URL: https://github.com/llvm/llvm-project/commit/28de0fb4863a3cfef06c26260219089123a80c2f DIFF: https://github.com/llvm/llvm-project/commit/28de0fb4863a3cfef06c26260219089123a80c2f.diff LOG: [RISCV] Set __GCC_HAVE_SYNC_COMPARE_AND_SWAP_x defines The RISCV target did not set the GCC atomic compare and swap defines, unlike other targets. This broke builds for things like glib on RISCV.
