Hi All, While working on some recent patches for x32 support, I ran into an unpleasant limitation the LLVM eco-system has with testing DWARF emission. We currently have several approaches, neither of which is great: 1. llvm-dwarfdump: the best approach when it works. But unfortunately lib/DebugInfo supports only a (small) subset of DWARF. Tricky sections like debug_frame aren't supported. 2.
