[PATCH] D80833: [CodeView] Add full repro to LF_BUILDINFO record

aganea added a comment.

When using `clang-cl`, this code should set it to the right format, on any platform: https://github.com/llvm/llvm-project/blob/master/clang/lib/Driver/Driver.cpp#L1071
However maybe something else happens on big endian architectures?

@uweigand Would you mind running the first `clang-cl` command with -### see what target is being used? This is what I'm seeing on my Ubuntu machine. Note the `x86_64-pc-windows-msvc19.11.0` triple. If using plain `clang -c b.cpp` then `x86_64-unknown-linux-gnu` is used instead.

  aganea at PC:/mnt/f/llvm-project$ cat b.cpp
  int A;
  int foo() {
    return A * 20;
  }
  int main() {
    return foo();
  }
