--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Confirmed, Here is a much shorter testcase and not related to loops either:
void bar(int i)
{
char A[10];
g(A);
f(A[i]);
}
--- CUT ---
Before:
bar:
stp x29, x30, [sp, -64]!
add x29, sp, 0
stp x19, x20, [sp, 16]
add x19, x29, 48
mov w20, w0
mov x0, x19
bl g
ldrb w0, [x19, w20, sxtw]
bl f
ldp x19, x20, [sp, 16]
ldp x29, x30, [sp], 64
ret
After:
bar:
stp x29, x30, [sp, -48]!
add x29, sp, 0
str x19, [sp, 16]
mov w19, w0
add x0, x29, 32
bl g
add x0, x29, 48
add x19, x0, x19, sxtw
ldrb w0, [x19, -16]
bl f
ldr x19, [sp, 16]
ldp x29, x30, [sp], 48
ret
