------- Comment #4 from pinskia at gcc dot gnu dot org 2006-09-09 05:48 -------
For x86, 3.4.0 produces:
movl 4(%esp), %edx
movsbl a+1(%edx),%eax
movsbl b+1(%edx),%edx
addl %edx, %eax
ret
While 4.0.0 produced:
movl 4(%esp), %edx
incl %edx
movsbl a(%edx),%eax
movsbl b(%edx),%edx
addl %edx, %eax
ret
(Note this is also not really a target issue as PPC can be helped by this also
by having a+1 and b+1 and no need for an extra increment of 1 to the argument).
