessary as far as the
finalizer inlining point dominates all the uses. So the check has been
relaxed. Other minor fixes have been made as well, but their importance
is low.
* Limit `@inbounds` to indexing in the dual-iterator branch in `copyto_unaliased!` (#55919)
This simplifies the `copyto_unalised!` implementation where the source
and destination have different `IndexStyle`s, and limits the `@inbounds`
to only the indexing operation. In particular, the iteration over
`eachindex(dest)` is not marked as `@inbounds` anymore. This seems to
help with performance when the destination uses Cartesian indexing.
Reduced implementation of the branch:
```julia
function copyto_proposed!(dest, src)
axes(dest) == axes(src) || throw(ArgumentError("incompatible sizes"))
iterdest, itersrc = eachindex(dest), eachindex(src)
for (destind, srcind) in zip(iterdest, itersrc)
@inbounds dest[destind] = src[srcind]
end
dest
end
function copyto_current!(dest, src)
axes(dest) == axes(src) || throw(ArgumentError("incompatible sizes"))
iterdest, itersrc = eachindex(dest), eachindex(src)
ret = iterate(iterdest)
@inbounds for a in src
idx, state = ret::NTuple{2,Any}
dest[idx] = a
ret = iterate(iterdest, state)
end
dest
end
function copyto_current_limitinbounds!(dest, src)
axes(dest) == axes(src) || throw(ArgumentError("incompatible sizes"))
iterdest, itersrc = eachindex(dest), eachindex(src)
ret = iterate(iterdest)
for isrc in itersrc
idx, state = ret::NTuple{2,Any}
@inbounds dest[idx] = src[isrc]
ret = iterate(iterdest, state)
end
dest
end
```

Build Info:
Official https://julialang.org release
Platform Info:
OS: Linux (x86_64-linux-gnu)

```
I'm not quite certain why the proposed implementation here
(`copyto_proposed!`) is even faster than
`copyto_current_limitinbounds!`. In any case, `copyto_proposed!` is
easier to read, so I'm not complaining.
This fixes https://github.com/JuliaLang/julia/issues/53158
* Strong zero in Diagonal triple multiplication (#55927)
Currently, triple multiplication with a `LinearAlgebra.BandedMatrix`
sandwiched between two `Diagonal`s isn't associative, as this is
implemented using broadcasting, which doesn't assume a strong zero,
whereas the two-term matrix multiplication does.
```julia
julia> D = Diagonal(StepRangeLen(NaN, 0, 3));
julia> B = Bidiagonal(1:3, 1:2, :U);
julia> D * B * D
3×3 Matrix{Float64}:
NaN NaN NaN
NaN NaN NaN
NaN NaN NaN
julia> (D * B) * D
3×3 Bidiagonal{Float64, Vector{Float64}}:
NaN NaN ⋅
⋅ NaN NaN
⋅ ⋅ NaN
julia> D * (B * D)
3×3 Bidiagonal{Float64, Vector{Float64}}:
NaN NaN ⋅
⋅ NaN NaN
⋅ ⋅ NaN
```
This PR ensures that the 3-term multiplication is evaluated as a
sequence of two-term multiplications, which fixes this issue. This also
improves performance, as only the bands need to be evaluated now.
```julia
julia> D = Diagonal(1:1000); B = Bidiagonal(1:1000, 1:999, :U);
julia> @btime $D * $B * $D;
656.364 μs (11 allocations: 7.63 MiB) # v"1.12.0-DEV.1262"

```
* Fix dispatch on `alg` in Float16 Hermitian eigen (#55928)
Currently,
```julia
julia> using LinearAlgebra
julia> A = Hermitian(reshape(Float16[1:16;], 4, 4));
julia> eigen(A).values |> typeof
Vector{Float16} (alias for Array{Float16, 1})
julia> eigen(A, LinearAlgebra.QRIteration()).values |> typeof
Vector{Float32} (alias for Array{Float32, 1})
```
This PR moves the specialization on the `eltype` to an internal method,
so that firstly all `alg`s dispatch to that method, and secondly, there
are no ambiguities introduce by specializing the top-level `eigen`. The
latter currently causes test failures in `StaticArrays`
(https://github.com/JuliaArrays/StaticArrays.jl/actions/runs/11092206012/job/30816955210?pr=1279),
and should be fixed by this PR.
* Remove specialized `ishermitian` method for `Diagonal{<:Real}` (#55948)
The fallback method for `Diagonal{<:Number}` handles this already by
checking that the `diag` is real, so we don't need this additional
specialization.
* Fix logic in `?` docstring example (#55945)
* fix `unwrap_macrocalls` (#55950)
The implementation of `unwrap_macrocalls` has assumed that what
`:macrocall` wraps is always an `Expr` object, but that is not
necessarily correct:
```julia
julia> Base.@assume_effects :nothrow @show 42
ERROR: LoadError: TypeError: in typeassert, expected Expr, got a value of type Int64
Stacktrace:

This commit addresses this issue.
* make faster BigFloats (#55906)
We can coalesce the two required allocations for the MFPR BigFloat API
design into one allocation, hopefully giving a easy performance boost.
It would have been slightly easier and more efficient if MPFR BigFloat
was already a VLA instead of containing a pointer here, but that does
not prevent the optimization.
* Add propagate_inbounds_meta to atomic genericmemory ops (#55902)
`memoryref(mem, i)` will otherwise emit a boundscheck.

* fix rounding mode in construction of `BigFloat` from pi (#55911)
The default argument of the method was outdated, reading the global
default rounding directly, bypassing the `ScopedValue` stuff.
* fix `nonsetable_type_hint_handler` (#55962)
The current implementation is wrong, causing it to display inappropriate

The function `setindex!` exists, but no method is defined for this combination of argument types.

