Subject: RE: [PATCH 5/8]AArch64 aarch64: Make existing V2HF be usable.
Date: Fri, 11 Nov 2022 14:39:54 +0000 [thread overview]

Hi,

Done.

They are, but they weren't meant to be in this patch. They belong in a separate FP16 series that
I won't get to finish for GCC 13 due not being able to finish writing all the tests. I have moved them
to that patch series though.
While the addp patch series has been killed, this patch is still good standalone and improves codegen
as shown in the updated testcase.
Bootstrapped Regtested on aarch64-none-linux-gnu and no issues.
Ok for master?
Thanks,
Tamar
