[swift-dev] [Swift CI] Build Failure: 0. OSS - Swift Incremental RA - OS X (master) #7279

[Kuba Mracek]

Sorry, Jordan :(

I don't think the "-mthread-model core2" error is caused by me.  Also, it seems that Swift is building compiler-rt in a different way than it's usually used in LLVM/Clang, which is why such errors are only triggered in Swift in not in the Clang buildbots.  Do you know why is that?  I'm noticed two differences:

1) compiler-rt is built with the just-built Clang, instead of the host compiler
2) compiler-rt is not built as a top-level project, but as a sub-build of Clang (via llvm/tools/clang/runtime/CMakeLists.txt)

If there's some issue that something is not rebuilt when it should be, that's also pretty bad...
