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 *
167 * NV40 Looping
168 *   Loops appear to be fairly expensive on NV40 at least, the proprietary
169 *   driver goes to a lot of effort to avoid using the native looping
170 *   instructions.  If the total number of *executed* instructions between
171 *   REP/ENDREP or LOOP/ENDLOOP is <=500, the driver will unroll the loop.
172 *   The maximum loop count is 255.
