clang-gcc-wrapper

Clang/GCC Compilers Wrapper for MSYS2 written in C#

Goal:

A wrapper that take clang/gcc arguments and forwards it to the original clang/gcc while adding aggressive compiler optimizations, eliminating the need to edit Makefiles for individual projects to tweak the compiler's flags.

How to use:

1. Compile .sln project, or download precompiled binary.
2. Copy 'Release\clang-wrapper.exe' to MSYS2 Root /mingw64/bin/ (works also with 32-bit /mingw32/bin).
3. Rename original "clang.exe" & "clang++.exe" or "gcc.exe" & "g++.exe" to: clang_.exe & clang++_.exe gcc_.exe & g++_.exe
4. Make copies of clang-wrapper.exe and rename them to: "clang.exe" & "clang++.exe" or "gcc.exe" & "g++.exe". Additional Options:

• you can override the wrapper optimization flags by creating text files compiler_flags.txt with custom flags.
• you can enable Clang Full LTO (Full LInk Time Optimizations) by creating a file: enable_clang_lto, remove to disable it.

Future Features:

• ability to wrap and forward from MSVC clang-cl.exe to MSYS2 clang.exe.
• additional wrappers for the linker and assemblers for better LTO.
