Stephen Lin	f799e3f944	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	2013-07-13 20:38:47 +00:00
Rafael Espindola	29dda21e96	Remove arm_apcscc from the test files. It is the default and doing this ... matches what llvm-gcc and clang now produce. llvm-svn: 106221	2010-06-17 15:18:27 +00:00
Bob Wilson	9be7200b08	Last week we were generating code with duplicate induction variables in this ... test, but the problem seems to have gone away today. Add a check to make sure it doesn't come back. llvm-svn: 96277	2010-02-15 21:56:40 +00:00
Bob Wilson	01abf8fc2f	Besides removing phi cycles that reduce to a single value, also remove dead ... phi cycles. Adjust a few tests to keep dead instructions from being optimized away. This (together with my previous change for phi cycles) fixes Apple radar 7627077. llvm-svn: 96057	2010-02-13 00:31:44 +00:00
Bob Wilson	0827e040e0	Add a new pass on machine instructions to optimize away PHI cycles that ... reduce down to a single value. InstCombine already does this transformation but DAG legalization may introduce new opportunities. This has turned out to be important for ARM where 64-bit values are split up during type legalization: InstCombine is not able to remove the PHI cycles on the 64-bit values but the separate 32-bit values can be optimized. I measured the compile time impact of this (running llc on 176.gcc) and it was not significant. llvm-svn: 95951	2010-02-12 01:30:21 +00:00
