Prefetch has a MemOperand now. FileCheckize a test. This finishes up 8460971. llvm-svn: 119848

Add test for r146163. llvm-svn: 146167

; RUN: llc < %s -march=x86 -mattr=+avx | FileCheck %s
Fix PRFCHW test on non-x86 builds - 'prefetch' intrinsics are only lowered when SSE is available. On non-X86 builds, 'generic' CPU is used and stops lowering any prefetch intrinsics. llvm-svn: 178046

Attempt to fix llvm-ppc64-linux2 buildbot failure by adding -march=x86 to SLM test. llvm-svn: 190958

Enabling 3DNow! prefetch instruction for a few AMD processors: bobcat, jaguar, bulldozer and piledriver. Support for the instruction itself seems to have already been added in r178040. Differential Revision: http://llvm-reviews.chandlerc.com/D1933 llvm-svn: 192828

Implement x86 support for @llvm.prefetch. It corresponds to prefetcht{0|1|2} and prefetchnta instructions. llvm-svn: 48042

Add one more argument to the prefetch intrinsic to indicate whether it's a data or instruction cache access. Update the targets to match it and also teach autoupgrade. llvm-svn: 132976
