This is defined in 1939 * INSTR0 (color) and INSTR2 (alpha). You can also select the special constants 1940 * zero and one. 1941 * Swizzling and negation happens in this stage, as well. 1942 * 1943 * Important: Color and alpha seem to be mostly separate, i.e. their sources 1944 * selection appears to be fully independent (the register storage is probably 1945 * physically split into a color and an alpha section). 1946 * However (because of the apparent physical split), there is some interaction 1947 * WRT swizzling. If, for example, you want to load an R component into an 1948 * Alpha operand, this R component is taken from a *color* source, not from 1949 * an alpha source. The corresponding register doesn't even have to appear in 1950 * the alpha sources list. (I hope this all makes sense to you) 1951 * 1952 * Destination selection 1953 * The destination register index is in FPI1 (color) and FPI3 (alpha) 1954 * together with enable bits. 1955 * There are separate enable bits for writing into temporary registers 1956 * (DSTC_REG_* /DSTA_REG) and program output registers (DSTC_OUTPUT_* 1957 * /DSTA_OUTPUT). You can write to both at once, or not write at all (the 1958 * same index must be used for both). 1959 * 1960 * Note: There is a special form for LRP 1961 * - Argument order is the same as in ARB_fragment_program. 1962 * - Operation is MAD 1963 * - ARG1 is set to ARGC_SRC1C_LRP/ARGC_SRC1A_LRP 1964 * - Set FPI0/FPI2_SPECIAL_LRP 1965 * Arbitrary LRP (including support for swizzling) requires vanilla MAD+MAD 1966 */ 1967 #define R300_US_ALU_RGB_ADDR_0 0x46C0 1968 #
