Before this patch the '_raw_spin_lock_irqsave' and 'update_rq_clock' operands
were appearing just as hexadecimal numbers:
update_blocked_averages /proc/kcore
│ push %r12
│ push %rbx
│ and $0xfffffffffffffff0,%rsp
│ sub $0x40,%rsp
│ add -0x662cac00(,%rdi,8),%rax
│ mov %rax,%rbx
│ mov %rax,%rdi
│ mov %rax,0x38(%rsp)
│ → callq _raw_spin_lock_irqsave
│ mov %rbx,%rdi
│ mov %rax,0x30(%rsp)
│ → callq update_rq_clock
│ mov 0x8d0(%rbx),%rax
│ lea 0x8d0(%rbx),%r11
To check that all is right one can always use the 'o' hotkey and see
the original objdump -dS output, that for this case is:
update_blocked_averages /proc/kcore
│ffffffff990d5489: push %r12
│ffffffff990d548b: push %rbx
│ffffffff990d548c: and $0xfffffffffffffff0,%rsp
│ffffffff990d5490: sub $0x40,%rsp
│ffffffff990d5494: add -0x662cac00(,%rdi,8),%rax
│ffffffff990d549c: mov %rax,%rbx
│ffffffff990d549f: mov %rax,%rdi
│ffffffff990d54a2: mov %rax,0x38(%rsp)
│ffffffff990d54a7: → callq 0xffffffff997eb7a0
│ffffffff990d54ac: mov %rbx,%rdi
│ffffffff990d54af: mov %rax,0x30(%rsp)
│ffffffff990d54b4: → callq 0xffffffff990c7720
│ffffffff990d54b9: mov 0x8d0(%rbx),%rax
│ffffffff990d54c0: lea 0x8d0(%rbx),%r11
Use the 'h' hotkey to see a list of available hotkeys.
More work needed to cover operands for other instructions, such as 'mov',
that can resolve variable names, etc.
