Subject: [PATCH 0/3] OpenMP SIMD routines
Date: Tue, 9 Aug 2022 14:23:47 +0100 [thread overview]
Message-ID: <cover.1660051134.git.ams@codesourcery.com> (raw)
This patch series implements OpenMP "simd" routines for amdgcn, and also
adds support for "simd inbranch" routines for amdgcn, x86_64, and
aarch64 (probably, I can't easily test it).
I can approve patch 2 myself, but it depends on patch 1 so I include it
here for context and completeness.
I first tried to use "mask_mode = DImode", for amdgcn, but that does not
produce great results because it ends up generating code to turn the
mask into a vector and then back into the exact same mask, so I have
settled on "mask_mode = VOIDmode", for now (in fact that uses fewer
argument registers in many cases, so maybe it's better anyway).
Additionally, I find that the x86_64 truth vectors cannot always be
converted to the mask types specified by the backend, so I have pulled
that code out completely.
Therefore, this patch includes only "mask_mode == VOIDmode" support,
but remains a step forward towards full SIMD clone support.
I have not included dump-scans in the testcases for aarch64, but the
testcases will still test correctness. The aarch64 maintainers can very
easily add those scans if they choose. No other architecture has
backend support for the clones at this time.
OK for mainline (patches 1 & 3)?
Thanks
Andrew
