Subject: [PATCH] RISC-V: Support RVV VLA SLP
From: Juzhe-Zhong
This patch enables basic VLA SLP auto-vectorization.
Consider this following case:
void
f (uint8_t *restrict a, uint8_t *restrict b)
{
for (int i = 0; i < 100; ++i)
{
a[i * 8 + 0] = b[i * 8 + 7] + 1;
a[i * 8 + 1] = b[i * 8 + 7] + 2;
a[i * 8 + 2] = b[i * 8
addiw a5,a5,3
> sb a5,799(a0)
> ret
Ideally, this scalar codes should be able to vectorized like aarch64.
