1066	* - Use OUTC_REPL_ALPHA to write results of an alpha-only operation
1067	* (e.g. RCP) into color register
1068	* - apparently, there's no quick DST operation
1069	* - fglrx set FPI2_UNKNOWN_31 on a "MAD fragment.color, tmp0, tmp1, tmp2"
1070	* - fglrx set FPI2_UNKNOWN_31 on a "MAX r2, r1, c0"
1071	* - fglrx once set FPI0_UNKNOWN_31 on a "FRC r1, r1"
1072	*
1073	* Operand selection
1074	* First stage selects three sources from the available registers and
1075	* constant parameters. This is defined in INSTR1 (color) and INSTR3 (alpha).
1076	* fglrx sorts the three source fields: Registers before constants,
1077	* lower indices before higher indices; I do not know whether this is
1078	* necessary.
1079	*
1080	* fglrx fills unused sources with "read constant 0"
1081	* According to specs, you cannot select more than two different constants.
1082	*
1083	* Second stage selects the operands from the sources. This is defined in
1084	* INSTR0 (color) and INSTR2 (alpha). You can also select the special constants
1085	* zero and one.
1086	* Swizzling and negation happens in this stage, as well.
1087	*
1088	* Important: Color and alpha seem to be mostly separate, i.e. their sources
1089	* selection appears to be fully independent (the register storage is probably
1090	* physically split into a color and an alpha section).
1091	* However (because of the apparent physical split), there is some interaction
1092	* WRT swizzling. If, for example, you want to load an R component into an
1093	* Alpha operand, this R component is taken from a color source, not from
1094	* an alpha source. The corresponding register doesn't even have to appear in
1095	* the alpha sources list. (I hope this all makes sense to you)
1096	*
1097	* Destination selection
1098	* The destination register index is in FPI1 (color) and FPI3 (alpha)
1099	* together with enable bits.
1100	* There are separate enable bits for writing into temporary registers
1101	* (DSTC_REG_* /DSTA_REG) and and program output registers (DSTC_OUTPUT_*
1102	* /DSTA_OUTPUT). You can write to both at once, or not write at all (the
1103	* same index must be used for both).
1104	*
1105	* Note: There is a special form for LRP
1106	* - Argument order is the same as in ARB_fragment_program.
1107	* - Operation is MAD
1108	* - ARG1 is set to ARGC_SRC1C_LRP/ARGC_SRC1A_LRP
1109	* - Set FPI0/FPI2_SPECIAL_LRP
1110	* Arbitrary LRP (including support for swizzling) requires vanilla MAD+MAD
