(Not to block this patch)
Seems like this trick can be done even with less than perf
Hi,
For the following test-case:
int16x8_t foo(int16_t x, int16_t y)
{
return (int16x8_t) { x, y, x, y, x, y, x, y };
}
Code gen at -O3:
foo:
dupv0.8h, w0
ins v0.h[1], w1
ins v0.h[3], w1
ins v0.h[5], w1
ins v0.h[7], w1
ret
