[llvm-dev] llvm-objdump: failed to parse debug information

[Robinson, Paul via llvm-dev]

Agreed.  However, these don’t look like reasons for llvm-objdump to choke.

Hmm, those look like function's that've been optimized out & that's the expected DWARF for them - but the verify stuff was implemented by Apple folks focussing on the MachO debug info distribution model that doesn't have that quirk. Would be good to fix the verifier to not hiccup on that sort of expected linked ELFine DWARF. (Adrian, etc?)