* REPL: make UndefVarError aware of imported modules (#55932)

In particular, the implementation of `overdub_generator54341` was
dangerous. This fixes it up.
* Explicitly store a module's location (#55963)
Revise wants to know what file a module's `module` definition is in.
Currently it does this by looking at the source location for the
implicitly generated `eval` method. This is terrible for two reasons:
1. The method may not exist if the module is a baremodule (which is not
particularly common, which is probably why we haven't seen it).
2. The fact that the implicitly generated `eval` method has this
location information is an implementation detail that I'd like to get
rid of (#55949).
This PR adds explicit file/line info to `Module`, so that Revise doesn't
have to use the hack anymore.
* mergewith: add single argument example to docstring (#55964)
I ran into this edge case. I though it should be documented.

* [build] avoid libedit linkage and align libccalllazy* SONAMEs (#55968)
While building the 1.11.0-rc4 in Homebrew[^1] in preparation for 1.11.0
release (and to confirm Sequoia successfully builds) I noticed some odd
linkage for our Linux builds, which included of:
1. LLVM libraries were linking to `libedit.so`, e.g.
```
Dynamic Section:
NEEDED libedit.so.0
NEEDED libz.so.1
NEEDED libzstd.so.1
NEEDED libstdc++.so.6
NEEDED libm.so.6
NEEDED libgcc_s.so.1
NEEDED libc.so.6
NEEDED ld-linux-x86-64.so.2
SONAME libLLVM-16jl.so
```
CMakeCache.txt showed
```
//Use libedit if available.
LLVM_ENABLE_LIBEDIT:BOOL=ON
```
Which might be overriding `HAVE_LIBEDIT` at
https://github.com/JuliaLang/llvm-project/blob/julia-release/16.x/llvm/cmake/config-ix.cmake#L222-L225.
So just added `LLVM_ENABLE_LIBEDIT`
2. Wasn't sure if there was a reason for this but `libccalllazy*` had
mismatched SONAME:
```console
❯ objdump -p lib/julia/libccalllazy* | rg '\.so'
lib/julia/libccalllazybar.so: file format elf64-x86-64
NEEDED ccalllazyfoo.so
SONAME ccalllazybar.so
lib/julia/libccalllazyfoo.so: file format elf64-x86-64
SONAME ccalllazyfoo.so
```
Modifying this, but can drop if intentional.

* Add missing `copy!(::AbstractMatrix, ::UniformScaling)` method (#55970)
Hi everyone! First PR to Julia here.
It was noticed in a Slack thread yesterday
that `copy!(A, I)` doesn't work, but `copyto!(A, I)` does. This PR adds
the missing method for `copy!(::AbstractMatrix, ::UniformScaling)`,
which simply defers to `copyto!`, and corresponding tests.
I added a `compat` notice for Julia 1.12.

* Fix an intermittent test failure in `core` test (#55973)
The test wants to assert that `Module` is not resolved in `Main`, but

that by running the test in a fresh subprocess.

* Add filesystem func to transform a path to a URI (#55454) In a few places across Base and the stdlib, we emit paths that we like people to be able to click on in their terminal and editor. Up to this point, we have relied on auto-filepath detection, but this does not allow for alternative link text, such as contracted paths. Doing so (via OSC 8 terminal links for example) requires filepath URI encoding. This functionality was previously part of a PR modifying stacktrace printing (#51816), but after that became held up for unrelated reasons and another PR appeared that would benefit from this utility (#55335), I've split out this functionality so it can be used before the stacktrace printing PR is resolved. * constrain the path argument of `include` functions to `AbstractString` (#55466) Each `Module` defined with `module` automatically gets an `include` function with two methods. Each of those two methods takes a file path as its last argument. Even though the path argument is unconstrained by dispatch, it's documented as constrained with `::AbstractString`: https://docs.julialang.org/en/v1.11-dev/base/base/#include Furthermore, I think that any invocation of `include` with a non-`AbstractString` path will necessarily throw a `MethodError` eventually. Thus this change should be harmless. Adding the type constraint to the path argument is an improvement because any possible exception would be thrown earlier than before. Apart from modules defined with `module`, the same issue is present with the anonymous modules created by `evalfile`, which is also addressed. Sidenote: `evalfile` seems to be completely untested apart from the test added here.

This packing requires some care at the boundaries and if the expected field alignment exceeds that of a pointer. The change is expected to eventually make codegen more flexible at representing unions of values with both bits and pointer regions. Eventually we can also have someone improve the late-gc-lowering pass to take advantage of this increased information accuracy, but currently it will not be any better than before at laying out the frame. * Refactoring to be considered before adding MMTk * Removing jl_gc_notify_image_load, since it's a new function and not part of the refactoring * Moving gc_enable code to gc-common.c * Addressing PR comments * Push resolution of merge conflict * Removing jl_gc_mark_queue_obj_explicit extern definition from scheduler.c * Don't need the getter function since it's possible to use jl_small_typeof directly * WIP: Adding support for MMTk/Immix * Refactoring to be considered before adding MMTk * Adding fastpath allocation * Fixing removed newlines * Refactoring to be considered before adding MMTk * Adding a few comments; Moving some functions to be closer together * Fixing merge conflicts * Applying changes from refactoring before adding MMTk * Update TaskLocalRNG docstring according to #49110 (#55863) Since #49110, which is included in 1.10 and 1.11, spawning a task no longer advances the parent task's RNG state, so this statement in the docs was incorrect. * Root globals in toplevel exprs (#54433) This fixes #54422, the code here assumes that top level exprs are always rooted, but I don't see that referenced anywhere else, or guaranteed, so conservatively always root objects that show up in code. * codegen: fix alignment typos (#55880) So easy to type jl_datatype_align to get the natural alignment instead of julia_alignment to get the actual alignment.

Specifically, `t.a` and `t.b` from `t::Union` could be `TypeVar`, and if they are passed to a subroutine or recursed without being unwrapped or rewrapped, errors like JuliaLang/julia#55882 could occur. This commit resolves the issue by calling `unwraptv` in the `Union` handling within `instanceof_tfunc`. I also found a similar issue inside `nfields_tfunc`, so that has also been fixed, and test cases have been added.

