* [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
* Update documentation for llvm-profdata.Diego Novillo2015-05-281-0/+30
| | | | | | | These options have been present for a while, but I had never updated the documentation. Fixed. llvm-svn: 238511
* docs: Try to fix a couple of internal links in the llvm-profdata manualJustin Bogner2015-03-121-4/+4
| | | | | | | 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
