* Coverage: add HasCodeBefore flag to a mapping region.Alex Lorenz2014-08-041-6/+10
| | | | | | | | | This flag will be used by the coverage tool to help compute the execution counts for each line in a source file. Differential Revision: http://reviews.llvm.org/D4746 llvm-svn: 214740
* Use std::unique_ptr to make the ownership explicit.Rafael Espindola2014-07-311-2/+2

* Coverage: improve efficiency of the counter propagation to the expansion ↵Alex Lorenz2014-07-291-8/+12

* coverage: remove empty mapping regionsAlex Lorenz2014-07-251-3/+0
| | | | | | | | This patch removes the empty coverage mapping regions. Those regions were produced by clang's old mapping region generation algorithm, but the new algorithm doesn't generate them. llvm-svn: 213981

* Add code coverage mapping data, reader, and writer.Alex Lorenz2014-07-241-0/+482
This patch implements the data structures, the reader and the writers for the new code coverage mapping system. The new code coverage mapping system uses the instrumentation based profiling to provide code coverage analysis. llvm-svn: 213910
