As of r313998, this workflow no longer works: cd <build-dir> ./bin/llvm-lit <src>/llvm/tools/clang/test/CoverageMapping I get: llvm-lit: /Users/vk/src/llvm.org-coverage-braces/llvm/tools/clang/test/lit.cfg.py:97: note: using clang: '/Volumes/Builds/llvm.org-coverage-braces-RA/bin/clang' llvm-lit: /Users/vk/src/llvm.org-coverage-braces/llvm/utils/lit/lit/TestingConfig.py:101: fatal: unable to parse config f...

...eof(uint8_t), Padding}}; ``` This helped us successfully passed some small cases(not know for sure whether the coverage result is true, but we can see coverage report). But when we added more cases, `llvm-cov show -arch=xxx ...` gave us an assertion when entering fuction ` loadFunctionRecord ` in CoverageMapping.cpp. The OrigFuncName is empty when inserting into FunctionNames. Seems the llvm-cov cannot find a function name. I think it's because we didn't construct a correct default.profraw. So how data is laid out in default.profraw when doing profiling? Any help will be appreciated. A small tip...

...()->e_machine, Type);”. But I think it makes sense ELF file reader get nothing because my compiler doesn’t write these information. It seems I have to find somewhere(maybe an ELF file writer) to write e_machine so my reader will read this. But I have no idea where to write it now. 2. In CoverageMapping.cpp, there is a checking “OF->getArch() != Triple(Arch).getArch()” and it makes an error if not equal. “OF->getArch” will go into a switch/case and the code enters the default branch which returns an UnknownArch. I hacked the code to make default branch return Triple::XXXX(only a temporary so...

New error was “Failed to load coverage: No coverage data found” since the compiler cannot get NamesSection(at loadBinaryFormat in CoverageMappingReader.cpp). I thought it was my ldscript problem because I put __llvm_prf_names, __llvm_prf_cnts, __llvm_prf_data and __llvm_prf_vnds inside .rodata section. Compiler checked .rodata but not things inside .rodata. What’s the right position to put these 4 __llvm_prf_* sections? Best, Ruobin. 发件人:...