This will help us to diagnose why some of our servers are triggering so many full GCs in certain circumstances. * Revert "Improve printing of several arguments" (#55894) Reverts JuliaLang/julia#55754 as it overrode some performance heuristics which appeared to be giving a significant gain/loss in performance: Closes https://github.com/JuliaLang/julia/issues/55893 * Do not trigger deprecation warnings in `Test.detect_ambiguities` and `Test.detect_unbound_args` (#55869) #55868 * do not intentionally suppress errors in precompile script from being reported or failing the result (#55909) I was slightly annoying that the build was set up to succeed if this step failed, so I removed the error suppression and fixed up the script slightly * Remove eigvecs method for SymTridiagonal (#55903) The fallback method does the same, so this specialized method isn't necessary * add --trim option for generating smaller binaries (#55047) This adds a command line option `--trim` that builds images where code is only included if it is statically reachable from methods marked using the new function `entrypoint`. Compile-time errors are given for call sites that are too dynamic to allow trimming the call graph (however there is an `unsafe` option if you want to try building anyway to see what happens). The PR has two other components. One is changes to Base that generally allow more code to be compiled in this mode. These changes will either be merged in separate PRs or moved to a separate part of the workflow (where we will build a custom system image for this purpose). The branch is set up this way to make it easy to check out and try the functionality. The other component is everything in the `juliac/` directory, which implements a compiler driver script based on this new option, along with some examples and tests. This will eventually become a package "app" that depends on PackageCompiler and provides a CLI for all of this stuff, so it will not be merged here. To try an example: ``` julia contrib/juliac.jl --output-exe hello --trim test/trimming/hello.jl ``` When stripped the resulting executable is currently about 900kb on my machine.

For example, if you have more than one extension and you happen to transitively depend on the triggers of one of your extensions you will immediately hit a cycle where the extensions will try to load each other indefinitely. This is an issue because you cannot directly influence your transitive dependency graph so from this p.o.v the current system of loading extension is "unsound". The test added here checks this scenario and we can now precompile and load it without any warnings or issues. Would have made https://github.com/JuliaLang/julia/issues/55517 a non issue. Fixes https://github.com/JuliaLang/julia/issues/55557 --------- Co-authored-by: KristofferC <[email protected]> * TOML: Avoid type-pirating `Base.TOML.Parser` (#55892) Since stdlibs can be duplicated but Base never is, `Base.require_stdlib` makes type piracy even more complicated than it normally would be. To adapt, this changes `TOML.Parser` to be a type defined by the TOML stdlib, so that we can define methods on it without committing type-piracy and avoid problems like Pkg.jl#4017 Resolves https://github.com/JuliaLang/Pkg.jl/issues/4017#issuecomment-2377589989 * [FileWatching] fix PollingFileWatcher design and add workaround for a stat bug What started as an innocent fix for a stat bug on Apple (#48667) turned into a full blown investigation into the design problems with the libuv backend for PollingFileWatcher, and writing my own implementation of it instead which could avoid those singled-threaded concurrency bugs. * [FileWatching] fix FileMonitor similarly and improve pidfile reliability Previously pidfile used the same poll_interval as sleep to detect if this code made any concurrency mistakes, but we do not really need to do that once FileMonitor is fixed to be reliable in the presence of parallel concurrency (instead of using watch_file). * [FileWatching] reorganize file and add docs * Add `--trace-dispatch` (#55848) * relocation: account for trailing path separator in depot paths (#55355) Fixes #55340 * change compiler to be stackless (#55575) This change ensures the compiler uses very little stack, making it compatible with running on any arbitrary system stack size and depths much more reliably. It also could be further modified now to easily add various forms of pause-able/resumable inference, since there is no implicit state on the stack--everything is local and explicit now. Whereas before, less than 900 frames would crash in less than a second: ``` $ time ./julia -e 'f(::Val{N}) where {N} = N <= 0 ? 0 : f(Val(N - 1)); f(Val(1000))' Warning: detected a stack overflow; program state may be corrupted, so further execution might be unreliable. Internal error: during type inference of f(Base.Val{1000}) Encountered stack overflow. This might be caused by recursion over very long tuples or argument lists.

