27Subject: [PATCH] objdump relocation fixes for ARM disassembly

35Hello,
36
37objdump disassembly did not relocate correctly for the ARM processor. It seems
38that the test for triggering the INSN_HAS_RELOC flag was void (one test killed the other,
39since octets would always be zero) and all relocations would thus fail. I changed the test
40so the flag is set when we are about to disassemble an insn that the current relocation
41entry points to. I also changed objdump_print_addr to use the current relocation entry if
42the insn has such an entry. This causes the symbol printed to be correct for both external
43symbols (from the undefined section) and local symbols.
44
45This has only been tested for the ARM processor, but I don't think it should break other
46DISASSEMBLER_NEEDS_RELOCS processors either.

53 * objdump.c (disassemble_bytes): Fixed relocation check for
54 DISASSEMBLER_NEEDS_RELOCS platforms to properly trigger the
55 INSN_HAS_RELOC flag. Set the current relocation entry in
56 objdump_disasm_info to allow printing the proper symbol.
57 (objdump_print_addr): Use the relocation entry in
58 objdump_disasm_info to lookup the correct symbol for
59 DISASSEMBLER_NEEDS_RELOCS platforms.
