commit 4c69ebe01784595a080b66e81042c92f88a2be6b
Author: Christophe Lyon <christophe.lyon@linaro.org>
Date: Wed Feb 24 19:58:58 2021 +0000
arm: Factorize all MVE vcmp*
After removing the signed and unsigned suffixes in the previous
patches, we can now factorize the vcmp* patterns: there is no longer
an asymmetry where operators do not have the same set of signed and
unsigned variants.
The will make maintenance easier.
MVE has a different set of vector comparison operators than Neon,
so we have to introduce dedicated iterators.

* config/arm/iterators.md (MVE_COMPARISONS): New.
(mve_cmp_op): New.
(mve_cmp_type): New.
* config/arm/mve.md (mve_vcmp<mve_cmp_op>q_<mode>): New, merge all
mve_vcmp patterns.
(mve_vcmpneq_<mode>, mve_vcmpcsq_n_<mode>, mve_vcmpcsq_<mode>)
