--- Comment #6 from Bernd Edlinger <bernd.edlinger at hotmail dot de> ---
just wanted to add that the patch in comment#2
does not fix this similar test case:
struct lock_chain {
char x;
unsigned short base;
} __attribute((packed));
struct lock_chain * foo (struct lock_chain *chain)
{
int i;
for (i = 0; i < 100; i++)
{
chain[i+1].base = chain[i].base;
}
return chain;
}
foo:
@ Function supports interworking.
@ args = 0, pretend = 0, frame = 0
@ frame_needed = 0, uses_anonymous_args = 0
@ link register save eliminated.
ldrh r2, [r0, #1] <- unaligned
add r1, r0, #300
and ip, r2, #255
add r1, r1, #3
lsr r2, r2, #8
add r3, r0, #3
.L2:
strb ip, [r3, #1]
strb r2, [r3, #2]
add r3, r3, #3
cmp r3, r1
bne .L2
bx lr
