--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
Smaller testcase:
void __attribute__ ((noinline, noclone))
foo (signed char *__restrict dest, signed char *__restrict src,
signed char *__restrict cond, signed char bias, long n)
{
for (long i = 0; i < n; ++i)
{
signed char value = src[i] + bias;
if (cond[i])
{
dest[i * 4] = value;
dest[i * 4 + 1] = value;
dest[i * 4 + 2] = value;
dest[i * 4 + 3] = value;
}
}
}
for risc-v use -march=rv64gcv -mabi=lp64 -O3 -ftree-vectorize
-mrvv-vector-bits=scalable -fno-vect-cost-model
