From 45fb78c9c456ace1d914c836d15af38ae345b902 Mon Sep 17 00:00:00 2001 From: Michael Meissner Date: Thu, 7 Apr 2022 18:25:17 -0400 Subject: [PATCH] Disable float128 tests on VxWorks, PR target/104253. 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). 2022-04-07 Michael Meissner gcc/testsuite/ PR target/104253 * lib/target-supports.exp (check_ppc_float128_sw_available): Do not run float128 tests on VxWorks.
