            Bug ID: 32049
           Summary: objdump --disassemble=functionName --reloc includes
                    relocations from previous function
           Product: binutils
           Version: 2.38
            Status: UNCONFIRMED
          Severity: minor
          Priority: P2
         Component: binutils
          Assignee: unassigned at sourceware dot org
          Reporter: streetster at gmail dot com
  Target Milestone: ---

Created attachment 15659
  --> https://sourceware.org/bugzilla/attachment.cgi?id=15659&action=edit
example object file

This is the output when disassembling the attached 'target.o' file. The object
has multiple functions, but we are only interested in one of them. There are 3
relocations included (0x4, 0xa0, 0xf0) that do not apply to the function being
disassembled - I don't think they should be included in the output.


$ mips-linux-gnu-objdump --disassemble=eMessageNextGyouMaxGet --reloc target.o

target.o:     file format elf32-tradlittlemips

The behaviour is the same on binutils 2.42.
