            Bug ID: 41341
           Summary: llvm-objdump -d --line-numbers omits function name
           Product: tools
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: llvm-objdump
          Assignee: unassignedbugs at nondot.org
          Reporter: rupprecht at google.com
                CC: llvm-bugs at lists.llvm.org

llvm-objdump does not include the function name when disassembling with -l
(--line-numbers). I'm not sure whether or not this is desired/intentional.

$ cat foo.c
int foo() {
  return 5;
}
$ clang -g -c foo.c -o foo.o
$ objdump -l -d foo.o

foo.o:     file format elf64-x86-64


Disassembly of section .text:

0000000000000000 <foo>:
foo():  <--------- this line is missing below
/tmp/foo.c:1
   0:   55                      push   %rbp
   1:   48 89 e5                mov    %rsp,%rbp
/tmp/foo.c:2
   4:   b8 05 00 00 00          mov    $0x5,%eax
   9:   5d                      pop    %rbp
   a:   c3                      retq

$ llvm-objdump -l -d foo.o

foo.o:  file format ELF64-x86-64

Disassembly of section .text:
0000000000000000 foo:
; /tmp/foo.c:1
       0:       55      pushq   %rbp
       1:       48 89 e5        movq    %rsp, %rbp
; /tmp/foo.c:2
       4:       b8 05 00 00 00  movl    $5, %eax
       9:       5d      popq    %rbp
       a:       c3      retq
