How can altivec not be supported when you use -mcpu=power8?
For the test in question: builtins-1-be-folded.c:
The VxWorks header file altivec.h is included by builtins-1.fold.h
and the error is:
altivec.h:34:2: error: #error Use the "-maltivec" flag to enable PowerPC
AltiVec support
On VxWorks the kernel has to be configured for altivec regardless of the
-mcpu switch, and for unrelated reasons we cannot configure in altivec
at this time for our nightly testing.
