* Revert "CodeGen: Use a binary format for instrumentation based profiling"Justin Bogner2014-03-127-0/+0
| | | | | | | | | I've clearly done something wrong with how to get this to link correctly. Reverting for now. This reverts commit r203711. llvm-svn: 203712
* CodeGen: Use a binary format for instrumentation based profilingJustin Bogner2014-03-127-0/+0
| | | | | | | | This updates CodeGenPGO to use the ProfileDataReader introduced to llvm in r203703 and the new API for writing out the profile introduced to compiler-rt in r203710. llvm-svn: 203711
* PGO: appease the bots after r203592Duncan P. N. Exon Smith2014-03-111-1/+1

* PGO: Clarify the testing READMEDuncan P. N. Exon Smith2014-03-111-8/+16

* PGO: Scale large counters down to 32-bitsDuncan P. N. Exon Smith2014-03-112-0/+59
| | | | | | | | | PGO counters are 64-bit and branch weights are 32-bit. Scale them down when necessary, instead of just taking the lower 32 bits. <rdar://problem/16276448> llvm-svn: 203592
* test: Regenerate profile data for PGO testsJustin Bogner2014-03-118-58/+56
| | | | | | | | Some of this data had gotten out of date, so we weren't quite testing what we thought we were. This also moves the outdated data test to its own file to simplify regenerating the test data.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
* test: Give instrumentation based profiling tests their own directoryJustin Bogner2014-03-1111-0/+1032
These tests are logically related, but they're spread about several different CodeGen directories. Consolidate them in one place to make them easier to manage. llvm-svn: 203541
