Do you really need to build the C library for MLIR? If so, it looks like it's just a missing dependency - MPFR library. Or if you do have that library available, it's missing expected features.

That is slowing down the build visibly, for the speed I should stick with ld at the moment.

Good news, I was able to use up to 37 cores for LLVM build with LLD. The build speed, did not measure precisely though, is comparable to the build with GNU ld case. Thank you all for your help!

My read of this problem is as follows. While libLLVM.dylib is being linked against -lxar when -DLLVM_LINK_LLVM_DYLIB:BOOL=ON is passed to cmake, the libLLVM.dylib is created with -Wl,-dead_strip such that

This also broke the build for MSVC when doing a debug build (though no builder seems to be picking up the failure!). After
