Subject: gallium: The SWZ opcode no longer aliases MOV.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=837d49a84e24420dbc06924f4862a5f7dcf4cace;p=mesa.git

gallium: The SWZ opcode no longer aliases MOV.

Also, when the extended swizzle token is used, the simple swizzle
and negate are set to X,Y,Z,W and FALSE, respectively.
