DXBC Reader

A dxbc reader with rust implementation. It is not well done now and need more time to finish it.

Build

• Rust 1.58.0-nightly

Run

dxbc_reader [IN={Pos tex0 tex1 color}] [OUT={SV_Position tex color}] input.dxbc

Todo

• Semantic Analysis for the labels for different usage(variable).
• ConstantBuffer defines

Examples

mul r0.xyzw, v0.yyyy, cb1[1].xyzw
mad r0.xyzw, cb1[0].xyzw, v0.xxxx, r0.xyzw
mad r0.xyzw, cb1[2].xyzw, v0.zzzz, r0.xyzw
mad r0.xyzw, cb1[3].xyzw, v0.wwww, r0.xyzw
mad r0.xyzw, v2.xxxx, cb0[4].xyzw, r0.xyzw
mad r0.xyzw, v2.yyyy, cb0[5].xyzw, r0.xyzw
mul r1.xyz, r0.yyyy, cb2[18].xywx
mad r1.xyz, cb2[17].xywx, r0.xxxx, r1.xyzx
mad r0.xyz, cb2[19].xywx, r0.zzzz, r1.xyzx
mad o0.xyw, cb2[20].xyxw, r0.wwww, r0.xyxz
mov o0.z, l(0)
mov o1.xy, v1.xyxx
add r0.x, -v3.w, cb0[2].y
add r0.y, -cb0[2].w, l(1.000000)
mad r0.x, |r0.x|, r0.y, cb0[2].w
mul_sat r0.xyzw, r0.xxxx, v3.xyzw
mul o2.xyzw, r0.xyzw, cb0[2].zzzz
