[Bf-committers] [Bf-blender-cvs] SVN commit: /data/svn/bf-blender [54299] trunk/blender/intern/cycles: Fix cycles intersection issue with overlapping faces on windows 32 bit and CPU

[Brecht Van Lommel]

Hi,

It should not be dropped, I renamed them explicitly to SSE now since
the intention is to eventually add explicit SSE calls to that kernel.
If we do that then the "non optimized" kernel should still work on
e.g. ARM, PPC, ...
