From: Michael Meissner <meissner@gcc.gnu.org> To: gcc-cvs@gcc.gnu.org Subject: [gcc(refs/users/meissner/heads/work085)] Disable float128 tests on VxWorks. Date: Wed, 6 Apr 2022 22:52:35 +0000 (GMT) [thread overview] Message-ID: <20220406225235.16A8E3858D37@sourceware.org> (raw) https://gcc.gnu.org/g:c8dddce847649ec8ff180691c10be63605d88028 commit c8dddce847649ec8ff180691c10be63605d88028 Author: Michael Meissner <meissner@linux.ibm.com> Date: Wed Apr 6 18:52:16 2022 -0400 Disable float128 tests on VxWorks. In PR target/104253, it was pointed out the that test case added as part of fixing the PR does not work on VxWorks because float128 is not supported on that system. I have modified the three tests for float128 so that they are manually excluded on VxWorks systems. In looking at the code, I also added checks in check_effective_target_ppc_ieee128_ok to disable the systems that will never support VSX instructions which are required for float128 support (eabi, eabispe, darwin). 2022-04-06 Michael Meissner <meissner@linux.ibm.com> gcc/testsuite/ PR target/104253 * lib/target-supports.exp (check_ppc_float128_sw_available): Do not run float128 tests on VxWorks. (check_ppc_float128_hw_available): Likewise. (check_effective_target_ppc_ieee128_ok): Do not run float128 tests on VxWorks. Also disable systems that do not support VSX instructions.
