2016-05-24Add FIXMEs to all derived classes of std::error_category.Peter Collingbourne1-0/+3
This helps make clear that we're moving away from std::error_code. Differential Revision: http://reviews.llvm.org/D20592 llvm-svn: 270604
2016-03-03Use LineLocation instead of CallsiteLocation to index callsite profile.Dehao Chen1-15/+2
Summary: With discriminator, LineLocation can uniquely identify a callsite without the need to specifying callee name. Remove Callee function name from the key, and put it in the value (FunctionSamples).

2015-12-16[PGO] Handle and report overflow during profile merge for all types of dataNathan Slingerland1-0/+2
Summary: Surface counter overflow when merging profile data. Merging still occurs on overflow but counts saturate to the maximum representable value. Overflow is reported to the user.

2015-11-19SamplePGO - Tweak debugging output for function samples. NFC.Diego Novillo1-9/+24
llvm-svn: 253612
2015-11-19SamplePGO - Sort samples by source location when emitting as text.Diego Novillo1-5/+8
When dumping function samples or writing them out as text format, it helps if the samples are emitted sorted by source location. The sorting of the maps is a bit slow, so we only do it on demand. llvm-svn: 253568
2015-11-17SamplePGO - Move debug/dump function bodies out of header files. NFC.Diego Novillo1-0/+43
No point polluting the header declarations with debugging code. llvm-svn: 253361
2015-11-13SamplePGO - Add dump routines for LineLocation, SampleRecord and FunctionSamplesDiego Novillo1-19/+16

2015-11-13[llvm-profdata] Add check for text profile formats and improve error ↵Nathan Slingerland1-4/+4
reporting (2nd try) Summary: This change addresses two possible instances of user error / confusion when merging sampled profile data. Previously any input that didn't match the raw or processed instrumented format would automatically be interpreted as instrumented profile text format data. No error would be reported during the merge. Example: If foo-sampled.profdata and bar-sampled.profdata are binary sampled profiles: Old behavior: $ llvm-profdata merge foo-sampled.profdata bar-sampled.profdata -output foobar-sampled.profdata $ llvm-profdata show -sample foobar-sampled.profdata error: foobar-sampled.profdata:1: Expected 'mangled_name:NUM:NUM', found lprofi This change adds basic checks for valid input data when assuming text input. It also makes error messages related to file format validity more specific about the assumbed profile data type. New behavior: $ llvm-profdata merge foo-sampled.profdata bar-sampled.profdata -o foobar-sampled.profdata error: foo.profdata: Unrecognized instrumentation profile encoding format Perhaps you forgot to use the -sample option?

2015-11-12SamplePGO - Move FunctionSamples::print() to a better location. NFC.Diego Novillo1-0/+32
The class is declared in SampleProf.h, so a better home for this is SampleProf.cpp. llvm-svn: 252915
2015-10-13Sample profiles - Add a name table to the binary encoding.Diego Novillo1-0/+4
Binary encoded profiles used to encode all function names inline at every reference. This is clearly suboptimal in terms of space. This patch fixes this by adding a name table to the header of the file. llvm-svn: 250241
2015-09-17GCC AutoFDO profile reader - Initial support.Diego Novillo1-0/+2
This adds enough machinery to support reading simple GCC AutoFDO profiles. It now supports reading flat profiles (no function calls). Subsequent patches will add support for: - Inlined calls (in particular, the inline call stack is not traversed to accumulate samples). - Working sets and modules. These are used mostly for GCC's LIPO optimizations, so they're not needed in LLVM atm. I'm not sure that we will ever need them. For now, I've if0'd around the calls. The patch also adds support in GCOV.h for gcov version V704 (generated by GCC's profile conversion tool). llvm-svn: 247874
2015-06-23Revert r240137 (Fixed/added namespace ending comments using clang-tidy. NFC)Alexander Kornienko1-1/+1
Apparently, the style needs to be agreed upon first. llvm-svn: 240390
2015-06-19Fixed/added namespace ending comments using clang-tidy. NFCAlexander Kornienko1-1/+1
The patch is generated using this command: tools/clang/tools/extra/clang-tidy/tool/run-clang-tidy.py -fix \ -checks=-*,llvm-namespace-comment -header-filter='llvm/.*|clang/.*' \ llvm/lib/ Thanks to Eugene Kosov for the original patch! llvm-svn: 240137
2014-11-01Add show and merge tools for sample PGO profiles.Diego Novillo1-0/+2
Summary: This patch extends the 'show' and 'merge' commands in llvm-profdata to handle sample PGO formats. Using the 'merge' command it is now possible to convert one sample PGO format to another. The only format that is currently not working is 'gcc'. I still need to implement support for it in lib/ProfileData. The changes in the sample profile support classes are needed for the merge operation. Reviewers: bogner Subscribers: llvm-commits Differential Revision: http://reviews.llvm.org/D6065 llvm-svn: 221032
2014-10-30Add profile writing capabilities for sampling profiles.Diego Novillo1-0/+49
Summary: This patch finishes up support for handling sampling profiles in both text and binary formats. The new binary format uses uleb128 encoding to represent numeric values. This makes profiles files about 25% smaller. The profile writer class can write profiles in the existing text and the new binary format. In subsequent patches, I will add the capability to read (and perhaps write) profiles in the gcov format used by GCC. Additionally, I will be adding support in llvm-profdata to manipulate sampling profiles. There was a bit of refactoring needed to separate some code that was in the reader files, but is actually common to both the reader and writer. The new test checks that reading the same profile encoded as text or raw, produces the same results.
