Before this patch, when compiling an IR file (eg the .llvmbc section from an object file compiled with -Xclang -fembed-bitcode=all) and profile data was passed in using the -fprofile-instrument-use-path flag, there would be no error printed (as the previous implementation relied on the error getting caught again in the constructor of CodeGenModule which isn't called when -x ir is set). This patch moves the error checking directly to where the error is caught originally rather than failing silently in setPGOUseInstrumentor and waiting to catch it in CodeGenModule to print diagnostic information to the user. Regression test added. Reviewed By: xur, mtrofin Differential Revision: https://reviews.llvm.org/D132991 |

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.
