* test: https://gcc.godbolt.org/z/WfxGE3q9r
```
void foo (int *restrict y, int *restrict x, int *restrict indices, int n) {
for (int k = 0; k < 10; k++)
for (int i = 0; i < n; i++) {
y[i + k * M] = y[i + k* M] + 1;
y[i + k * (M+1)] = indices[i] + 2;
}
}
```
* When I add option **-Rpass-analysis=loop-vectorize**, it reports **<source>:8:22: remark: loop not vectorized**，but in the final output assemble, we get **sve** assemble code as following:
```
.LBB0_2: // =>This Inner Loop Header: Depth=1
ld1w { z0.s }, p0/z, [x2, x9, lsl #2]
add z0.s, z0.s, #2 // =0x2
st1w { z0.s }, p0, [x0, x9, lsl #2]
add x9, x9, x10
whilelo p0.s, x9, x8
b.mi .LBB0_2
```
