Hi, everyone.

Does anyone faced with the MSVC Debug build issues of clang-tblgen and llvm-tblgen?

I'm using Windows10 Pro. MSVC and GCC.

Here is my cmake setup: cmake -GNinja ../llvm -DLLVM_ENABLE_PROJECTS=clang -DLLVM_TARGETS_TO_BUILD=X86 -DCMAKE_BUILD_TYPE=Debug

When building debug with GCC, cmd shows next:

D:\llvm-project\buildn2\bin>clang-tblgen.exe --version LLVM (http://llvm.org/): LLVM version 11.0.0git DEBUG build with assertions. Default target: x86_64-w64-windows-gnu Host CPU: skylake D:\llvm-project\buildn2\bin>clang-tblgen.exe --help USAGE: clang-tblgen.exe [options] OPTIONS: Color Options: --color - Use colors in output (default=autodetect) When building debug with MSVC, cmd shows next: D:\llvm-project\buildvs\Debug\bin>clang-tblgen.exe --version LLVM (http://llvm.org/): LLVM version 11.0.0git DEBUG build with assertions. Default target: x86_64-pc-windows-msvc Host CPU: skylake D:\llvm-project\buildvs\Debug\bin>clang-tblgen.exe --help clang-tblgen.exe: Unknown command line argument '--help'. Try: 'clang-tblgen.exe --help' clang-tblgen.exe: Did you mean '--color'?

All other commands of tblgen.exe do not work as well(beside of --version), when using Debug MSVC. It blocks the whole build process at all.

When using Release builds, both compilers work fine. What's the problem could be?

Help please.
