[llvm-dev] Compiler-rt Build Fails and OpenMP Tests Fail on Non-Debian 32-bit Distros: bits/c++config.h not found
I just ran a clean build of main on an updated Arch Linux 32 and i686 OpenSUSE Tumbleweed. The build and tests are still failing. Do we really want to keep a Debian specific patch that breaks all other distros? More details over at https://bugs.llvm.org/show_bug.cgi?id=50303 -Luke
