Subject: rs6000: lxsdux / stxsdux do not exist
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1bd1aa451d5020b81fb33fa9d64827e21a38eb23;p=thirdparty%2Fgcc.git

rs6000: lxsdux / stxsdux do not exist

Our md files refer to {l,st}xsd%U<n>x, but no {l,st}xsdux insns exist.
This patch removes the update forms.  All these use  constraint "Z"
which does not allow update form, so there is no practical difference.


	* config/rs6000/rs6000.md (*mov<mode>_hardfloat32): Remove %U from the
	lxsdx and stxsdx alternatives.
	(*mov<mode>_hardfloat64): Ditto.
	* config/rs6000/vsx.md (*vsx_extract_<mode>_store): Ditto.