Previously, it required that the finalizer registration dominate all uses, but this is not always necessary as far as the finalizer inlining point dominates all the uses. So the check has been relaxed. Other minor fixes have been made as well, but their importance is low. * Limit `@inbounds` to indexing in the dual-iterator branch in `copyto_unaliased!` (#55919) This simplifies the `copyto_unalised!` implementation where the source and destination have different `IndexStyle`s, and limits the `@inbounds` to only the indexing operation. In particular, the iteration over `eachindex(dest)` is not marked as `@inbounds` anymore. This seems to help with performance when the destination uses Cartesian indexing. Reduced implementation of the branch: ```julia function copyto_proposed!(dest, src) axes(dest) == axes(src) || throw(ArgumentError("incompatible sizes")) iterdest, itersrc = eachindex(dest), eachindex(src) for (destind, srcind) in zip(iterdest, itersrc) @inbounds dest[destind] = src[srcind] end dest end function copyto_current!(dest, src) axes(dest) == axes(src) || throw(ArgumentError("incompatible sizes")) iterdest, itersrc = eachindex(dest), eachindex(src) ret = iterate(iterdest) @inbounds for a in src idx, state = ret::NTuple{2,Any} dest[idx] = a ret = iterate(iterdest, state) end dest end function copyto_current_limitinbounds!(dest, src) axes(dest) == axes(src) || throw(ArgumentError("incompatible sizes")) iterdest, itersrc = eachindex(dest), eachindex(src) ret = iterate(iterdest) for isrc in itersrc idx, state = ret::NTuple{2,Any} @inbounds dest[idx] = src[isrc] ret = iterate(iterdest, state) end dest end ``` ```julia julia> a = zeros(40000,4000); b = rand(size(a)...); julia> av = view(a, UnitRange.(axes(a))...); julia> @btime copyto_current!($av, $b); 617.704 ms (0 allocations: 0 bytes) julia> @btime copyto_current_limitinbounds!($av, $b); 304.146 ms (0 allocations: 0 bytes) julia> @btime copyto_proposed!($av, $b); 240.217 ms (0 allocations: 0 bytes) julia> versioninfo() Julia Version 1.12.0-DEV.1260 Commit 4a4ca9c8152 (2024-09-28 01:49 UTC) Build Info: Official https://julialang.org release Platform Info: OS: Linux (x86_64-linux-gnu) CPU: 8 × Intel(R) Core(TM) i5-10310U CPU @ 1.70GHz WORD_SIZE: 64 LLVM: libLLVM-18.1.7 (ORCJIT, skylake) Threads: 1 default, 0 interactive, 1 GC (on 8 virtual cores) Environment: JULIA_EDITOR = subl ``` I'm not quite certain why the proposed implementation here (`copyto_proposed!`) is even faster than `copyto_current_limitinbounds!`. In any case, `copyto_proposed!` is easier to read, so I'm not complaining. This fixes https://github.com/JuliaLang/julia/issues/53158 * Strong zero in Diagonal triple multiplication (#55927) Currently, triple multiplication with a `LinearAlgebra.BandedMatrix` sandwiched between two `Diagonal`s isn't associative, as this is implemented using broadcasting, which doesn't assume a strong zero, whereas the two-term matrix multiplication does. ```julia julia> D = Diagonal(StepRangeLen(NaN, 0, 3)); julia> B = Bidiagonal(1:3, 1:2, :U); julia> D * B * D 3×3 Matrix{Float64}: NaN NaN NaN NaN NaN NaN NaN NaN NaN julia> (D * B) * D 3×3 Bidiagonal{Float64, Vector{Float64}}: NaN NaN ⋅ ⋅ NaN NaN ⋅ ⋅ NaN julia> D * (B * D) 3×3 Bidiagonal{Float64, Vector{Float64}}: NaN NaN ⋅ ⋅ NaN NaN ⋅ ⋅ NaN ``` This PR ensures that the 3-term multiplication is evaluated as a sequence of two-term multiplications, which fixes this issue. This also improves performance, as only the bands need to be evaluated now. ```julia julia> D = Diagonal(1:1000); B = Bidiagonal(1:1000, 1:999, :U); julia> @btime $D * $B * $D; 656.364 μs (11 allocations: 7.63 MiB) # v"1.12.0-DEV.1262" 2.483 μs (12 allocations: 31.50 KiB) # This PR ``` * Fix dispatch on `alg` in Float16 Hermitian eigen (#55928) Currently, ```julia julia> using LinearAlgebra julia> A = Hermitian(reshape(Float16[1:16;], 4, 4)); julia> eigen(A).values |> typeof Vector{Float16} (alias for Array{Float16, 1}) julia> eigen(A, LinearAlgebra.QRIteration()).values |> typeof Vector{Float32} (alias for Array{Float32, 1}) ``` This PR moves the specialization on the `eltype` to an internal method, so that firstly all `alg`s dispatch to that method, and secondly, there are no ambiguities introduce by specializing the top-level `eigen`. The latter currently causes test failures in `StaticArrays` (https://github.com/JuliaArrays/StaticArrays.jl/actions/runs/11092206012/job/30816955210?pr=1279), and should be fixed by this PR. * Remove specialized `ishermitian` method for `Diagonal{<:Real}` (#55948) The fallback method for `Diagonal{<:Number}` handles this already by checking that the `diag` is real, so we don't need this additional specialization. * Fix logic in `?` docstring example (#55945) * fix `unwrap_macrocalls` (#55950) The implementation of `unwrap_macrocalls` has assumed that what `:macrocall` wraps is always an `Expr` object, but that is not necessarily correct: ```julia julia> Base.@assume_effects :nothrow @show 42 ERROR: LoadError: TypeError: in typeassert, expected Expr, got a value of type Int64 Stacktrace: [1] unwrap_macrocalls(ex::Expr) @ Base ./expr.jl:906 [2] var"@assume_effects"(__source__::LineNumberNode, __module__::Module, args::Vararg{Any}) @ Base ./expr.jl:756 in expression starting at REPL[1]:1 ``` This commit addresses this issue. * make faster BigFloats (#55906) We can coalesce the two required allocations for the MFPR BigFloat API design into one allocation, hopefully giving a easy performance boost. It would have been slightly easier and more efficient if MPFR BigFloat was already a VLA instead of containing a pointer here, but that does not prevent the optimization. * Add propagate_inbounds_meta to atomic genericmemory ops (#55902) `memoryref(mem, i)` will otherwise emit a boundscheck. ``` ; │ @ /home/vchuravy/WorkstealingQueues/src/CLL.jl:53 within `setindex_atomic!` @ genericmemory.jl:329 ; │┌ @ boot.jl:545 within `memoryref` %ptls_field = getelementptr inbounds i8, ptr %tls_pgcstack, i64 16 %ptls_load = load ptr, ptr %ptls_field, align 8 %"box::GenericMemoryRef" = call noalias nonnull align 8 dereferenceable(32) ptr @ijl_gc_small_alloc(ptr %ptls_load, i32 552, i32 32, i64 23456076646928) #9 %"box::GenericMemoryRef.tag_addr" = getelementptr inbounds i64, ptr %"box::GenericMemoryRef", i64 -1 store atomic i64 23456076646928, ptr %"box::GenericMemoryRef.tag_addr" unordered, align 8 store ptr %memoryref_data, ptr %"box::GenericMemoryRef", align 8 %.repack8 = getelementptr inbounds { ptr, ptr }, ptr %"box::GenericMemoryRef", i64 0, i32 1 store ptr %memoryref_mem, ptr %.repack8, align 8 call void @ijl_bounds_error_int(ptr nonnull %"box::GenericMemoryRef", i64 %7) unreachable ``` For the Julia code: ```julia function Base.setindex_atomic!(buf::WSBuffer{T}, order::Symbol, val::T, idx::Int64) where T @inbounds Base.setindex_atomic!(buf.buffer, order, val,((idx - 1) & buf.mask) + 1) end ``` from https://github.com/gbaraldi/WorkstealingQueues.jl/blob/0ebc57237cf0c90feedf99e4338577d04b67805b/src/CLL.jl#L41 * fix rounding mode in construction of `BigFloat` from pi (#55911) The default argument of the method was outdated, reading the global default rounding directly, bypassing the `ScopedValue` stuff. * fix `nonsetable_type_hint_handler` (#55962) The current implementation is wrong, causing it to display inappropriate hints like the following: ```julia julia> s = Some("foo"); julia> s[] = "bar" ERROR: MethodError: no method matching setindex!(::Some{String}, ::String) The function `setindex!` exists, but no method is defined for this combination of argument types.

