Bug ID: 79395
Summary: Compile error with -mcpu=power9 and
__builtin_vec_vcmpne_p
Product: gcc
Version: 7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3

Target Milestone: ---
Target: powerpc64*-*-*
Testing with trunk and -mcpu=power9 we get the error below from a number of
tests in gcc.dg/vmx:

This change makes the error go away but it may be removing other things that do
work properly:
