[PATCH] D49426: [DEBUG_INFO] fix .loc directives emitted for missing prologues

[David Blaikie via Phabricator via llvm-commits]

dblaikie added a comment.

So GAS does the same thing as Clang's integrated assembler currently (pre-patch) and that behavior is problematic for GDB and LLDB? (only for LLDB) so the difference is that the assembly clang generates includes these zero-address-length locations, but GCC doesn't?

What's the problematic cases/behavior in the debuggers or other DWARF consumers?
