RE: [fog-dev] CG Shader Parser
Mike Tajmajer
I actually have a small CG program running now as well!
// This is C2E2f_passthru from "The Cg Tutorial" (Addison-Wesley, ISBN
// 0321194969) by Randima Fernando and Mark J. Kilgard. See page 53.
struct C2E2f_Output {
float4 color : COLOR;
};
C2E2f_Output C2E2f_passthru(float4 color : COLOR)
{
C2E2f_Output OUT;
OUT.color = color;
return OUT;
}

I'd like to make the possibility to include foundation for shaders in
Fog this week, I hope the time will be sufficient,
Really sorry about my slow replies at this time

I am just wonder of Status.
There is no rush!

I'm still not ready with this:(
I'd like to release AsmJit-1.0 beta so we can use new AsmJit for such thing, but it's not finished yet. Is your shader experiment somewhere available so I can review the design?
Mike Tajmajer
Hi Petr,
Waiting for AsmJit 1.0 would be fine.
As I implement the opcodes and figure out the nuances of the grammar I am making changes to the code.
I will post the grammar and part of the code generation that is working.
I'll likely be rewriting it as I move forward -- so the design is still in flux!

I'd like to help you with implementation. Last week I did some optimizations in MathPresso (expression JIT compiler) and I think that JIT compilation has big potential, also read my latest post:
http://fog-framework.blogspot.com/2010/07/fog-graphics-and-jit-compilation.html
Fog is moving to the first ideas and I think that this is great!
I found also very interesting article about optimizations here:
http://www.redhat.com/magazine/002dec04/features/gcc/
But I think that we need to start with simple implementation making it robust later.
I think that I will release AsmJit-1.0 beta next week so we can start with experiments!
