 132  * There appears to be no special difference between result regs and temp regs.
 133  *     result.color == R0.xyzw
 134  *     result.depth == R1.z
 135  * When the fragprog contains instructions to write depth, NV30_TCL_PRIMITIVE_3D_UNK1D78=0
 136  * otherwise it is set to 1.
 137  *
 138  * Constants are inserted directly after the instruction that uses them.
 139  *
 140  * It appears that it's not possible to use two input registers in one
 141  * instruction as the input sourcing is done in the instruction dword
 142  * and not the source selection dwords.  As such instructions such as:
 143  *
 144  *     ADD result.color, fragment.color, fragment.texcoord[0];
 145  *
 146  * must be split into two MOV's and then an ADD (nvidia does this) but
 147  * I'm not sure why it's not just one MOV and then source the second input
 148  * in the ADD instruction..
 149  *
 150  * Negation of the full source is done with NV30_FP_REG_NEGATE, arbitrary
 151  * negation requires multiplication with a const.
 152  *
 153  * Arbitrary swizzling is supported with the exception of SWIZZLE_ZERO/SWIZZLE_ONE
 154  * The temp/result regs appear to be initialised to (0.0, 0.0, 0.0, 0.0) as SWIZZLE_ZERO
 155  * is implemented simply by not writing to the relevant components of the destination.
 156  *
 157  * Conditional execution
 158  *   TODO
 159  *
 160  * Non-native instructions:
 161  *   LIT
 162  *   LRP - MAD+MAD
 163  *   SUB - ADD, negate second source
 164  *   RSQ - LG2 + EX2
 165  *   POW - LG2 + MUL + EX2
 166  *   SCS - COS + SIN
 167  *   XPD
 168  *
 169  * NV40 Looping
 170  *   Loops appear to be fairly expensive on NV40 at least, the proprietary
 171  *   driver goes to a lot of effort to avoid using the native looping
 172  *   instructions.  If the total number of *executed* instructions between
 173  *   REP/ENDREP or LOOP/ENDLOOP is <=500, the driver will unroll the loop.
 174  *   The maximum loop count is 255.
