This issue can be reproduced with a few prebuilt files: https://martin.st/temp/profile/ Download those three files, build `llvm-cov` (on Linux or anywhere), and execute this: ``` $ llvm-cov show coverage_comments.cpp.exe -instr-profile coverage_comments.cpp.tmp.profdata ``` Before this breaking change, you'll get this: ``` error: C:/path/to/llvm-project/compiler-rt/test/profile/coverage_comments.cpp: No such file or directory warning: The file 'C:/path/to/llvm-project/compiler-rt/test/profile/coverage_comments.cpp' isn't covered. ``` After this change, you instead get this: ``` error: failed to load coverage: 'coverage_comments.cpp.exe': failed to uncompress data (zlib) ``` Can someone revert this change to get things back into working order? https://github.com/llvm/llvm-project/pull/111332 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
