On clang 10 onwards, a Windows X86 Debug build results in a crash when
compiling a simple C program. I am using the following version of MSVC to build
clang:
Microsoft (R) C/C++ Optimizing Compiler Version 19.28.29336 for x86

Git bisect points to this patch as the culprit: https://reviews.llvm.org/D65249

Steps to reproduce the issue:

echo void foo() {} | clang -x c -

1.      <eof> parser at end of file
2.      Code generation
3.      Running pass 'Function Pass Manager' on module '-'.
4.      Running pass 'Expand Atomic instructions' on function '@f'

Are you sure this isn't the known MSVC bug for passing overaligned arguments in
debug builds?
https://developercommunity.visualstudio.com/content/problem/1179643/msvc-copies-overaligned-non-trivially-copyable-par.html
Duped into this:
https://developercommunity2.visualstudio.com/t/Incorrect-Code-Gen--Missing-Error/831543
Which is labeled "pending release".

We have pragmas to workaround that issue:
https://github.com/llvm/llvm-project/commit/4e3edef4b8b637c0c76897497eb7c66f00157210

Maybe the workaround wasn't enough.

Thanks for the pointers, Reid. My test case passes with the Visual Studio Preview v16.9.0-pre.4.0. So I guess this is a duplicate of the MSVC bug you pointed to. I will go ahead and mark this as duplicate of https://bugs.llvm.org/show_bug.cgi?id=46176.

Quuxplusone commented 3 years ago

We attempted to work around the bug by applying that pragma in the commit I linked. Do you have that workaround in your version of LLVM? Maybe we just need to apply it to other files where this is an issue, or if the pragma doesn't work, perhaps we could fix the issue by moving from /Od to /O1 in cmake.
