Bootstrapped and regtested on s390x-redhat-linux. Ok for master?
Commit 5d9ade39b872 ("IBM Z: Fix PR97326: Enable fp compares in
vec_cmp") made it possible to create rtxes that describe signaling
comparisons on z13, which are not supported by the hardware. Restrict
this by using vcond_comparison_operator predicate.
gcc/ChangeLog:
2020-11-24 Ilya Leoshkevich <i...@linux.ibm.com>
* config/s390/vector.md: Use vcond_comparison_operator
predicate.
