            Bug ID: 104726
           Summary: gcc.target/i386/pr104551.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/pr104551.c test FAILs on Solaris/x86 (32 and 64-bit) since
its introduction:

+FAIL: gcc.target/i386/pr104551.c execution test

Thread 2 received signal SIGILL, Illegal instruction.
[Switching to Thread 1 (LWP 1)]
0x080510ff in main ()
(gdb) bt
#0  0x080510ff in main ()
(gdb) x/i $pc
=> 0x80510ff <main+15>: vmovd  %eax,%xmm0

The machine in question indeed lacks AVX2 support.  I guess the test needs to
use
avx2-check.h to handle this.

A patch

Hi Rainer, can you try this on your solaris system? We don't have such platform
to confirm it works.

I'll install it if it passes, or you can directly push it as an obvious fix.

Removing the eff. target avx2 is wrong, that makes sure the assembler can
support that isa, which you still need

--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Also, the builtin at the start of main compiled with -mavx2 is risky, there
could be avx2 insns e.g. in the prologue. avx2-check.h is the usual way

Thanks for pointing it out, updated accordingly.

Hi Rainer, sorry for previous mistake, can you try the updated one?
