Add test triples to fix win32 failures. Revert workaround from r161292. I don't have a win32 system to test, so hopefully I got them all fixed here. llvm-svn: 161519

Refactor and check "onlyReadsMemory" before optimizing builtins. This patch is mostly just refactoring a bunch of copy-and-pasted code, but it also adds a check that the call instructions are readnone or readonly. That check was already present for sin, cos, sqrt, log2, and exp2 calls, but it was missing for the rest of the builtins being handled in this code. llvm-svn: 161282

Convert ARM tests to FileCheck for PR5307. llvm-svn: 89593

Convert CodeGen/*/*.ll tests to use the new CHECK-LABEL for easier debugging. No functionality change and all tests pass after conversion. This was done with the following sed invocation to catch label lines demarking function boundaries: sed -i '' "s/^;\( *\)\([A-Z0-9_]*\):\( *\)test\([A-Za-z0-9_-]*\):\( *\)$/;\1\2-LABEL:\3test\4:\5/g" test/CodeGen/*/*.ll which was written conservatively to avoid false positives rather than false negatives. I scanned through all the changes and everything looks correct. llvm-svn: 186258

; CORTEXA8-LABEL: test:
Inflate register classes after coalescing. Coalescing can remove copy-like instructions with sub-register operands that constrained the register class. Examples are: x86: GR32_ABCD:sub_8bit_hi -> GR32 arm: DPR_VFP2:ssub0 -> DPR Recompute the register class of any virtual registers that are used by less instructions after coalescing. This affects code generation for the Cortex-A8 where we use NEON instructions for f32 operations, c.f. fp_convert.ll: vadd.f32 d16, d1, d0 vcvt.s32.f32 d0, d16 The register allocator is now free to use d16 for the temporary, and that comes first in the allocation order because it doesn't interfere with any s-registers. llvm-svn: 137133

; CORTEXA9-LABEL: test:
Avoid write-after-write issue hazards for Cortex-A9. Add a avoidWriteAfterWrite() target hook to identify register classes that suffer from write-after-write hazards. For those register classes, try to avoid writing the same register in two consecutive instructions. This is currently disabled by default. We should not spill to avoid hazards! The command line flag -avoid-waw-hazard can be used to enable waw avoidance. llvm-svn: 129772
