This also means that over time compiler-rt is not guaranteed to\n  build against older versions of LLVM (or newer versions), and we often want to\n  work with multiple versions of LLVM simultaneously.\n\nThe makefiles and rustbuild already know how to compile C code, the code here is\nfar from the *only* C code we're compiling. This patch jettisons all logic to\nwork with compiler-rt's build system and just goes straight to the source. We\njust list all files manually (copied from compiler-rt's\nlib/builtins/CMakeLists.txt) and compile them into an archive.\n\nIt's likely that this means we'll fail to pick up new files when we upgrade\ncompiler-rt, but that seems like a much less significant cost to pay than what\nwe're currently paying.\n\ncc #34400, first steps towards that","distinct":true,"url":"https://api.github.com/repos/brson/rust/commits/349c57d2ec7648516eab68871e12ce8735436589"}]}
