...lue in IPA instruction generation. https://cgit.freedesktop.org/mesa/mesa/tree/src/gallium/drivers/nouveau/codegen/nv50_ir_emit_gm107.cpp#L2561 Register on 0x14 (20) is set to some source on "insn->op == OP_PINTERP" I have found while emulation that such value can be set sometimes to FragCoord.w, I don't however know what that value is and how to represent it on glsl. Do you guys know where does that value come from and what it means? -- Atentamente, *Fernando A.
