            Bug ID: 104725
           Summary: g++.target/i386/pr35513-1.C etc. FAIL
           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: hjl.tools at gmail dot com
  Target Milestone: ---
            Target: i?86-pc-solaris2.11, i686-pc-linux-gnu

Since 20220209, two tests FAIL on 32-bit Solaris/x86:

+FAIL: g++.target/i386/pr35513-1.C  -std=gnu++14 execution test
+FAIL: g++.target/i386/pr35513-1.C  -std=gnu++17 execution test
+FAIL: g++.target/i386/pr35513-1.C  -std=gnu++20 execution test
+FAIL: g++.target/i386/pr35513-1.C  -std=gnu++98 execution test
+FAIL: g++.target/i386/pr35513-2.C  -std=gnu++14 execution test
+FAIL: g++.target/i386/pr35513-2.C  -std=gnu++17 execution test
+FAIL: g++.target/i386/pr35513-2.C  -std=gnu++20 execution test
+FAIL: g++.target/i386/pr35513-2.C  -std=gnu++98 execution test

The tests SEGV like this:

    x86: Update PR 35513 tests

    1. Require linker with GNU_PROPERTY_1_NEEDED support for PR 35513
    run-time tests.
[...]
            PR testsuite/104481
            * g++.target/i386/pr35513-1.C: Require property_1_needed target.
            * g++.target/i386/pr35513-2.C: Likewise.
[...]
            * lib/target-supports.exp (check_compile): Support assembly code.
            (check_effective_target_property_1_needed): New proc.

I honestly don't see how check_effective_target_property_1_needed does test for
linker GNU_PROPERTY_1_NEEDED support, which Solaris ld certainly lacks, thus
the tests shouldn't run in the first place.
