huh a compiler built with that patch gives:
L4:
slwi r2,r9,1
addi r9,r9,1
sthx r0,r2,r11
bdnz L4
Also pulling the load manually out loop also produce the same asm as I just produced:
unsigned short *q;
#define NOSB 10
int last;
void h1()
{
int i;
unsigned short *q1 = q;
for (i=0;i<last+NOSB;i++)
{
q1[i] = 0;
}
}
