Subject: [PATCH-3, rs6000] Change mode and insn condition for scalar insert exp instruction
Date: Wed, 4 Jan 2023 14:17:01 +0800 [thread overview]
Message-ID: <f82d5de1-31fd-f700-f633-1aeb15b39e1c@linux.ibm.com> (raw)
Hi,
This patch changes the mode of exponent to GPR in scalar insert exp
pattern, as the exponent can be put into a 32-bit register. Also the
condition check is changed from TARGET_64BIT to TARGET_POWERPC64.
The test cases are modified according to the changes of expand pattern.
Bootstrapped and tested on powerpc64-linux BE and LE with no regressions.
Is this okay for trunk? Any recommendations? Thanks a lot.
Gui Haochen
ChangeLog
2023-01-03 Haochen Gui <guihaoc@linux.ibm.com>
gcc/
* config/rs6000/rs6000-builtins.def
(__builtin_vsx_scalar_insert_exp): Replace bif-pattern from xsiexpdp
to xsiexpdp_di.
(__builtin_vsx_scalar_insert_exp_dp): Replace bif-pattern from
xsiexpdpf to xsiexpdpf_di.
* config/rs6000/vsx.md (xsiexpdp): Rename to...
(xsiexpdp_<mode>): ..., set the mode of second operand to GPR and
replace TARGET_64BIT with TARGET_POWERPC64.
(xsiexpdpf): Rename to...
(xsiexpdpf_<mode>): ..., set the mode of second operand to GPR and
replace TARGET_64BIT with TARGET_POWERPC64.
gcc/testsuite/
* gcc.target/powerpc/bfp/scalar-insert-exp-0.c: Replace lp64 check
with has_arch_ppc64.
