Subject: [PATCH] V4, patch #7: Use PADDI to add 34-bit constants
Date: Thu, 19 Sep 2019 00:13:00 -0000 [thread overview]
Message-ID: <20190919001255.GG28484@ibm-toto.the-meissners.org> (raw)
In-Reply-To: <20190918234214.GA27521@ibm-toto.the-meissners.org>
This patch now allows GCC to generate PADDI to add 34-bit constants.
I have done a bootstrap build with all of the patches applied, and there were
no regressions in the test suite. After posting these patches, I will start a
job to build each set of patches in turn just to make sure there are no extra
warnings.
Can I commit this patch to the trunk?

* config/rs6000/predicates.md (add_operand): Add support for
PADDI.
* config/rs6000/rs6000.md (add<mode>3): Add support for PADDI.
