Subject: re-enable SSE code, except for the _mesa_sse_transform_points4_identity() function... 
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=bd09d49eb4c6b7e14b7ba68d83fd556976724fa5;p=mesa.git

re-enable SSE code, except for the _mesa_sse_transform_points4_identity() function.  Use the x86 version instead
