Subject: [PATCH], Patch #5 of 10, Make -mpcrel default for -mcpu=future
Date: Wed, 14 Aug 2019 22:23:00 -0000 [thread overview]
Message-ID: <20190814221510.GE16578@ibm-toto.the-meissners.org> (raw)
In-Reply-To: <20190814205732.GA11956@ibm-toto.the-meissners.org>
This patch changes the default for -mcpu=future to turn on pc-relative
addressing by default.
I have built each of the patches in turn on a little endian power8 system doing
a bootstrap and make check. There were no regressions. Can I check this patch
into the trunk once the previous patches are checked in?

* config/rs6000/rs6000-cpus.def (ISA_FUTURE_MASKS_SERVER): Enable
pc-relative support by default on 'future' systems.
