Show current assembly instruction in GDB

Question

I\'m doing some assembly-level debugging in GDB. Is there a way to get GDB to show me the current assembly instruction in the same way that it shows the current source line?

Answer 1

Setting the following option:

set  disassemble-next-line on
show disassemble-next-line

Will give you results that look like this:

(gdb) stepi
0x000002ce in ResetISR () at startup_gcc.c:245
245 {
   0x000002cc : 80 b5   push    {r7, lr}
=> 0x000002ce : 82 b0   sub sp, #8
   0x000002d0 : 00 af   add r7, sp, #0
(gdb) stepi
0x000002d0  245 {
   0x000002cc : 80 b5   push    {r7, lr}
   0x000002ce : 82 b0   sub sp, #8
=> 0x000002d0 : 00 af   add r7, sp, #0
