What they don't know is that Clang already allows __thiscall on +non-member functions without this fork. For example the following is +acceptable in mainline Clang as well as this fork and produces the correct +output (_this in ecx, other args on the stack): + +```cpp +int __thiscall square(void *_this, int num) { + return num * num; +} +``` + +## Compiler Explorer + +The compiler is available on the [Compiler Explorer website](https://godbolt.org/z/j4dPsE8rq). + +## Motivation + +The goal of the project is not to recompile decomplied code in all cases, but rather to provide a familiar syntax for common patterns and reduce the amount of inline assembly and fiddling required when writing high-level patch code. However, by providing this syntax it is possible to recompile decompiled code in some cases. With the addition of [defs.h](#defs.h) most individual functions can be recompiled with little to no modification. Recompiling an entire binary will still require great effort, but is made easier by this project. + +## Status + +The project is semi-functional but lacks polish. Correct syntax will be accepted +and generate correct code in most cases; however, incorrect syntax is handled +largely by asserts and internal compiler errors, especially in X86_64. More work +needs to be done to take advantage of Clang's diagnostics infrastructure and +produce pretty errors rather than compiler stack traces. Additionally, some +incorrect syntax is accepted and ignored rather than reported. Currently, only +the X86_32 and X86_64 backends are supported. + +Next steps are to improve the diagnostics reporting as described above and fix +the bugs. Pull requests and issues are encouraged; especially pull requests +adding tests. + +## Enable and Disable the Extensions + +By default, the extensions are enabled. They can be disabled using the +Clang option `-fno-widberg-extensions`. + +## Verify Widberg Extensions Are Present + +The following construct can be used in source files to verify that the +widberg extensions are present: + +```cpp +#ifndef __has_feature +# define __has_feature(x) 0 // Compatibility with non-clang compilers. +#endif +#ifndef __has_extension +# define __has_extension __has_feature // Compatibility with pre-3.0 compilers. +#endif + +#if !__has_extension(widberg) +# error "This file requires a compiler that implements the widberg extensions." +#endif +``` + +Also, the preprocessor macro `__widberg__` is predefined if the extensions are present. + +## defs.h + +An alternative implementation of defs.h from the Hex-Rays decompiler sdk intended to be used with this project can be found at https://github.com/widberg/widberg-defs.
