gdb) help rs
Step program backward until it reaches the beginning of another source line.
Argument N means do this N times (or till program stops for another reason).
(gdb) help rsi
Step backward exactly one instruction.
Argument N means do this N times (or till program stops for another reason).
(gdb) help rn
Step program backward, proceeding through subroutine calls.
Like the "reverse-step" command as long as subroutine calls do not happen;
when they do, the call is treated as one instruction.
Argument N means do this N times (or till program stops for another reason).
(gdb) help rni
Step backward one instruction, but proceed through called subroutines.
Argument N means do this N times (or till program stops for another reason).

reverse debugging is implemented elsewhere? For elf? Remote debugging?
online evaluation/call?
gdb is quite good IMHO.
