Hi Richard,
Here's the split off complex add.
Bootstrapped Regtested on aarch64-none-linux-gnu and no issues.
Checked with armv8-a+sve2+fp16 and no issues. Note that due to a mid-end
limitation SLP for SVE currently fails for some permutes. The tests have these
marked as XFAIL.
Matching tests

No, sounds good to me.
Thanks,

Hi Richard,
Do you object to me splitting off complex add and addressing your remaining
feedback later when the rewrite of mul and fma are done.
Thanks,

Hi All,
This adds implementation for the optabs for complex operations. With this the
following C code:
void f90 (float complex a[restrict N], float complex b[restrict N],
float complex c[restrict N])
{
for (int i=0; i < N; i++)
c[i] = a[i] + (b[i] * I);
}
generates
