* [profile] Remove another unneeded field in raw profile readerXinliang David Li2016-05-061-1/+0
| | | | | | | DataValueSize is now removed. The change is consolidated with previous raw version bump. llvm-svn: 268703
* [Profile] Raw profile header clean upXinliang David Li2016-05-051-2/+1
| | | | | | Remove dead ValueDataBegin field in raw header. llvm-svn: 268602
* Reapply (2x) "[PGO] Fix name encoding for ObjC-like functions"Vedant Kumar2016-03-281-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | Function names in ObjC can have spaces in them. This interacts poorly with name compression, which uses spaces to separate PGO names. Fix the issue by using a different separator and update a test. I chose "\01" as the separator because 1) it's non-printable, 2) we strip it from PGO names, and 3) it's the next natural choice once "\00" is discarded (that one's overloaded). What's changed since the original commit? - I fixed up the covmap-V2 binary format tests using a linux VM. - I weakened the CHECK lines in instrprof-comdat.h to account for the fact that there have been bugfixes to clang coverage. These will be fixed up in a follow-up. - I added an assert to make sure we don't get bitten by this again. - I constructed the c-general.profraw file without name compression enabled to appease some bots.

* Revert "Reapply "[PGO] Fix name encoding for ObjC-like functions""Vedant Kumar2016-03-281-1/+1
| | | | | | | This reverts commit r264641 to investigate why c-general.test is failing on the bots. llvm-svn: 264643

* [PGO] Enable compression in pgo instrumentationXinliang David Li2016-02-081-9/+7
| | | | | | | | | | | | This reduces sizes of instrumented object files, final binaries, process images, and raw profile data. The format of the indexed profile data remain the same. Differential Revision: http://reviews.llvm.org/D16388 llvm-svn: 260117
* [PGO] Value profiling supportBetul Buyukkurt2015-11-181-2/+11
| | | | | | | | | This change introduces an instrumentation intrinsic instruction for value profiling purposes, the lowering of the instrumentation intrinsic and raw reader updates. The raw profile data files for llvm-profdata testing are updated. llvm-svn: 253484
* InstrProf: Check pointer size in raw profileDuncan P. N. Exon Smith2014-03-231-0/+42
Since the profile can come from 32-bit machines, we need to check the pointer size. Change the magic number to facilitate this. Adds tests for reading 32-bit and 64-bit binaries (both big- and little-endian). The tests write a binary using printf in RUN lines (like raw-magic-but-no-header.test). Assuming the bots don't complain, this seems like a better way forward for testing RawInstrProfReader than committing binary files. <rdar://problem/16400648> llvm-svn: 204557
