Bug ID: 30834
Summary: improve disassembly output for call and branch
instructions
Product: binutils
Version: 2.42 (HEAD)
Status: NEW
Severity: normal
Priority: P2
Component: gprofng
Assignee: vladimir.mezentsev at oracle dot com
Reporter: vladimir.mezentsev at oracle dot com
Target Milestone: ---
gprofng only displays the hexadecimal address in call and jump instructions:
% gprofng display src -dis main ./a.out | egrep 'call|jmp'
[23] 401eca: call 0x1f68
[24] 401ee6: call 0xfffffffffffffafa
[26] 401ef9: jmp 0x13f
[28] 401f0d: call 0x3a2f
[29] 401f27: call 0xfffffffffffffab9
Need to display the function name in the calling instruction, and the absolute
and relative address in the branch instruction.
For example, the output of gdb and er_src is:
% gdb -batch -ex 'file a.out' -ex 'disassemble main' 2>&1 | egrep 'call|jmp'
0x0000000000401eca <+8>: call 0x403e32 <bfd_init>
0x0000000000401ee6 <+36>: call 0x4019e0 <printf@plt>
0x0000000000401ef9 <+55>: jmp 0x402038 <main+374>
0x0000000000401f0d <+75>: call 0x40593c <bfd_openr>
0x0000000000401f27 <+101>: call 0x4019e0 <printf@plt>
% er_src -dis main a.out | egrep 'call|jmp'
[23] 401eca: call bfd_init [ 0x403e32, .+0x1f68 ]
[24] 401ee6: call .-0x506 [ 0x4019e0 ]
[26] 401ef9: jmp .+0x13f [ 0x402038 ]
[28] 401f0d: call bfd_openr [ 0x40593c, .+0x3a2f ]
[29] 401f27: call .-0x547 [ 0x4019e0 ]
