Subject: rs6000: Simplify <VSa> for VSX_TI
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=cd9346a157c48d3fc5a059ca763ecb74178abeb8;p=gcc.git

rs6000: Simplify <VSa> for VSX_TI

When used in VSX_TI, <VSa> is always just "wa".


	* config/rs6000/vsx.md: Replace all <VSa> that are used with VSX_TI
	with just "wa".
