Rong Xu	9c6f1538cc	[PGO] Change profile use cc1 option to handle IR level profiles ... This patch changes cc1 option for PGO profile use from -fprofile-instr-use=<path> to -fprofile-instrument-use-path=<path>. -fprofile-instr-use=<path> is now a driver only option. In addition to decouple the cc1 option from the driver level option, this patch also enables IR level profile use. cc1 option handling now reads the profile header and sets CodeGenOpt ProfileUse (valid values are {None, Clang, LLVM} -- this is a common enum for -fprofile-instrument={}, for the profile instrumentation), and invoke the pipeline to enable the respective PGO use pass.

Justin Bogner	534f14abe7	test: Use llvm-profdata merge in Profile tests ... In preparation for using a binary format for instrumentation based profiling, explicitly treat the test inputs as text and transform them before running. This will allow us to leave the checked in files in human readable format once the instrumentation format is binary. No functional change. llvm-svn: 206509	2014-04-17 22:49:06 +00:00
Justin Bogner	e2ef2a09ef	CodeGen: Emit warnings for out of date profile data during PGO ... This adds a warning that triggers when profile data doesn't match for the source that's being compiled with -fprofile-instr-use=. This fires only once per translation unit, as warning on every mismatched function would be quite noisy. llvm-svn: 206322	2014-04-15 21:22:35 +00:00
Justin Bogner	ffaa2330b9	test: Regenerate profile data for PGO tests ... Some of this data had gotten out of date, so we weren't quite testing what we thought we were. This also moves the outdated data test to its own file to simplify regenerating the test data. llvm-svn: 203546	2014-03-11 06:49:34 +00:00
