--- Comment #5 from David Blaikie <dblaikie at gmail dot com> --- Just a quick +1 to Comment #2 - consumers shouldn't rely on the presence of .debug_aranges, or them being complete (DWARF doesn't require/guarantee this - and Clang doesn't emit aranges by default, for instance). Each contribution to .debug_aranges says which CU it covers and any CUs not covered should be parsed/assumed to contain things covering other addresses. Ideally parsing CUs lightly (just enough to get their CU ranges) should be fairly cheap - cheap enough to be worth doing so to avoid/save producers having to emit all the extra/duplicate data into .debug_aranges that's already covered by CU ranges. It'd be nice if Rust could revert/avoid emitting these aranges, like Clang does. -- You are receiving this mail because: You are on the CC list for the bug.
