1577    My guess is the 10-bit formats are the 8-bit ones but with filtering being
1578    performed with the precision of 10 bits per channel. This makes sense
1579    with sRGB textures since the conversion to linear space reduces the precision
1580    significantly so the shader gets approximately the 8-bit precision
1581    in the end. It might also improve the quality of HDR rendering where
1582    high-precision filtering is desirable.
1583 
1584    Again, this is guessed, the formats might mean something entirely else.
1585    The others should be fine. */

1888 /* ALU
1889  * The ALU instructions register blocks are enumerated according to the order
1890  * in which fglrx. I assume there is space for 64 instructions, since
1891  * each block has space for a maximum of 64 DWORDs, and this matches reported
1892  * native limits.
1893  *
1894  * The basic functional block seems to be one MAD for each color and alpha,
1895  * and an adder that adds all components after the MUL.
1896  *  - ADD, MUL, MAD etc.: use MAD with appropriate neutral operands
1897  *  - DP4: Use OUTC_DP4, OUTA_DP4
1898  *  - DP3: Use OUTC_DP3, OUTA_DP4, appropriate alpha operands
1899  *  - DPH: Use OUTC_DP4, OUTA_DP4, appropriate alpha operands
1900  *  - CMPH: If ARG2 > 0.5, return ARG0, else return ARG1
1901  *  - CMP: If ARG2 < 0, return ARG1, else return ARG0
1902  *  - FLR: use FRC+MAD
1903  *  - XPD: use MAD+MAD
1904  *  - SGE, SLT: use MAD+CMP
1905  *  - RSQ: use ABS modifier for argument
1906  *  - Use OUTC_REPL_ALPHA to write results of an alpha-only operation
1907  *    (e.g. RCP) into color register
1908  *  - apparently, there's no quick DST operation
1909  *  - fglrx set FPI2_UNKNOWN_31 on a "MAD fragment.color, tmp0, tmp1, tmp2"
1910  *  - fglrx set FPI2_UNKNOWN_31 on a "MAX r2, r1, c0"
1911  *  - fglrx once set FPI0_UNKNOWN_31 on a "FRC r1, r1"
1912  *
1913  * Operand selection
1914  * First stage selects three sources from the available registers and
1915  * constant parameters. This is defined in INSTR1 (color) and INSTR3 (alpha).
1916  * fglrx sorts the three source fields: Registers before constants,
1917  * lower indices before higher indices; I do not know whether this is
1918  * necessary.
1919  *
1920  * fglrx fills unused sources with "read constant 0"
1921  * According to specs, you cannot select more than two different constants.
1922  *
1923  * Second stage selects the operands from the sources. This is defined in
1924  * INSTR0 (color) and INSTR2 (alpha). You can also select the special constants
1925  * zero and one.
1926  * Swizzling and negation happens in this stage, as well.
1927  *
1928  * Important: Color and alpha seem to be mostly separate, i.e. their sources
1929  * selection appears to be fully independent (the register storage is probably
1930  * physically split into a color and an alpha section).
1931  * However (because of the apparent physical split), there is some interaction
1932  * WRT swizzling. If, for example, you want to load an R component into an
1933  * Alpha operand, this R component is taken from a *color* source, not from
1934  * an alpha source. The corresponding register doesn't even have to appear in
1935  * the alpha sources list. (I hope this all makes sense to you)
1936  *
1937  * Destination selection
1938  * The destination register index is in FPI1 (color) and FPI3 (alpha)
1939  * together with enable bits.
1940  * There are separate enable bits for writing into temporary registers
1941  * (DSTC_REG_* /DSTA_REG) and program output registers (DSTC_OUTPUT_*
1942  * /DSTA_OUTPUT). You can write to both at once, or not write at all (the
1943  * same index must be used for both).
1944  *
1945  * Note: There is a special form for LRP
1946  *  - Argument order is the same as in ARB_fragment_program.
1947  *  - Operation is MAD
1948  *  - ARG1 is set to ARGC_SRC1C_LRP/ARGC_SRC1A_LRP
1949  *  - Set FPI0/FPI2_SPECIAL_LRP
1950  * Arbitrary LRP (including support for swizzling) requires vanilla MAD+MAD
