Hello,
(submitting this on behalf of Doug Rupp, one of my colleagues)
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.
OK for master?
Thanks!
