Huh.
The trunk code is vectorized all the way:
ptrue p1.h, vl8 ; set p1.h to 8 wide
ptrue p0.b, all ; set p0.b to all ones
ld2h {z2.h - z3.h}, p1/z, [x1] ; load the 8x2 vector into z2/z3
ld2h {z0.h - z1.h}, p1/z, [x2] ; load the 8x2 vector into z0/z1
ld2h {z16.h - z17.h}, p1/z, [x0] ; load the 8x2 vector into z16/17
fmul z6.h, z0.h, z3.h ; z6 = z0 * z3
movprfx z7, z16 ; z7 = z16
fmla z7.h, p0/m, z0.h, z2.h ; z7+=z0*z2
fmla z6.h, p0/m, z1.h, z2.h ; z6 += z1*z2
movprfx z4, z7 ; z4 = z7
fmls z4.h, p0/m, z1.h, z3.h ; z4 -= z1*z3
fadd z5.h, z6.h, z17.h ; z5 = z6 + z17
st2h {z4.h - z5.h}, p1, [x0] ; store the 8x2 vector into x0
note the way ld2 works is the first element goes into the first vector, second
element goes into the second vector, the 3rd element goes into the first
vector, the 4th element goes into the second vector.
So this is optimized all the way. Knowing the lower limit of the size of the
vectors will be 128 byte (or 64 half floats) so 8 half floats will always fit
into one vector just fine.
So this is vectorized all the way such that it is unrolled even.

Note st2 does the opposite of ld2 while doing the storing of the vector.

it is easier to understand what is going wrong with:

{
for (int i =0 ; i != 4; i++)

}
Oh you don't need SVE either because it was added for normal SIMD in ARMv8.3-a.
Confirmed.

The testcases added for this case does not actually test that complex fma was
done.
The testcases were added in r11-6697. The aarch64 patterns were added with
r11-6734 .

Yes.
For x86 side, AVX512-FP16 have vfcmaddcph/fcmaddcph for _Float16
cmla/conj_cmla, the issue is found when we're working on supporting that.
NOTE: slp pattern match for .COMPLEX_MUL is ok.
#include<complex.h>
void
foo (_Complex float* a, _Complex float* b, _Complex float *c)
{
for (int i =0 ; i != 4; i++)
a[i] = b[i] * c[i];
}

Yes the SLP tree layout was changed in GCC 12 so the detection for FMA and FMS
are broken. I have them fixed in my local trunk but am working on a related
patch before I post them.
Mine.

Actually I'll just push the fix for this out now.
> The testcases added for this case does not actually test that complex fma was done.
yes, the way we were originally testing depended on target support for these
patterns, which made it nearly impossible to write testcases as different arm
options would change the support across AArch64, SVE, MVE, AArch32, SVE2.
This has been changed to output detection regardless of targets so the
testcases can now be properly written. Should be addressed in the patch I'm
pushing out.

Author: Tamar Christina <tamar.christina@arm.com>
Date: Fri Oct 29 12:45:41 2021 +0100
middle-end: Update the Arm complex numbers auto-vec detection to the new
format of the SLP tree.
The layout of the SLP tree has changed in GCC 12 which
broke the detection of complex FMA and FMS.
This patch updates the detection to the new tree shape
and by necessity merges the complex MUL and FMA detection
into one.
This does not yet address the wrong code-gen PR which I
will fix in a different patch as that needs backporting.

middle-end: Add target independent tests for Arm complex numbers
vectorization.
This beefs up the complex numbers vectorization testsuite
and adds target independent checks next to the target
dependent ones.
This allows regressions to the detection code to be found
when running on any target, not just aarch64.
