This is defined in * INSTR0 (color) and INSTR2 (alpha). You can also select the special constants * zero and one. * Swizzling and negation happens in this stage, as well. * * Important: Color and alpha seem to be mostly separate, i.e. their sources * selection appears to be fully independent (the register storage is probably * physically split into a color and an alpha section). * However (because of the apparent physical split), there is some interaction * WRT swizzling. If, for example, you want to load an R component into an * Alpha operand, this R component is taken from a *color* source, not from * an alpha source.

You can write to both at once, or not write at all (the * same index must be used for both). * * Note: There is a special form for LRP * - Argument order is the same as in ARB_fragment_program. * - Operation is MAD * - ARG1 is set to ARGC_SRC1C_LRP/ARGC_SRC1A_LRP * - Set FPI0/FPI2_SPECIAL_LRP * Arbitrary LRP (including support for swizzling) requires vanilla MAD+MAD */ #define R300_PFS_INSTR1_0
