URL: https://github.com/llvm/llvm-project/commit/d2cb18918498b8a39657af2a495eba3e983c159b DIFF: https://github.com/llvm/llvm-project/commit/d2cb18918498b8a39657af2a495eba3e983c159b.diff LOG: [X86] Use a do {} while (0) in the _MM_EXTRACT_FLOAT implementation. Previously we just used {}, but that doesn't work in situations like this. if (1) _MM_EXTRACT_FLOAT(d, x, n); else ... The semicolon would terminate the if.
