From: Thomas Lively Date: Sat, 31 Aug 2019 00:12:29 +0000 (+0000) Subject: [WebAssembly] Add SIMD QFMA/QFMS X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=101ffdb0168928e0650f7c5990f098d0d0b4ca86;p=clang [WebAssembly] Add SIMD QFMA/QFMS Summary: Adds clang builtins and LLVM intrinsics for these experimental instructions. They are not implemented in engines yet, but that is ok because the user must opt into using them by calling the builtins.
