We recently had a QEMU decodetree hackathon at our org focusing on moving
instructions to decodetree specification. I have consolidated the patches
generated out of this effort in this series. Though I have done a round
of review on all of them, might share some more review comments later.
The checkpatch.pl script emits false error for a couple of patches which
are of the following nature :
TRANS(STWAT, do_st_atomic, DEF_MEMOP(MO_UL))
static bool trans_LDAT(DisasContext *ctx, arg_LDAT *a)
^
I see this happening in the last pointer argument in function
definitions after macros (like TRANS(..) in this case).
Richard, Peter, Stefan,
Could you please advise if it would be okay to have the above false
positive in the patches ?
Hi Chao,
I was wondering if you would be able to advise a way forward for this
checkpatch issue ? TIA.
Gitlab CI: https://gitlab.com/rathc/qemu/-/pipelines/2540725424
Please note that check-python-tox and migration-compat-aarch64 from CI
fails in the upstream master branch as seen in the following:

Hi Glenn,
If possible, would you like to have a look at this series when you get a
chance ? TIA.
Hi Chinmay,
First, I'd like to thank you and everyone that worked on this for their
efforts! This seems like one of those tasks that everyone knows is
needed but everyone would rather work on other more interesting things
(myself included). I would like to take a look at this series when I
get the chance. I do have a lot on my plate right now, but hopefully I
can get to it in the next week or so.
Thanks,
Glenn
Sure Glenn, thanks !
