Hi,
This patch adds the memory operand of MVE masked stores as input operands to
mimic the 'partial' writes, to prevent erroneous write-after-write
optimizations as described in the PR.
Regression tested on arm-none-eabi for armv8.1-m.main+mve.fp.
OK for trunk?

Hi,
This patch surrounds the scalar operand of the MVE vcmp patterns with a
vec_duplicate to ensure both operands of the comparision operator have the same
(vector) mode.
Regression tested on arm-none-eabi. Is this OK for trunk? And a backport to GCC
12?

Hey Kyrill,

Hi,
This patch teaches the AArch64 backend that AES instructions with a XOR and
zero operands can be simplified by replacing the operands of the AES with XOR's
thus eliminating the XOR. This is OK because the AES instruction XORs the input
operands.
This will improve code-generation when deali
Hi,
This patch teaches the AArch64 backend that the AESE and AESD unspecs are
commutative (which correspond to the vaeseq_u8 and vaesdq_u8 intrinsics). This
improves register allocation around their corresponding instructions avoiding
unnecessary moves.
For instance, with the old patterns code
Hi,
This patch series aims to improve codegen for the AArch64 AES instructions by
doing two things.
The first is to make the AES unspecs commutative and by consequence make the
corresponding intrinsics commutative, since the instructions themselves are
commutative in the input.
This will impro

Hi,
The address printing for LDP/STP patterns that don't use parallel was not
working properly when dealing with a post-index addressing mode. The post-index
address printing uses the mode's size to determine the post-index immediate.
