            Bug ID: 27736
           Summary: Gdb really needs an enhanced assembly stepping mode
           Product: gdb

            Status: NEW
          Severity: normal

>>From https://bugzilla.redhat.com/show_bug.cgi?id=3D1859714 :

Gdb really needs an enhanced assembly stepping mode that will print,
not just the instructions themselves, but also the inputs and outputs.

For example, on POWER, if the current instruction is add r9, r1, r2:

(gdb) stepi
    # would print
<address expression>:     <previous instruction>
    r1 =3D 15 (0x0F)  r2 =3D 14 (0x0E)
<current address>:        add  r9, r1, r2
    r9 =3D 29 (0x1D)
<address expression>:     <next instruction>

(gdb)
