It isn't very wise to pass an assembly file to the compiler and tell it to compile as a C file and hope that the compiler recognizes it as assembly instead. Simply don't mark the file as C and CMake will recognize the rest. This was attempted earlier in https://reviews.llvm.org/D85706, but reverted due to architecture issues on Apple. Subsequent digging revealed a similar change was done earlier for libunwind in https://reviews.llvm.org/rGb780df052dd2b246a760d00e00f7de9ebdab9d09. Afterwards workarounds were added for MinGW and Apple: * https://reviews.llvm.org/rGb780df052dd2b246a760d00e00f7de9ebdab9d09 * https://reviews.llvm.org/rGd4ded05ba851304b26a437896bc3962ef56f62cb The workarounds in libunwind and compiler-rt are unified and comments added pointing to each other. The workaround is updated to only be used for MinGW for CMake versions before 3.17, which fixed the issue (https://gitlab.kitware.com/cmake/cmake/-/merge_requests/4287). Additionally fixed Clang not being passed as the assembly compiler for compiler-rt runtime build.