Currently it does this by looking at the source location for the implicitly generated `eval` method. This is terrible for two reasons: 1. The method may not exist if the module is a baremodule (which is not particularly common, which is probably why we haven't seen it). 2. The fact that the implicitly generated `eval` method has this location information is an implementation detail that I'd like to get rid of (#55949). This PR adds explicit file/line info to `Module`, so that Revise doesn't have to use the hack anymore. * mergewith: add single argument example to docstring (#55964) I ran into this edge case.

LLVM libraries were linking to `libedit.so`, e.g. ``` Dynamic Section: NEEDED libedit.so.0 NEEDED libz.so.1 NEEDED libzstd.so.1 NEEDED libstdc++.so.6 NEEDED libm.so.6 NEEDED libgcc_s.so.1 NEEDED libc.so.6 NEEDED ld-linux-x86-64.so.2 SONAME libLLVM-16jl.so ``` CMakeCache.txt showed ``` //Use libedit if available.

So just added `LLVM_ENABLE_LIBEDIT` 2. Wasn't sure if there was a reason for this but `libccalllazy*` had mismatched SONAME: ```console ❯ objdump -p lib/julia/libccalllazy* | rg '\.so' lib/julia/libccalllazybar.so: file format elf64-x86-64 NEEDED ccalllazyfoo.so SONAME ccalllazybar.so lib/julia/libccalllazyfoo.so: file format elf64-x86-64 SONAME ccalllazyfoo.so ``` Modifying this, but can drop if intentional. --- [^1]: https://github.com/Homebrew/homebrew-core/pull/192116 * Add missing `copy!(::AbstractMatrix, ::UniformScaling)` method (#55970) Hi everyone!

Specifically, using `nargs`/`isva` from `mi.def::Method` in `ir_prepare_inlining!` causes the following error to occur: ```julia function generate_lambda_ex(world::UInt, source::LineNumberNode, argnames, spnames, @nospecialize body) stub = Core.GeneratedFunctionStub(identity, Core.svec(argnames...), Core.svec(spnames...)) return stub(world, source, body) end function overdubbee54341(a, b) return a + b end const overdubee_codeinfo54341 = code_lowered(overdubbee54341, Tuple{Any, Any})[1] function overdub_generator54341(world::UInt, source::LineNumberNode, selftype, fargtypes) if length(fargtypes) != 2 return generate_lambda_ex(world, source, (:overdub54341, :args), (), :(error("Wrong number of arguments"))) else return copy(overdubee_codeinfo54341) end end @eval function overdub54341(args...) $(Expr(:meta, :generated, overdub_generator54341)) $(Expr(:meta, :generated_only)) end topfunc(x) = overdub54341(x, 2) ``` ```julia julia> topfunc(1) Internal error: during type inference of topfunc(Int64) Encountered unexpected error in runtime: BoundsError(a=Array{Any, 1}(dims=(2,), mem=Memory{Any}(8, 0x10632e780)[SSAValue(2), SSAValue(3), #<null>, #<null>, #<null>, #<null>, #<null>, #<null>]), i=(3,)) throw_boundserror at ./essentials.jl:14 getindex at ./essentials.jl:909 [inlined] ssa_substitute_op! at ./compiler/ssair/inlining.jl:1798 ssa_substitute_op! at ./compiler/ssair/inlining.jl:1852 ir_inline_item! at ./compiler/ssair/inlining.jl:386 ... ``` This commit updates the abstract interpretation and inlining algorithm to use the `nargs`/`isva` values held by `CodeInfo`.

