Subject: [arm] Use neon_dot_q type for 128-bit V[US]DOT instructions where appropriate
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=51e6029f6994e9185f6ba931402bd7f64f891237;p=gcc.git

[arm] Use neon_dot_q type for 128-bit V[US]DOT instructions where appropriate

For the Dot Product instructions we have the scheduling types neon_dot and neon_dot_q for the 128-bit versions.
It seems that we're only using the former though, not assigning the neon_dot_q type anywhere.

This patch fixes that by adding the <q> mode attribute suffix to the type, similar to how we do it for other
types in neon.md.

	* config/arm/neon.md (neon_<sup>dot<vsi2qi>):
	Use neon_dot<q> for type.
	(neon_<sup>dot_lane<vsi2qi>): Likewise.
