Another issue. I guess it is that it tries to find out the path with .exe but native tool clearly does not have .exe since we are canadian compiling windows llvm on linux

Here is another issue with MLIR. Don't know why. It looks like it links fewer libraries than it should

JonChesterfield commented 3 months ago

I think this is fixed for clang-pseudo-gen. It's definitely still broken for clang-ast-dump. Fixed the latter with https://github.com/llvm/llvm-project/commit/b4adb42151bbfa80be4cf6d076cbe5edf680693e - it might be worth opening a separate issue for the mlir one, that seems an independent failure mode.

tbaederr commented 3 months ago

@JonChesterfield It seems like this change causes the clang build to build certain things twice (I'm not sure what this is limited to). See for example this output:

The unused function warning is printed twice because the TU is built twice. To make matters worse, the clang-ast-dump build seems to have assertions disabled.