Fix #55998. * cleanup functions of Hermitian matrices (#55951) The functions of Hermitian matrices are a bit of a mess. For example, if we have a Hermitian matrix `a` with negative eigenvalues, `a^0.5` doesn't produce the `Symmetric` wrapper, but `sqrt(a)` does. On the other hand, if we have a positive definite `b`, `b^0.5` will be `Hermitian`, but `sqrt(b)` will be `Symmetric`: ```julia using LinearAlgebra a = Hermitian([1.0 2.0;2.0 1.0]) a^0.5 sqrt(a) b = Hermitian([2.0 1.0; 1.0 2.0]) b^0.5 sqrt(b) ``` This sort of arbitrary assignment of wrappers happens with pretty much all functions defined there. There's also some oddities, such as `cis` being the only function defined for `SymTridiagonal`, even though all `eigen`-based functions work, and `cbrt` being the only function not defined for complex Hermitian matrices. I did a cleanup: I defined all functions for `SymTridiagonal` and `Hermitian{<:Complex}`, and always assigned the appropriate wrapper, preserving the input one when possible. There's an inconsistency remaining that I didn't fix, that only `sqrt` and `log` accept a tolerance argument, as changing that is probably breaking. There were also hardly any tests that I could find (only `exp`, `log`, `cis`, and `sqrt`). I'm happy to add them if it's desired. * Fix no-arg `ScopedValues.@with` within a scope (#56019) Fixes https://github.com/JuliaLang/julia/issues/56017 * LinearAlgebra: make matprod_dest public (#55537) Currently, in a matrix multiplication `A * B`, we use `B` to construct the destination. However, this may not produce the optimal destination type, and is essentially single-dispatch. Letting packages specialize `matprod_dest` would help us obtain the optimal type by dispatching on both the arguments. This may significantly improve performance in the matrix multiplication. As an example: ```julia julia> using LinearAlgebra, FillArrays, SparseArrays julia> F = Fill(3, 10, 10); julia> s = sprand(10, 10, 0.1); julia> @btime $F * $s; 15.225 μs (10 allocations: 4.14 KiB) julia> typeof(F * s) SparseMatrixCSC{Float64, Int64} julia> nnz(F * s) 80 julia> VERSION v"1.12.0-DEV.1074" ``` In this case, the destination is a sparse matrix with 80% of its elements filled and being set one-by-one, which is terrible for performance. Instead, if we specialize `matprod_dest` to return a dense destination, we may obtain ```julia julia> LinearAlgebra.matprod_dest(F::FillArrays.AbstractFill, S::SparseMatrixCSC, ::Type{T}) where {T} = Matrix{T}(undef, size(F,1), size(S,2)) julia> @btime $F * $s; 754.632 ns (2 allocations: 944 bytes) julia> typeof(F * s) Matrix{Float64} ``` Potentially, this may be improved further by specializing `mul!`, but this is a 20x improvement just by choosing the right destination. Since this is being made public, we may want to bikeshed on an appropriate name for the function. * Sockets: Warn when local network access not granted.

This is because `SymTridiagonal` symmetrizes the values along the diagonal, so setting a diagonal entry to an asymmetric value would lead to a subsequent `getindex` producing a different result. ```julia julia> s = SMatrix{2,2}(1:4); julia> S = SymTridiagonal(fill(s,4), fill(s,3)) 4×4 SymTridiagonal{SMatrix{2, 2, Int64, 4}, Vector{SMatrix{2, 2, Int64, 4}}}: [1 3; 3 4] [1 3; 2 4] ⋅ ⋅ [1 2; 3 4] [1 3; 3 4] [1 3; 2 4] ⋅ ⋅ [1 2; 3 4] [1 3; 3 4] [1 3; 2 4] ⋅ ⋅ [1 2; 3 4] [1 3; 3 4] julia> S[1,1] = s 2×2 SMatrix{2, 2, Int64, 4} with indices SOneTo(2)×SOneTo(2): 1 3 2 4 julia> S[1,1] == s false julia> S[1,1] 2×2 Symmetric{Int64, SMatrix{2, 2, Int64, 4}} with indices SOneTo(2)×SOneTo(2): 1 3 3 4 ``` After this PR, ```julia julia> S[1,1] = s ERROR: ArgumentError: cannot set a diagonal entry of a SymTridiagonal to an asymmetric value ``` * Remove unused matrix type params in diag methods (#56048) These parameters are not used in the method, and are unnecessary for dispatch. * LinearAlgebra: diagzero for non-OneTo axes (#55252) Currently, the off-diagonal zeros for a block-`Diagonal` matrix is computed using `diagzero`, which calls `zeros` for the sizes of the elements. This returns an `Array`, unless one specializes `diagzero` for the custom `Diagonal` matrix type. This PR defines a `zeroslike` function that dispatches on the axes of the elements, which lets packages specialize on the axes to return custom `AbstractArray`s. Choosing to specialize on the `eltype` avoids the need to specialize on the container, and allows packages to return appropriate types for custom axis types. With this, ```julia julia> LinearAlgebra.zeroslike(::Type{S}, ax::Tuple{SOneTo, Vararg{SOneTo}}) where {S<:SMatrix} = SMatrix{map(length, ax)...}(ntuple(_->zero(eltype(S)), prod(length, ax))) julia> D = Diagonal(fill(SMatrix{2,3}(1:6), 2)) 2×2 Diagonal{SMatrix{2, 3, Int64, 6}, Vector{SMatrix{2, 3, Int64, 6}}}: [1 3 5; 2 4 6] ⋅ ⋅ [1 3 5; 2 4 6] julia> D[1,2] # now an SMatrix 2×3 SMatrix{2, 3, Int64, 6} with indices SOneTo(2)×SOneTo(3): 0 0 0 0 0 0 julia> LinearAlgebra.zeroslike(::Type{S}, ax::Tuple{SOneTo, Vararg{SOneTo}}) where {S<:MMatrix} = MMatrix{map(length, ax)...}(ntuple(_->zero(eltype(S)), prod(length, ax))) julia> D = Diagonal(fill(MMatrix{2,3}(1:6), 2)) 2×2 Diagonal{MMatrix{2, 3, Int64, 6}, Vector{MMatrix{2, 3, Int64, 6}}}: [1 3 5; 2 4 6] ⋅ ⋅ [1 3 5; 2 4 6] julia> D[1,2] # now an MMatrix 2×3 MMatrix{2, 3, Int64, 6} with indices SOneTo(2)×SOneTo(3): 0 0 0 0 0 0 ``` The reason this can't be the default behavior is that we are not guaranteed that there exists a `similar` method that accepts the combination of axes. This is why we have to fall back to using the sizes, unless a specialized method is provided by a package. One positive outcome of this is that indexing into such a block-diagonal matrix will now usually be type-stable, which mitigates https://github.com/JuliaLang/julia/issues/45535 to some extent (although it doesn't resolve the issue). I've also updated the `getindex` for `Bidiagonal` to use `diagzero`, instead of the similarly defined `bidiagzero` function that it was using. Structured block matrices may now use `diagzero` uniformly to generate the zero elements. * Multi-argument `gcdx(a, b, c...)` (#55935) Previously, `gcdx` only worked for two arguments - but the underlying idea extends to any (nonzero) number of arguments. Similarly, `gcd` already works for 1, 2, 3+ arguments. This PR implements the 1 and 3+ argument versions of `gcdx`, following the [wiki page](https://en.wikipedia.org/wiki/Extended_Euclidean_algorithm#The_case_of_more_than_two_numbers) for the Extended Euclidean algorithm. * Refactoring to be considered before adding MMTk * Removing jl_gc_notify_image_load, since it's a new function and not part of the refactoring * Moving gc_enable code to gc-common.c * Addressing PR comments * Push resolution of merge conflict * Removing jl_gc_mark_queue_obj_explicit extern definition from scheduler.c * Don't need the getter function since it's possible to use jl_small_typeof directly * Remove extern from free_stack declaration in julia_internal.h * Putting everything that is common GC tls into gc-tls-common.h * Typo * Adding gc-tls-common.h to Makefile as a public header * Adding jl_full_sweep_reasons since timing.jl depends on it * Fixing issue with jl_full_sweep_reasons (missing constants) * fix `_growbeg!` unncessary resizing (#56029) This was very explicitly designed such that if there was a bunch of extra space at the end of the array, we would copy rather than allocating, but by making `newmemlen` be at least `overallocation(memlen)` rather than `overallocation(len)`, this branch was never hit. found by https://github.com/JuliaLang/julia/issues/56026 * REPL: hide any prints to stdio during `complete_line` (#55959) * teach llvm-alloc-helpers about `gc_loaded` (#56030) combined with https://github.com/JuliaLang/julia/pull/55913, the compiler is smart enough to fully remove ``` function f() m = Memory{Int}(undef, 3) @inbounds m[1] = 2 @inbounds m[2] = 2 @inbounds m[3] = 4 @inbounds return m[1] + m[2] + m[3] end ``` * mpfr: prevent changing precision (#56049) Changing precision requires reallocating the data field, which is better done by making a new BigFloat (since they are conceptually immutable anyways). Also do a bit a cleanup while here. Closes #56044 * stackwalk: fix jl_thread_suspend_and_get_state race (#56047) There was a missing re-assignment of old = -1; at the end of that loop which means in the ABA case, we accidentally actually acquire the lock on the thread despite not actually having stopped the thread; or in the counter-case, we try to run through this logic with old==-1 on the next iteration, and that isn't valid either (jl_thread_suspend_and_get_state should return failure and the loop will abort too early).

