Subject: [PATCH v4, rs6000] Change mode and insn condition for VSX scalar extract/insert instructions
Date: Mon, 7 Nov 2022 14:45:05 +0800 [thread overview]
Message-ID: <91d596d0-e4ca-f60f-4fe0-d96e35d62de2@linux.ibm.com> (raw)
Hi,
For scalar extract/insert instructions, exponent field can be stored in a
32-bit register. So this patch changes the mode of exponent field from DI to
SI. So these instructions can be generated in a 32-bit environment. The patch
removes TARGET_64BIT check for these instructiions.
The instructions using DI registers can be invoked with -mpowerpc64 in a
32-bit environment. The patch changes insn condition from TARGET_64BIT to
TARGET_POWERPC64 for those instructions.
This patch also changes prototypes and catagories of relevant built-ins and
effective target checks of test cases.
Compared to last version, main changes are to set catagories of relevant
built-ins from power9-64 to power9 and remove some unnecessary test cases.
Last version: https://gcc.gnu.org/pipermail/gcc-patches/2022-September/601196.html
Bootstrapped and tested on powerpc64-linux BE and LE with no regressions.
Is this okay for trunk? Any recommendations? Thanks a lot.
