InstrProf: Add some unit tests for CoverageMapping The llvm-level tests for coverage mapping need a binary input file, which means they're hard to understand, hard to update, and it's difficult to add new ones. By adding some unit tests that build up the coverage data structures in C++, we can write more meaningful and targeted tests. llvm-svn: 228084

InstrProf: Don't combine expansion regions with code regions This was leading to duplicate counts when a code region happened to overlap exactly with an expansion. The combining behaviour only makes sense for code regions. llvm-svn: 229723

[Profiling] Add a -sparse mode to llvm-profdata merge 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

InstrProf: Support for value profiling in the indexed profile format Add support to the indexed instrprof reader and writer for the format that will be used for value profiling. Patch by Betul Buyukkurt, with minor modifications. llvm-svn: 248833

InstrProf: Strip filename prefixes from the names we display for coverage For consumers of coverage data, any filename prefixes we store in the profile data are just noise. Strip this prefix if it exists. llvm-svn: 236558

InstrProf: Add some unit tests for CoverageMapping The llvm-level tests for coverage mapping need a binary input file, which means they're hard to understand, hard to update, and it's difficult to add new ones. By adding some unit tests that build up the coverage data structures in C++, we can write more meaningful and targeted tests. llvm-svn: 228084
