Gabor Buella	4a02bf945e	[x86] Introduce the enclv instruction Summary: and use the -msgx flag as a requirement for the SGX instructions. Reviewers: craig.topper, zvi Reviewed By: craig.topper Differential Revision: https://reviews.llvm.org/D46436 llvm-svn: 331742	2018-05-08 07:11:05 +00:00
Simon Pilgrim	2db2851378	[X86][MPX] Tag TSX/HLE/SGX instructions scheduler classes Currently tagged these as system instructions. llvm-svn: 320177	2017-12-08 19:26:22 +00:00
Craig Topper	a898c2d737	[X86] Remove two feature flags that covered sets of instructions that have no patterns or intrinsics. Since we don't check feature flags in the assembler parser for any instruction sets, these flags don't provide any value. This frees up 2 of the fully utilized feature flags. llvm-svn: 228282	2015-02-05 08:51:02 +00:00
Kevin Enderby	0d928a142b	Add support for the X86 secure guard extensions instructions in assembler (SGX). This allows assembling the two new instructions, encls and enclu for the SKX processor model. Note the diffs are a bigger than what might think, but to fit the new MRM_CF and MRM_D7 in things in the right places things had to be renumbered and shuffled down causing a bit more diffs. rdar://16228228 llvm-svn: 214460	2014-07-31 23:57:38 +00:00
