When the DWARF address size is 32-bit, but the host machine is 64-bit, objdump fails to spot base addresses specified in the .debug_ranges and .debug_loc lists. As an example, here is the output when dumping an example .debug_ranges section with the pre-patched objdump: Contents of the .debug_ranges section: Offset Begin End 00000000 ffffffff 00000004 (start > end) 00000000 00000000 00000004 00000000 ffffffff 00000008 (start > end) 00000000 00000000 00000004 00000000 <End of list> And this is what the same section looks like when dumped with the patched version of objdump: Contents of the .debug_ranges section: Offset Begin End 00000000 ffffffff 00000004 (base address) 00000000 00000004 00000008 00000000 ffffffff 00000008 (base address) 00000000 00000008 0000000c 00000000 <End of list> binutils/ChangeLog: * dwarf.c (is_max_address): New function. (display_loc_list): Remove out of date comment, use is_max_address. (display_debug_ranges): Likewise. binutils/testsuite/ChangeLog: * binutils-all/objdump.exp: Add test for .debug_ranges decode. * binutils-all/dw2-ranges.S: New file. * binutils-all/dw2-ranges.W: New file. |
