This is an enhancement to LLVM Source-Based Code Coverage in clang to track how many times individual branch-generating conditions are taken (evaluate to TRUE) and not taken (evaluate to FALSE). Individual conditions may comprise larger boolean expressions using boolean logical operators. This functionality is very similar to what is supported by GCOV except that it is very closely anchored to the ASTs. Differential Revision: https://reviews.llvm.org/D84467 |

README
These are tests for instrumentation based profiling. This specifically means the -fprofile-instr-generate and -fprofile-instr-use driver flags. Tests in this directory should usually test both: - the generation of instrumentation (-fprofile-instr-generate), and - the use of profile data from instrumented runs (-fprofile-instr-use). In order to test -fprofile-instr-use without actually running an instrumented program, .profdata files are checked into Inputs/. The input source files must include a main function such that building with -fprofile-instr-generate and running the resulting program generates the same .profdata file that is consumed by the tests for -fprofile-instr-use. Even tests that only check -fprofile-instr-use should include such a main function, so that profile data can be regenerated as the .profdata file format evolves.
