Prefer object over notype symbols when disassembling
Changing objdump disassembly output like this always requires some testsuite changes, with the avr and x64_64 changes simply due to picking up better symbols, the whole point of the patch. The mips changes are due to mips-sgi-irix changing STT_NOTYPE symbols to STT_OBJECT, which objdump now chooses in preference to script symbols. The problem is that objdump looks at the first symbol in the section being disassembled, and if object type, just dumps out bytes rather than disassembling. This results in new failures: FAIL: JAL overflow 2 FAIL: undefined weak symbol overflow FAIL: undefined weak symbol overflow (n32) FAIL: undefined weak symbol overflow (n64) So for mips-sgi-irix function symbols really do need to be function type. I fixed a few more than just the required minimum to avoid the above test fails. binutils/ * objdump.c (compare_section): New static var. (compare_symbols): Sort by current section only. Don't access symbol name out of bounds when checking for file symbols. Sort section symbols and object symbols. (find_symbol_for_address): Remove bogus debugging and section symbol test.
