            Bug ID: 18154
           Summary: llvm-objdump should have a option to start disassembly
                    at a specified symbol name
           Product: tools
           Version: trunk
          Hardware: PC
                OS: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: llvm-dis
          Assignee: unassignedbugs at nondot.org

Rafael Espíndola <rafael.espindola at gmail.com> asked me to creating a bug about
this missing feature llvm-objdump.  It came from the test case I created in:

[llvm] r196432 - Fix a bug in darwin's 32-bit X86 handling of evaluating
fixups.

Where if I had an option like darwin's otool(1) -p option I could have created
more readable test case with something like:

otool -tv -p bug /tmp/x.o
/tmp/x.o:
(__TEXT,__text) section
bug:
01020f55        movl    $0x0, 0x1537564

Because this specific bug required the offset to the item to be relocated
needing to be more than 24 bits to trigger the bug, it takes a long time to do
the disassembly if it starts a the beginning of the section.
