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.
For example:
void simple_add( struct vp_instruction *inst )
{
GLfloat *sum = machine->Registers[inst->DstReg.Register];
GLfloat *a = machine->Registers[inst->SrcReg[0].Register];
GLfloat *b = machine->Registers[inst->SrcReg[1].Register];
sum[0] = a[0] + b[0];
sum[1] = a[1] + b[1];
sum[2] = a[2] + b[2];
sum[3] = a[3] + b[3];
}

/*
KW:
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.
