(er, quickly checking ...)

(top-gdb) print $orig_eax
$1 = -1
(top-gdb) maint print raw-registers
...
  orig_eax     41   41    308       4  int             0xffffffff

Yep, of course you can.

What about save/restore?  Should it be saved/restored across an inferior 
function call?

Preserving existing behavior? :-^

So you'd like the mmx and sse registers excluded
(general corresponds to `info all-registers')?

Just give the word,
