  1057.  *  - ADD, MUL, MAD etc.: use MAD with appropriate neutral operands
  1058.  *  - DP4: Use OUTC_DP4, OUTA_DP4
  1059.  *  - DP3: Use OUTC_DP3, OUTA_DP4, appropriate alpha operands
  1060.  *  - DPH: Use OUTC_DP4, OUTA_DP4, appropriate alpha operands
  1061.  *  - CMPH: If ARG2 > 0.5, return ARG0, else return ARG1
  1062.  *  - CMP: If ARG2 < 0, return ARG1, else return ARG0
  1063.  *  - FLR: use FRC+MAD
  1064.  *  - XPD: use MAD+MAD
  1065.  *  - SGE, SLT: use MAD+CMP
  1066.  *  - RSQ: use ABS modifier for argument
  1067.  *  - Use OUTC_REPL_ALPHA to write results of an alpha-only operation
  1068.  *    (e.g. RCP) into color register
  1069.  *  - apparently, there's no quick DST operation
  1070.  *  - fglrx set FPI2_UNKNOWN_31 on a "MAD fragment.color, tmp0, tmp1, tmp2"
  1071.  *  - fglrx set FPI2_UNKNOWN_31 on a "MAX r2, r1, c0"
  1072.  *  - fglrx once set FPI0_UNKNOWN_31 on a "FRC r1, r1"
  1073.  *
  1074.  * Operand selection
  1075.  * First stage selects three sources from the available registers and
  1076.  * constant parameters. This is defined in INSTR1 (color) and INSTR3 (alpha).
  1077.  * fglrx sorts the three source fields: Registers before constants,
  1078.  * lower indices before higher indices; I do not know whether this is
  1079.  * necessary.
  1080.  *
  1081.  * fglrx fills unused sources with "read constant 0"
  1082.  * According to specs, you cannot select more than two different constants.
  1083.  *
  1084.  * Second stage selects the operands from the sources. This is defined in
  1085.  * INSTR0 (color) and INSTR2 (alpha). You can also select the special constants
  1086.  * zero and one.
  1087.  * Swizzling and negation happens in this stage, as well.
  1088.  *
  1089.  * Important: Color and alpha seem to be mostly separate, i.e. their sources
  1090.  * selection appears to be fully independent (the register storage is probably
  1091.  * physically split into a color and an alpha section).
  1092.  * However (because of the apparent physical split), there is some interaction
  1093.  * WRT swizzling. If, for example, you want to load an R component into an
  1094.  * Alpha operand, this R component is taken from a *color* source, not from
  1095.  * an alpha source. The corresponding register doesn't even have to appear in
  1096.  * the alpha sources list. (I hope this all makes sense to you)
  1097.  *
  1098.  * Destination selection
  1099.  * The destination register index is in FPI1 (color) and FPI3 (alpha)
  1100.  * together with enable bits.
  1101.  * There are separate enable bits for writing into temporary registers
  1102.  * (DSTC_REG_* /DSTA_REG) and and program output registers (DSTC_OUTPUT_*
  1103.  * /DSTA_OUTPUT). You can write to both at once, or not write at all (the
  1104.  * same index must be used for both).
  1105.  *
  1106.  * Note: There is a special form for LRP
  1107.  *  - Argument order is the same as in ARB_fragment_program.
  1108.  *  - Operation is MAD
  1109.  *  - ARG1 is set to ARGC_SRC1C_LRP/ARGC_SRC1A_LRP
  1110.  *  - Set FPI0/FPI2_SPECIAL_LRP
  1111.  * Arbitrary LRP (including support for swizzling) requires vanilla MAD+MAD
