X-Git-Tag: basepoints/gcc-15~9510
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=5ea7a47c8586d3d62a2679413a74edab19dd87ea;p=thirdparty%2Fgcc.git

arm: [MVE intrinsics] factorize vmaxnmq vminnmq

Factorize vmaxnmq and vminnmq so that they use the same pattern.

2022-09-08  Christophe Lyon  <christophe.lyon@arm.com>

	gcc/
	* config/arm/iterators.md (MAX_MIN_F): New.
	(MVE_FP_M_BINARY): Add VMAXNMQ_M_F, VMINNMQ_M_F.
	(mve_insn): Add vmaxnm, vminnm.
	(max_min_f_str): New.
	* config/arm/mve.md (mve_vmaxnmq_f<mode>, mve_vminnmq_f<mode>):
	Merge into ...
	(@mve_<max_min_f_str>q_f<mode>): ... this.
	(mve_vmaxnmq_m_f<mode>, mve_vminnmq_m_f<mode>): Merge into ...
	(@mve_<mve_insn>q_m_f<mode>): ... this.
