* Retry^4 "[llvm-profdata] Add option to ingest filepaths from a file"Vedant Kumar2016-06-071-0/+9
| | | | | | | | | | Changes since the initial commit: - Use echo instead of printf. This should side-step the character escaping issues on Windows. Differential Revision: http://reviews.llvm.org/D20980 llvm-svn: 272068

| | | | | | | | | This reverts commit r271953. It's still breaking on Windows, though the list initialization issue is fixed: http://bb.pgr.jp/builders/ninja-clang-i686-msc19-R/builds/3751 llvm-svn: 271963
* Retry^2 "[llvm-profdata] Add option to ingest filepaths from a file"Vedant Kumar2016-06-061-0/+9
| | | | | | | | | | | | | Changes since the initial commit: - Normalize file paths read from the file to prevent Windows path separators from escaping parts of the path. - Since we need to store the normalized file paths in WeightedFile, don't do tricky things to keep the source MemoryBuffer alive. - Don't use list-initialization for a std::string in WeightedFile.

* [llvm-profdata] Revert r271709 and the 3 subsequent commits - the codeChandler Carruth2016-06-041-9/+0
| | | | | | | | | | | | | | | | | | | | and/or tests aren't working on Windows currently. There seems to be some problem with quoting the file paths. I don't understand the test structure here or the code well enough to try to come up with a way to correctly handle paths with back slashes in them, and this has caused the Windows builds to be failing for 7 hours now, so I'm reverting the whole thing to bring them back to life. Sorry for the disruption, but a couple of these were bug fixes anyways that can be folded into a fresh commit. Reverts the following patches: r271756: Clean up the way we create the input filenames buffer (NFC) r271748: Fix use-after-free from discarded MemoryBuffer (NFC) r271710: Fix option description (NFC) r271709: Add option to ingest filepaths from a file llvm-svn: 271760

* [Profiling] Add a -sparse mode to llvm-profdata mergeVedant Kumar2016-01-291-0/+6
| | | | | | | | | | Add an option to llvm-profdata merge for writing out sparse indexed profiles. These profiles omit InstrProfRecords for functions which are never executed. Differential Revision: http://reviews.llvm.org/D16727 llvm-svn: 259258
* [llvm-profdata] Add support for weighted merge of profile data (2nd try)Nathan Slingerland2015-12-151-1/+40
| | | | | | | | | | | | | | | | | | | | Summary: This change adds support for specifying a weight when merging profile data with the llvm-profdata tool. Weights are specified by using the --weighted-input=<weight>,<filename> option. Input files not specified with this option (normal positional list after options) are given a default weight of 1. Adding support for arbitrary weighting of input profile data allows for relative importance to be placed on the input data from multiple training runs. Both sampled and instrumented profiles are supported.

| | | | | | | | This reverts commit b7250858d96b8ce567681214273ac0e62713c661. Reverting in order to investigate Windows test failure. llvm-svn: 254687
* [llvm-profdata] Add support for weighted merge of profile dataNathan Slingerland2015-12-041-1/+5
| | | | | | | | | | | | | | | | | | This change adds support for an optional weight when merging profile data with the llvm-profdata tool. Weights are specified by adding an option ':<weight>' suffix to the input file names. Adding support for arbitrary weighting of input profile data allows for relative importance to be placed on the input data from multiple training runs. Both sampled and instrumented profiles are supported. Reviewers: dnovillo, bogner, davidxl Subscribers: llvm-commits Differential Revision: http://reviews.llvm.org/D14547 llvm-svn: 254669
* Fix sphinx-build error when building documentation.Xinliang David Li2015-11-241-16/+10
| | | | | | | Consolidate the description of -binary/-text option description to avoid duplicate ID error by sphinux-build. llvm-svn: 254018
* [PGO] Add --text option for llvm-profdata show|merge commandsXinliang David Li2015-11-231-1/+18
| | | | | | | | | | | | | | The new option is similar to the SampleProfile dump option. - dump raw/indexed format into text profile format - merge the profile and output into text profile format. Note that Value Profiling data text format is not yet designed. That functionality will be added later. Differential Revision: http://reviews.llvm.org/D14894 llvm-svn: 253913

| | | | | | | These links seem broken on llvm.org/docs. Change them to use the sphinx-recommended style to see if that helps. llvm-svn: 232001

* PGO: llvm-profdata: tool for merging profilesDuncan P. N. Exon Smith2014-02-171-0/+29
Introducing llvm-profdata, a tool for merging profile data generated by PGO instrumentation in clang. - The name indicates a file extension of <name>.profdata. Eventually profile data output by clang should be changed to that extension. - llvm-profdata merges two profiles. However, the name is more general, since it will likely pick up more tasks (such as summarizing a single profile). - llvm-profdata parses the current text-based format, but will be updated once we settle on a binary format. <rdar://problem/15949645> llvm-svn: 201535
