            Bug ID: 44397
           Summary: MC produces a R_X86_64_PC32, gas produces a
                    R_X86_64_PLT32
           Product: libraries
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: MC
          Assignee: unassignedbugs at nondot.org

Given

        jne foo
        .long foo - .

MC produces two R_X86_64_PC32 relocations. The gnu assembler produces a
R_X86_64_PLT32 for the first one and a R_X86_64_PC32 to the second one.

The advantage of producing a R_X86_64_PLT32 for branches is that the linker
doesn't have to enforce pointer equality in the same way it has to do for
R_X86_64_PC32.

The corresponding bug in the gnu assembler is
