Author: ctopper Date: Wed Mar 20 13:25:28 2019 New Revision: 356609 URL: http://llvm.org/viewvc/llvm-project?rev=356609&view=rev Log: [X86] Add __crc32b/__crc32w/__crc32d/__crc32q intrinsics to match gcc and icc.
gcc has these intrinsics in ia32intrin.h as well. And icc implements them though they aren't documented in the Intel Intrinsics Guide.
