            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.
