-Thoughts on vertex program optimization:

-The obvious thing to do is to compile the vertex program into X86/SSE/3DNow!
-assembly code. That will probably be a lot of work.
-
-Another approach might be to replace the vp_instruction->Opcode field with
-a pointer to a specialized C function which executes the instruction.
-In particular we can write functions which skip swizzling, negating,
-masking, relative addressing, etc. when they're not needed.

-
-void simple_add( struct prog_instruction *inst )

-A first step would be to 'vectorize' the programs in the same way as
-the normal transformation code in the tnl module. Thus each opcode
-takes zero or more input vectors (registers) and produces one or more
-output vectors.
-
-These operations would intially be coded in C, with machine-specific
-assembly following, as is currently the case for matrix
-transformations in the math/ directory. The preprocessing scheme for
-selecting simpler operations Brian describes above would also work
-here.
-
-This should give reasonable performance without excessive effort.
