Revert part of r227437 as it was unnecessary. Thanks to echristo for pointing this out. llvm-svn: 227897 2015-02-03 07:58:54 +08:00			`; RUN: llc < %s -march=x86 -mattr=-sse2 \| FileCheck %s`
Custom lower the memory barrier instructions and add support for lowering without sse2. Add a couple of new testcases. Fixes a few libgomp tests and latent bugs. Remove a few todos. llvm-svn: 109078 2010-07-22 10:48:34 +08:00

Cleanup a few tests on sse4a machines and FileCheckize along the way. llvm-svn: 227437 2015-01-29 21:31:32 +08:00			`; CHECK: lock`
Last batch of test conversions to new atomic instructions. llvm-svn: 140585 2011-09-27 08:17:29 +08:00			`fence seq_cst`
