            Bug ID: 41947
           Summary: Dynamic zero-sized and non-function symbols should be
                    included in disassembly
           Product: tools
           Version: trunk
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: llvm-objdump
          Assignee: unassignedbugs at nondot.org
          Reporter: jh7370.2008 at my.bristol.ac.uk

For some reason, when adding dynamic symbols to the set of symbols to be used
in disassembly, only non-zero-sized function symbols are added. This does not
match GNU's behaviour, and is also inconsistent with the static symbol
behaviour. We should remove this restriction. It doesn't give us anything.

Example output for an object with two dynamic symbols (one non-function, and
one zero-sized):

objdump.exe -d stripped.o

stripped.o:     file format elf64-x86-64


Disassembly of section .text:

0000000000001000 <zero_sized>:
    1000:       90                      nop

0000000000001001 <not_func>:
    1001:       90

llvm-objdump.exe -d stripped.o

stripped.o:     file format elf64-x86-64


Disassembly of section .text:

0000000000001000 .text:
    1000:       90                      nop
    1001:       90
