Am I remembering this correctly? Yes, your memory is pretty accurate. The source in question is the "compiler-rt" runtime libraries: http://compiler-rt.llvm.org/. The compiler-rt source is copied into the gcc and llvm trees -- although on checking, the copy in the gcc source lacks the go integration bits. The one in llvm-toolchain appears to have everything (in fact it's a multi orig source package, and one of the orig tarballs is the compiler-rt stuff), so the golang-race-detector-runtime could be built from the llvm-toolchain source package. The only question is around versioning then -- I don't have any intuition as to how much difference there is between the revisions go builds they're objects from and the revision for the compiler-rt that's part of the current llvm package at all. I've just wussed out of thinking about that so far. I guess I could ask upstream...
