Subject: [PATCH,rs6000] Add built-in function support for Power9 byte instructions
Date: Mon, 14 Nov 2016 23:43:00 -0000 [thread overview]
Message-ID: <ab3a654d-f151-a37c-3c52-5c667f19dc34@linux.vnet.ibm.com> (raw)
This patch adds built-in function support for the new setb, cmprb, and
cmpeqb Power9 instructions.
The patch has been bootstrapped and tested on
powerpc64le-unknown-linux and powerpc-unknown-linux (big-endian, with
both -m32 and -m64 target options) with no regresions.
Is this ok for the trunk?
