            Bug ID: 108730
           Summary: gcc.target/powerpc/bfp/scalar-test-neg-8.c fails on
                    power 9 BE
           Product: gcc
           Version: 13.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: seurer at gcc dot gnu.org
  Target Milestone: ---

make  -k check-gcc RUNTESTFLAGS="--target_board=unix'{-m32,-m64}'
bfp.exp=gcc.target/powerpc/bfp/scalar-test-neg-8.c"

This fails on power 9 (only) and fails for trunk as well as gcc 12, 11, and 10.
 Previously it was always unsupported.

--- Comment #1 from Kewen Lin <linkw at gcc dot gnu.org> ---
The bif builtin_vsx_scalar_test_neg_qp is guarded with ieee128-hw, which
requires -m64, so the test case needs lp64 effective target.

  if (TARGET_FLOAT128_HW && !TARGET_64BIT)
    {
      if ((rs6000_isa_flags_explicit & OPTION_MASK_FLOAT128_HW) != 0)
        error ("%qs requires %qs", "%<-mfloat128-hardware%>", "-m64");

      rs6000_isa_flags &= ~OPTION_MASK_FLOAT128_HW;
    }

    testsuite: Adjust scalar-test-neg-8.c with lp64 [PR108730]

    The built-in function scalar_test_neg_qp is under stanza
    ieee128-hw, that is TARGET_FLOAT128_HW.  Since we don't
    have float128 hardware support on 32-bit as follows:

    if (TARGET_FLOAT128_HW && !TARGET_64BIT)
      {
        if ((rs6000_isa_flags_explicit & OPTION_MASK_FLOAT128_HW) != 0)
          error ("%qs requires %qs", "%<-mfloat128-hardware%>", "-m64");
        rs6000_isa_flags &= ~OPTION_MASK_FLOAT128_HW;
      }

    So adjust the case with lp64 effective target accordingly.

Should be fixed on trunk.
