I'm not aware of such a tool, but could be written using the "xed" tool in the xed distribution. However I would trust xed over objdump, it is used widely in Intel tools with likely far more testing than binutils > 4b8506 jz 0x4b84d0 <perf_evsel__enable+0x70> 74 c8 je > 4b84d0 <perf_evsel__enable+0x70> > 4b84d0 add $0x1, %r14 > add $0x1,%r14 > 4b84d4 cmp %r14d, %ebx > cmp %r14d,%ebx > 4b84d7 jle 0x4b8530 <perf_evsel__enable+0xd0> > jle 4b8530 <perf_evsel__enable+0xd0> > 4b8530 add $0x1, %r12 > add $0x1,%r12 > 4b8534 cmp %r12d, %r13d > cmp %r12d,%r13d > 4b8537 jnle 0x4b84c2 <perf_evsel__enable+0x62> 7f 89 jg > 4b84c2 <perf_evsel__enable+0x62> > 4b84c2 xor %r14d, %r14d > xor %r14d,%r14d > 4b84c5 test %ebx, %ebx > test %ebx,%ebx > 4b84c7 jnle 0x4b84d9 <perf_evsel__enable+0x79> 7f 10 jg > 4b84d9 <perf_evsel__enable+0x79> > 4b84d9 movq 0x90(%r15), %rax 49 8b 87 90 00 00 00 > mov 0x90(%r15),%rax > 4b84e0 mov %r12, %rdx > mov %r12,%rdx > 4b84e3 mov %r14, %rcx > mov %r14,%rcx > 4b84e6 mov $0x2400, %esi > mov $0x2400,%esi > 4b84eb imulq (%rax), %rdx 48 0f af 10 > imul (%rax),%rdx > 4b84ef imulq 0x8(%rax), %rcx 48 0f af 48 08 > imul 0x8(%rax),%rcx > 4b84f4 add %rdx, %rax > add %rdx,%rax > 4b84f7 xor %edx, %edx > xor %edx,%edx > 4b84f9 movl 0x18(%rcx,%rax,1), %edi 8b 7c 01 18 > mov 0x18(%rcx,%rax,1),%edi > 4b84fd xor %eax, %eax > xor %eax,%eax > 4b84ff callq 0x42d990 <ioctl@plt> > callq 42d990 <ioctl@plt> > 4b8504 test %eax, %eax > test %eax,%eax > 4b8506 jz 0x4b84d0 <perf_evsel__enable+0x70> 74 c8 je > 4b84d0 <perf_evsel__enable+0x70> Yes all the differences are ok. It's just synonyms of the instructions. -Andi