Also avoids some invalidations (https://github.com/JuliaLang/julia/issues/56080#issuecomment-2404765120) Co-authored-by: KristofferC <[email protected]> * array: inline `convert` where possible (#56034) This improves a common scenario, where someone wants to `push!` a poorly-typed object onto a well-typed Vector. For example: ```julia const NT = @NamedTuple{x::Int,y::Any} foo(v::Vector{NT}, x::Int, @nospecialize(y)) = push!(v, (; x, y)) ``` The `(; x, y)` is slightly poorly-typed here. It could have any type for its `.y` field before it is converted inside the `push!` to a NamedTuple with `y::Any` Without this PR, the dispatch for this `push!` cannot be inferred: ```julia julia> code_typed(foo, (Vector{NT}, Int, Any))[1] CodeInfo( 1 ─ ... │ %4 = %new(%3, x, y)::NamedTuple{(:x, :y), <:Tuple{Int64, Any}} │ %5 = Main.push!(v, %4)::Vector{@NamedTuple{x::Int64, y}} └── return %5 ) => Vector{@NamedTuple{x::Int64, y}} ``` With this PR, the above dynamic call is fully statically resolved and inlined (and therefore `--trim` compatible) * Remove some unnecessary `real` specializations for structured matrices (#56083) The `real(::AbstractArray{<:Rea})` fallback method should handle these cases correctly. * Combine `diag` methods for `SymTridiagonal` (#56014) Currently, there are two branches, one for an `eltype` that is a `Number`, and the other that deals with generic `eltype`s. They do similar things, so we may combine these, and use branches wherever necessary to retain the performance. We also may replace explicit materialized arrays by generators in `copyto!`. Overall, this improves performance in `diag` for matrices of matrices, whereas the performance in the common case of matrices of numbers remains unchanged. ```julia julia> using StaticArrays, LinearAlgebra julia> s = SMatrix{2,2}(1:4); julia> S = SymTridiagonal(fill(s,100), fill(s,99)); julia> @btime diag($S); 1.292 μs (5 allocations: 7.16 KiB) # nightly, v"1.12.0-DEV.1317" 685.012 ns (3 allocations: 3.19 KiB) # This PR ``` This PR also allows computing the `diag` for more values of the band index `n`: ```julia julia> diag(S,99) 1-element Vector{SMatrix{2, 2, Int64, 4}}: [0 0; 0 0] ``` This would work as long as `getindex` works for the `SymTridiagonal` for that band, and the zero element may be converted to the `eltype`. * fix `Vararg{T,T} where T` crashing `code_typed` (#56081) Not sure this is the right place to fix this error, perhaps `match.spec_types` should always be a tuple of valid types? fixes #55916 --------- Co-authored-by: Jameson Nash <[email protected]> * [libblastrampoline_jll] Upgrade to v5.11.1 (#56094) v5.11.1 is a patch release with a couple of RISC-V fixes. * Revert "REPL: hide any prints to stdio during `complete_line`" (#56102) * Remove warning from c when binding is ambiguous (#56103) * make `Base.ANSIIterator` have a concrete field (#56088) Avoids the invalidation ``` backedges: 1: superseding sizeof(s::AbstractString) @ Base strings/basic.jl:177 with MethodInstance for sizeof(::AbstractString) (75 children) ``` shown in https://github.com/JuliaLang/julia/issues/56080#issuecomment-2404765120.

