Bug ID: 102834
Summary: gcc.target/i386/avx512f-pr96891-3.c FAILs
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: ro at gcc dot gnu.org
CC: crazylht at gmail dot com
Target Milestone: ---
Target: i?86-pc-solaris2.11, x86_64-pc-solaris2.11
The gcc.target/i386/avx512f-pr96891-3.c test has been FAILing on 32-bit
Solaris/x86
since it was installed:
FAIL: gcc.target/i386/avx512f-pr96891-3.c scan-assembler-times (?n)vpcmp[bwdq][
\\\\t]*\\\\\$7 4
The pattern only occurs 3 times instead of the expected 4. Attaching the
assembler output for reference.

> 32-bit avx512f-pr96891-3.s
It relies on the existence of the pattern one_cmpldi2_doubleword, so that the
avx512bw_cmpv64qi3 and one_cmpldi2_doubleword will be combined to
avx512bw_cmpv64qi3 w/ adjustment of imm operand, but on 32-bit Solaris/x86
one_cmpldi2_doubleword is not existed.
(define_expand "one_cmpl<mode>2"
[(set (match_operand:SWIM1248s 0 "nonimmediate_operand")
(not:SWIM1248s (match_operand:SWIM1248s 1 "nonimmediate_operand")))]
(define_mode_iterator SWIM1248s
[(QI "TARGET_QIMODE_MATH")
(HI "TARGET_HIMODE_MATH")
SI (DI "TARGET_64BIT || (TARGET_STV && TARGET_SSE2)")])
mstv
Target Mask(STV) Save
Disable Scalar to Vector optimization pass transforming 64-bit integer
computations into a vector ones.
Guess stv is disabled on on 32-bit Solaris/x86, if that, the fail should be
expected and xfail should be added for 32-bit Solaris/x86

testsuite: i386: Fix gcc.target/i386/avx512f-pr96891-3.c on Solaris
[PR102834]
gcc.target/i386/avx512f-pr96891-3.c currently FAILs on 32-bit Solaris/x86:
FAIL: gcc.target/i386/avx512f-pr96891-3.c scan-assembler-times
(?n)vpcmp[bwdq][ \\\\t]*\\\\\$7 4
There are only 3 instances of the expected pattern because Solaris/x86
defaults to -mno-stv. Fixed by compiling with -mstv and
-mno-stackrealign. Tested on i386-pc-solaris2.11 and
x86_64-pc-linux-gnu.
