From c917584aa9ec32934acf0082ed383b04f49fd174 Mon Sep 17 00:00:00 2001 From: Douglas Rupp Date: Mon, 18 May 2020 11:43:48 -0700 Subject: [PATCH] Require powerpc_vsx_ok in gcc.target/powerpc/pr71763.c We're getting an error when running this test on PowerPC VxWorks 7, due to an unexpected warning: | Excess errors: | cc1: warning: '-mvsx' and '-mno-altivec' are incompatible The warning comes from a combination of factors: - The test itself uses -mvsx explicitly via the following directive: // { dg-options "-O1 -mvsx" } - Our toolchain was configured so as to make -mno-altivec the default; - These two options are mutually exclusive. This commit adds a powerpc_vsx_ok dg-require-effective-target directive to that test, and thus making it UNSUPPORTED instead. Tested on PowerPC VxWorks 7. Also tested on PowerPC ELF as well, a platform where we do not make -mno-altivec the default, to verify that the test continues to run as usual in that case. gcc/testsuite/ * gcc.target/powerpc/pr71763.c: Require powerpc_vsx_ok. --- gcc/testsuite/ChangeLog | 4 ++++ gcc/testsuite/gcc.target/powerpc/pr71763.c | 1 + 2 files changed, 5 insertions(+) diff --git a/gcc/testsuite/ChangeLog b/gcc/testsuite/ChangeLog index 858eb60..ad5b28d 100644 --- a/gcc/testsuite/ChangeLog +++ b/gcc/testsuite/ChangeLog @@ -1,3 +1,7 @@ +2020-05-18 Doug Rupp + + * gcc.target/powerpc/pr71763.c: Require powerpc_vsx_ok. + 2020-05-18 Harald Anlauf PR fortran/95053 diff --git a/gcc/testsuite/gcc.target/powerpc/pr71763.c b/gcc/testsuite/gcc.target/powerpc/pr71763.c index b36ddfa..b888839 100644 --- a/gcc/testsuite/gcc.target/powerpc/pr71763.c +++ b/gcc/testsuite/gcc.target/powerpc/pr71763.c @@ -1,5 +1,6 @@ // PR target/71763 // { dg-do compile } +// { dg-require-effective-target powerpc_vsx_ok } // { dg-options "-O1 -mvsx" } int a, b; -- 2.7.4
