* [llvm-cov] Track function and instantiation coverage separatelyVedant Kumar2016-09-191-0/+12
| | | | | | | | | | | | | | | | | | | | These are distinct statistics which are useful to look at separately. Example: say you have a template function "foo" with 5 instantiations and only 3 of them are covered. Then this contributes (1/1) to the total function coverage and (3/5) to the total instantiation coverage. I.e, the old "Function Coverage" column has been renamed to "Instantiation Coverage", and the new "Function Coverage" aggregates information from the various instantiations of a function. One benefit of making this switch is that the Line and Region coverage columns will start making sense. Let's continue the example and assume that the 5 instantiations of "foo" cover {2, 4, 6, 8, 10} out of 10 lines respectively. The new line coverage for "foo" is (10/10), not (30/50). The old scenario got confusing because we'd report that there were more lines in a file than what was actually possible. llvm-svn: 281875

* llvm-cov: Simplify coverage reports, fixing PR22575 in the processJustin Bogner2015-02-141-25/+0
| | | | | | | | | | | | | | PR22575 occurred because we were unsafely storing references into a std::vector. If the vector moved because it grew, we'd be left iterating through garbage memory. This avoids the issue by simplifying the logic to gather coverage information as we go, rather than storing it and iterating over it. I'm relying on the existing tests showing that this is semantically NFC, since it's difficult to hit the issue this fixes without relatively large covered programs. llvm-svn: 229215
* llvm-cov: Use the number of executed functions for the function coverage metric.Alex Lorenz2014-09-301-5/+6
| | | | | | | | This commit fixes llvm-cov's function coverage metric by using the number of executed functions instead of the number of fully covered functions. Differential Revision: http://reviews.llvm.org/D5196 llvm-svn: 218672
* llvm-cov: Disentangle the coverage data logic from the display (NFC)Justin Bogner2014-09-201-1/+1
| | | | | | | | | | This splits the logic for actually looking up coverage information from the logic that displays it. These were tangled rather thoroughly so this change is a bit large, but it mostly consists of moving things around. The coverage lookup logic itself now lives in the library, rather than being spread between the library and the tool. llvm-svn: 218184
* llvm-cov: Rename MappingRegion to coverage::CountedRegion (NFC)Justin Bogner2014-09-091-13/+13
| | | | | | | This name was too similar to CoverageMappingRegion, and the type really belongs in the coverage library anyway. llvm-svn: 217416
* llvm-cov: Remove dead codeJustin Bogner2014-09-081-1/+1
| | | | | | | FunctionCoverageMapping::PrettyName was from a version of the tool during review, and isn't actually used currently. llvm-svn: 217398

clang's pgo. This commit expands llvm-cov's functionality by adding support for a new code coverage tool that uses LLVM's coverage mapping format and clang's instrumentation based profiling. The gcov compatible tool can be invoked by supplying the 'gcov' command as the first argument, or by modifying the tool's name to end with 'gcov'.
