We don't assign counters for implicit Decls, but we were emitting code to increment the (non-existent) counters and adding empty counter lists in the output. This fixes the checks in assignRegionCounters and emitInstrumentationData to do the right thing, and adds an assert for the pathological case of emitting zero counters. llvm-svn: 207203 |

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.
