cannot compile mctoll without assertions

[zyt755]

Hi, I want to compile mctoll without assertions. However, I tried many times and all failed. Is it possible to compile without assertions?

cmake -S llvm -B <build-dir> -G "Ninja" \
  -DLLVM_TARGETS_TO_BUILD="X86;ARM"  \
  -DLLVM_ENABLE_PROJECTS="clang;lld"      \
  -DCLANG_DEFAULT_PIE_ON_LINUX=OFF   \
  -DCMAKE_BUILD_TYPE=Release

I receive expected unqualifield-id error.

I comment the line and get the same error in another place. And I comment it again.

Thanks. I'll take a look as soon as I get a chance. In the meantime, can you make sure that the tip of your llvm-project tree matches the commit listed in llvm-project-git-commit-to-use.txt.

Thanks. Yes, I'm sure llvm-project tree matches the commit listed in llvm-project-git-commit-to-use.txt because I compiled the mctoll project many times and only failed when disable assertions.

1. applying the following patch

2. followed by configuring the build using the following command?

cmake -S llvm -B <build-dir> -G "Ninja"   \
      -DLLVM_TARGETS_TO_BUILD="X86;ARM"    \
     -DLLVM_ENABLE_PROJECTS="clang;lld"        \
