In a loop like this, I would recommend moving the "subs" instruction
further away from the branch that depends on it. For cores with in-order
execution, it does matter a fair bit, while it probably doesn't for cores
with out-of-order execution. Here, the ideal location probably is after
the two loads at the start. The same thing goes for all the other
functions in this patch.
Other than that, this looks ok.

Why not just do "ld1r {v28.4s}, [x9]" here instead, avoiding the
indirection via GPRs?
Other than that, I think this mostly looks reasonable.
Btw, for any assembly patches like these, it would be appreciated if you
can provide benchmarks from checkasm, e.g. "checkasm --test=hevc_pel
--bench=put_hevc" (or maybe just "--bench") and extract the relevant lines
for the functions that you've added/modified, and mention what system
you've benchmarked it on. You get the most useful benchmarks for
micro-tuning if you can enable userspace access to the timing registers
and configure with --disable-linux-perf.

This backs up values on the stack without decrementing the stack pointer,
i.e. storing it in the red zone. Whether this is supported depends on the
platform ABI. Linux and macOS have a 128 byte red zone on aarch64, while
Windows only has 16 bytes. So for portability, don't rely on a red zone at
all.
I.e., here please decrement the stack pointer like in a previous patch:
stp q8, q9, [sp, #-64]!
stp q10, q11, [sp, #32]
And inversely when restoring it.

In general, place the loop counter decrement somewhere else than exactly
before the branch that depends on the result. E.g. after the initial loads
is usually a good place, or between the st1/2 instructions and the
instructions that calculate the final output values.
The same goes probably for all places in all these patches.

Here are some stray unrelated whitespace changes.
Other than that, this patch looks mostly reasonable.

What does this "and" do here? Is it a case where the argument is "int",
while the upper bits of the register is undefined? In those cases, you're
best off by just using "w4", possibly "w4, uxtw" (or sxtw) instead of
manually doing such an "and" here.

Don't do consecutive decrements like this, but do one "stp ..., [sp,
#-48]!" followed by "stp ..., [sp, #16]" etc.

Fold the stack increment into ldp, like "ldp q12, q13, [sp], #128".
The same thing applies to all other functions in this patch too.

Oh, and another detail here. You don't need to back up and restore the
whole q8-q15 registers, it's enough to restore the lower 64 bits of it, so
you can do
stp d8, d9, [sp, #-32]
stp d10, d11, [sp, #16]
in this case.

based on armv9.

Thanks for clarifying that. When updating patches, please include those
benchmark numbers in the commit message, and mention the HW used for
testing there in the commit message.
And when tweaking patches, remember to update the benchmark numbers in the
commit message if the tweak changes the results notably.
The patchset is almost ok to be pushed, there's a couple issues left. I
was about to just fix up the last issues myself and push them, but patch 5
had a bit more issues than I wanted to fix silently.

This is missing a comma between "v17" and "v4" (here and in one other
place). This breaks compilation for macOS targets, where the assembler
(for historical reasons) has a separate way of handling macro arguments.
The same also goes for "v20 v24" in two places.

As mentioned in another follow-up reply, you don't need to back up and
restore all of q8-q15, only the lower half. This means that it's enough
to back up and restore d8-d15, which only takes half as much space.
I.e. here you'd have
+ stp d8, d9, [sp, #-32]!
+ stp d10, d11, [sp, #16]
instead, and for the full d8-d15 you'd have
+ stp d8, d9, [sp, #-64]!
+ stp d10, d11, [sp, #16]
+ stp d12, d13, [sp, #32]
+ stp d14, d15, [sp, #48]
The same goes for both of these places in this patch, and for a
number of places in patch 5/5.

Only need to back up 64 bytes, by backing up d8-d15. Also, the order
is quite weird here, why not keep them in e.g. linear order?

As mentioned already in the previous review - why do you back up and
restore xzr here? That's not necessary. Yes, you should keep the stack
16 byte aligned, but you can just leave an empty slot, and just do
"str x30, [sp, #-48]!" here, and vice versa with "ldr" instead of ldp
when restoring.
The same goes in all functions here.

Only need d8-d15, and weird register order here, and elsewhere.

FWIW, it's unusual to need an explicit sxtw instruction, but I guess
if you use it in the form "add x10, x4, #3" it might be needed.

Don't do consecutive stack pointer updates like this, but merge it
into one large stack decrement followed by positive offsets, like in
all the other cases of stp/ldp.

Don't do multiple stack decrements, don't needlessly store xzr here.
The same goes for all the other functions in this patch.

Hi, Martin,
Thanks for your comments.
I have now amended the unreasonable parts of ldp/stp that I have seen.
And I updated patch 3 and patch 5. (Although I have attached all 5 patches)
In addition, I thought that q8-q15 was required to be saved according to
the calling convention before, but later I confirmed that it is the
lower 64bit, thank you for reminding.
Please take a look. If there are some small mistakes, please correct
them directly. If there are still many problems, please remind me again,
thank you!

Thanks, this looks mostly good to me!
In patch 3, there was still one case of a missing comma between macro
arguments, that I fixed. I also included the checkasm benchmark numbers in
the commit messages - please remember to add them for future patches.
I'll push these patches later after a bit more testing, if that testing
doesn't show any further issues. Thanks!