(#56007) The main motivation of this PR is to fix #55807. dc689fe8700f70f4a4e2dbaaf270f26b87e79e04 tries to remove the slow `may_contain_union_decision` check by re-organizing the code path. Now the fast path has been removed and most of its optimization has been integrated into the preserved slow path. Since the slow path stores all inner ∃ decisions on the outer most R stack, there might be overflow risk. aee69a41441b4306ba3ee5e845bc96cb45d9b327 should fix that concern.

Not particularly fast, since it is just using the builtins implementation of setfield, and delaying the actual stores, but it should suffice. * improve OncePer implementation Address reviewer feedback, add more fixes and more tests, rename to add Once prefix. * fix use-after-free in test (detected in win32 CI) * Make loading work when stdlib deps are missing in the manifest (#56148) Closes https://github.com/JuliaLang/julia/issues/56109 Simulating a bad manifest by having `LibGit2_jll` missing as a dep of `LibGit2` in my default env, say because the manifest was generated by a different julia version or different master julia commit. ## This PR, it just works ``` julia> using Revise julia> ``` i.e. ``` % JULIA_DEBUG=loading ./julia --startup-file=no julia> using Revise ... ┌ Debug: Stdlib LibGit2 [76f85450-5226-5b5a-8eaa-529ad045b433] is trying to load `LibGit2_jll` │ which is not listed as a dep in the load path manifests, so resorting to search │ in the stdlib Project.tomls for true deps └ @ Base loading.jl:387 ┌ Debug: LibGit2 [76f85450-5226-5b5a-8eaa-529ad045b433] indeed depends on LibGit2_jll in project /Users/ian/Documents/GitHub/julia/usr/share/julia/stdlib/v1.12/LibGit2/Project.toml └ @ Base loading.jl:395 ... julia> ``` ## Master ``` julia> using Revise Info Given Revise was explicitly requested, output will be shown live ERROR: LoadError: ArgumentError: Package LibGit2 does not have LibGit2_jll in its dependencies: - Note that the following manifests in the load path were resolved with a potentially different DEV version of the current version, which may be the cause of the error. Try to re-resolve them in the current version, or consider deleting them if that fails: /Users/ian/.julia/environments/v1.12/Manifest.toml - You may have a partially installed environment. Try `Pkg.instantiate()` to ensure all packages in the environment are installed. - Or, if you have LibGit2 checked out for development and have added LibGit2_jll as a dependency but haven't updated your primary environment's manifest file, try `Pkg.resolve()`. - Otherwise you may need to report an issue with LibGit2 ... ``` * Remove llvm-muladd pass and move it's functionality to to llvm-simdloop (#55802) Closes https://github.com/JuliaLang/julia/issues/55785 I'm not sure if we want to backport this like this. Because that removes some functionality (the pass itself). So LLVM.jl and friends might need annoying version code. We can maybe keep the code there and just not run the pass in a backport. * Fix implicit `convert(String, ...)` in several places (#56174) This removes several `convert(String, ...)` from this code, which really shouldn't be something we invalidate on in the first place (see https://github.com/JuliaLang/julia/issues/56173) but this is still an improvement in code quality so let's take it. * Change annotations to use a NamedTuple (#55741) Due to popular demand, the type of annotations is to be changed from a `Tuple{UnitRange{Int}, Pair{Symbol, Any}}` to a `NamedTuple{(:region, :label, :value), Tuple{UnitRange{Int}, Symbol, Any}}`. This requires the expected code churn to `strings/annotated.jl`, and some changes to the StyledStrings and JuliaSyntaxHighlighting libraries. Closes #55249 and closes #55245. * Getting rid of mmtk_julia.c in the binding and moving it to gc-mmtk.c * Trying to organize and label the code in gc-mmtk.c * Remove redundant `convert` in `_setindex!` (#56178) Follow up to #56034, ref: https://github.com/JuliaLang/julia/pull/56034#discussion_r1798573573. --------- Co-authored-by: Cody Tapscott <[email protected]> * Improve type inference of Artifacts.jl (#56118) This also has some changes that move platform selection to compile time together with https://github.com/JuliaPackaging/JLLWrappers.jl/commit/45cc04963f3c99d4eb902f97528fe16fc37002cc, move the platform selection to compile time. (this helps juliac a ton) * Initial support for RISC-V (#56105) Rebase and extension of @alexfanqi's initial work on porting Julia to RISC-V. Requires LLVM 19. Tested on a VisionFive2, built with: ```make MARCH := rv64gc_zba_zbb MCPU := sifive-u74 USE_BINARYBUILDER:=0 DEPS_GIT = llvm override LLVM_VER=19.1.1 override LLVM_BRANCH=julia-release/19.x override LLVM_SHA1=julia-release/19.x ``` ```julia-repl ❯ ./julia _ _ _ _(_)_ | Documentation: https://docs.julialang.org (_) | (_) (_) | _ _ _| |_ __ _ | Type "?" for help, "]?" for Pkg help. | | | | | | |/ _` | | | | |_| | | | (_| | | Version 1.12.0-DEV.1374 (2024-10-14) _/ |\__'_|_|_|\__'_| | riscv/25092a3982* (fork: 1 commits, 0 days) |__/ | julia> versioninfo(; verbose=true) Julia Version 1.12.0-DEV.1374 Commit 25092a3982* (2024-10-14 09:57 UTC) Platform Info: OS: Linux (riscv64-unknown-linux-gnu) uname: Linux 6.11.3-1-riscv64 #1 SMP Debian 6.11.3-1 (2024-10-10) riscv64 unknown CPU: …

In order to help avoid memory provenance issues, and better utilize stack space (somewhat), and use FCA less, change the preferred representation of an immutable object to be a pair of
<packed-data,roots>values. This packing requires some care at the boundaries and if the expected field alignment exceeds that of a pointer. The change is expected to eventually make codegen more flexible at representing unions of values with both bits and pointer regions.Eventually we can also have someone improve the late-gc-lowering pass to take advantage of this increased information accuracy, but currently it will not be any better than before at laying out the frame.
