...ut I found "e_machine" is defined somewhere in MCAssembler(My compiler uses binutils as assembler) . Although I make some hacks to pass this checking, I still get other errors. So my problem is whether llvm-cov has to work with MCAssembler and is it possible to do it with binutils?

...quot; and the error was "Failed to load coverage: No object file for requested architecture." I think I should add my arch information to somewhere(maybe an llvm-cov support list?) but I don't know where to add these information. Can someone give me some suggestions? Best Regards, Ruobin.

...overageMappingReader.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?

...ill 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 solution for the first point). Where should I place __llvm_prf_* sections? Is it ok to put them into .rodata section?

...ort', these two assembly files became the same but other assembly files differed(A_Linux = A_Windows, B_Linux != B_Windows). I cannot figure out the reason and could you give me some advice why this happened and what sort algorithm should I use to get exactly same assembly files?

...ause 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 which may help. We are using coverage tool for a new target so when building compiler-rt, we use InstrProfilingPlatformOther.c Best, Ruobin

...these functions are supported by glibc but I cannot bulid glibc with clang/llvm(configure gave me an error “These critical programs are missing or too old: compiler”). So I want to know how can I compile glibc with clang/llvm or are there some WIP patches to help me with this requirement? Thanks, Ruobin.

I’m working on enabling llvm-cov for my compiler which is a totally new arch with a libc.a built from newlib. I successfully built compiler-rt but when I typed the command ` clang...
