<p><font size=3 face="Times New Roman"><span style='font-size:12.0pt'>I'm
taking a stab at implmenting D3DXAssembleShader, which takes shader
instructions like "mul r1, r2.xy, r3.z" and turns them into binary
code (one-to-one mapping). Although I've got very little clue what I'm really
doing, I've come quite a way on a parser that breaks it down into the
separate parts and made some reverse lookups on tables of opcodes, registrys,
masks etc. that I found in the wine code. I've basicly come so far that I got
the parts like mul = 0x00000005, r = temp registry = 0x00000000, register
number = 0x00000001, writemask = 0x000F0000 etc. for all the arguments, but
I'm struggling a bit putting it all together into the correct binary format.
I have found a lot of material on the *text* format of the shader
instructions, but pretty much none on the binary format. Clearly some
documentation must have been used/made when you implemented glsl and the
other shader backends as they read this stuff and translates it to OpenGL
calls. Does anyone have anything they could share with me? <o:p></o:p></span></font></p>
<p><font size=3 face="Times New Roman"><span style='font-size:12.0pt'>P.S.
Don't expect too much of me though, 1) It's so ugly it makes grown men cry,
2) Current it leaks memory bigtime and 3) It's a text hack that will never
validate shader code or anything like that BUT I think I can make this work
for code that already works.<o:p></o:p></span></font></p>
<p><font size=3 face="Times New Roman"><span style='font-size:12.0pt'>On a different
note, a game I have is pulling up two completely unknown texture formats R16
and AL16 as fourcc. I figured I could at least find out something about them
and add them to the debug tables, but the only references I find on google
are to wine and wine bug reports. I figure they may be related to R16F (same
with ints?) and L16 (luminosity, so AL16 with alpha?) but I can't find
anything on them.<o:p></o:p></span></font></p>
<p><font size=3 face="Times New Roman"><span style='font-size:12.0pt'>Oh yeah
and for the misc question - where's the right place to add test code? I
expect my D3DXAssembleShader function will need a lot of it - at least
one for each opcode, registry tests, write mask tests, whitespace and
commenting tests+++. No code for you to review yet, not until it works. THEN
you can bring out the tar and feathers over the code. <o:p></o:p></span></font></p>
