Duncan Brawley 0ea39c6305 pco: Use vertex input registers in register allocation ... Add support for the use of vertex input registers as additional general purpose registers which previously was restricted to temporary registers. Use of vertex input registers as additional general purpose registers is not available for fragment shaders. Vertex input registers are similar to temporary registers. The only difference is that vertex input registers can contain pre-initialised data when the shader starts. By default, the number of vertex input registers used for register allocation is the number of vertex input registers used for their pre-initialised data rounded up to the nearest multiple of 4, as vertex input registers are allocated in blocks of 4. If PCO_DEBUG=alloc_extra_vtxins is used, a mimimum of 12 vertex input registers are available for register allocation.
