Subject: S/390: Remove code duplication in vec_unordered<mode>
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=021f65807164b2770e8f113b0f85b1bb193020ef;p=gcc.git

S/390: Remove code duplication in vec_unordered<mode>

vec_unordered<mode> is vec_ordered<mode> plus a negation at the end.
Reuse vec_unordered<mode> logic.

gcc/ChangeLog:

2019-09-30  Ilya Leoshkevich  <iii@linux.ibm.com>

	PR target/77918
	* config/s390/vector.md (vec_unordered<mode>): Call
	gen_vec_ordered<mode>.
