* [X86] Improve avx512-kconstraints-att_inline_asm.c to not be easily defeated ↵Craig Topper2019-04-151-32/+50
| | | | | | | | by deadcode elimination. Improve CHECK lines to check IR types used. NFC I plan to use this as the basis for backend IR test cases. We currently crash hard for using 32 or 64 bit mask registers without avx512bw. llvm-svn: 358435

* [x86][inline-asm][AVX512][clang][PART-1] Introducing "k" and "Yk" ↵Michael Zuckerman2016-10-311-0/+59
constraints for extended inline assembly, enabling use of AVX512 masked vectorized instructions. Commit on behalf of mharoush Extending inline assembly support, compatible with GCC as folowing: "k" constraint hints the compiler to select any of AVX512 k0-k7 registers. "Yk" constraint is a subset of "k" excluding k0 which is not allowd to be used as a mask. Reviewer: 1. rnk Differential Revision: https://reviews.llvm.org/D25063 llvm-svn: 285604
