The AArch64 parts of this look fine to me, and based on benchmarking of the
patch they are low risk for high reward (and other targets have had a
vectorized copysign for a while without issue).

Hi All,
It seems the entry in config/aarch64/aarch64-builtins.c isn't needed, as such
I've simplified the patch
and the changelog.
Ok

Hi All,
This is a slight modification of the earlier patch (Using a different constant
in the mask creation.)

Kind Regards,

Subject: [PATCH][GCC][Aarch64] Add vectoriz
Hi All,
This patch vectorizes the copysign builtin for AArch64
similar to how it is done for Arm.
AArch64 now generates:
...
.L4:
ldr q1, [x6, x3]
add w4, w4, 1
ldr q0, [x5, x3]
cmp w4, w7
bif v1.16b, v2.16b, v3.16b
fmulv0.2
