It isn't in git (since it is a generated file). --enable-maintainer-mode creates it. And configure should warn if it isn't there that you need --enable-maintainer-mode (it is there in a release tar ball of course). I guess it is slightly confusing if you once configured with --enable-maintainer-mode and then configure the same tree without and in between dwarf.h gets updated. Then it indeed doesn't get updated. Sorry about that. > PS: all 172 tests passed in sparc64-linux-gnu Great. Thanks for testing! Cheers, Mark
Latest version of dwarflint?
I found the dwarflint and locstats tools in the ‘dwarf ‘ branch of elfutils. https://sourceware.org/elfutils/DwarfLint Any plans of merging this into main branch? I get following error from locstats: error: .debug_info: DIE 0x3f10fc: dwarf_getlocation_addr: invalid DWARF This error is reported on DW_OP_GNU_entry_value in DWARF location list. Any newer version of these tools which can handle DWARF5 ops such as DW_OP_GNU_entry-value? Thanks Ananth
