LLVM Custom Builds
+
+
+
+ 
+
+
+ 
+
+
+
+
+
+
+
+> Go along your path, this is a dangerous place.
+
+This repository contains a small `build.sh` (or `build.ps1` for Windows
+PowerShell) script that builds LLVM. The version of LLVM is defined in the CI script.
+The build is run by [Github
+Actions](https://github.com/wasmerio/llvm-custom-builds/actions) on 4
+platforms: Linux (Ubuntu, amd64 and aarch64), Darwin (macOS), and Windows.
+Builds are attached to [Github releases as
+assets](https://github.com/wasmerio/llvm-custom-builds/releases).
+
+## Prebuilds
+
+
+
+## LLVM configuration
+
+The following configuration is the one used for all actual prebuilds:
+
+| Options | Value |
+|-|-|
+| `clang` | enabled |
+| `docs` | not included |
+| `examples` | not included |
+| `go_tests` | not included |
+| `lld` | enabled |
+| `optimized_tablegen` | enabled |
+| `targets_to_build` | `X86` + `AArch64` |
+| `terminfo` | disabled |
+| `tests` | not included |
+| `tools` | included |
+| `utils` | not included |
+| `zlib` | disabled |
