So after installing SSE functions the same 3dnow normalize was tested again. Thanks for testing on an SSE machine.

And: _transform_normalize_normals_no_rot _transform_rescale_normals_no_rot _transform_rescale_normals _transform_normals_no_rot _transform_normals _normalize_normals _rescale_normals These should be tested too, while we're at it. Agreed. Brian: If such tests do get written, where should they live in the tree? There's a number of test routines in the src/math/m_debug_*.c files. I think that would be the place to add more if needed. It's all there. Even benchmarking is included. It just needs to be recompiled with DEBUG and RUN_DEBUG_BENCHMARK defined.

Now it reports no more problems :) in any of the math functions tested on my Duron. This should be about everything except SSE. I've checked in the patch to the Mesa and DRI trees.

I couldn't care less whether there is or isn't a GUI / TUI configuration program. What I do care about is that the configuration files must be stored in a file which can be edited, run through a script, etc. All the configuration files on my box which I've ever had to edit / bothered to look, have never been in XML, and I don't see a good enough reason to start now. > KISS principle.

Well I'd consider XML to not be simpler than XF86Config-4, besides which it is uneccessary, what happened to the "don't implement it if you don't need it" philosophy? cheers Liam --- This SF.NET email is sponsored by: SourceForge Enterprise Edition + IBM + LinuxWorld = Something 2 See! http://www.vasoftware.com ___ Dri-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/dri-devel
