Rong Xu a0afc3e162 llvm-profdata] Handle the cases of overlapping input file and output file ... Currently llvm-profdata does not expect the same file name for the input profile and the output profile. >llvm-profdata merge A.profraw B.profraw -o B.profraw The above command runs successfully but the resulted B.profraw is not correct. This patch fixes the issue by moving the initialization of writer after loading the profile. For the show command, the following will report a confusing error of "Empty raw profile file": >llvm-profdata show B.profraw -o B.profraw It's harder to fix as we need to output something before loading the input profile. I don't think that a fix for this is worth the effort. I just make the error explicit for the show command.
