Subject: [PATCH] arm: [MVE intrinsics] factorize vmaxaq vminaq
Factorize vmaxaq vminaq so that they use the same pattern.
2022-09-08 Christophe Lyon <christophe.lyon@arm.com>
gcc/
* config/arm/iterators.md (MVE_VMAXAVMINAQ, MVE_VMAXAVMINAQ_M):
New.
(mve_insn): Add vmaxa, vmina.
(supf): Add VMAXAQ_S, VMAXAQ_M_S, VMINAQ_S, VMINAQ_M_S.
* config/arm/mve.md (mve_vmaxaq_s<mode>, mve_vminaq_s<mode>):
Merge into ...
(@mve_<mve_insn>q_<supf><mode>): ... this.
(mve_vmaxaq_m_s<mode>, mve_vminaq_m_s<mode>): Merge into ...
(@mve_<mve_insn>q_m_<supf><mode>): ... this.
