# Wrapper that can be used as MONO_EXECUTABLE_WRAPPER in mono-wrapper when running MSVC build
# mono-sgen.exe. Simplify the setup of VS and MSVC toolchain, primarly when running MSVC build
# mono-sgen.exe as AOT compiler, since it needs to locate libraries as well as ClangC2 and linker
# from VS MSVC for corresponding architecture.

# NOTE, MSVC build mono-sgen.exe AOT compiler currently support 64-bit AMD codegen. mono-sgen-msvc.bat will ony setup
# amd64 versions of VS MSVC build environment and corresponding ClangC2 compiler.

# Optimization, only run full build environment when running mono-sgen.exe as AOT compiler.
# If not, just run mono-sgen.exe with supplied arguments.
