+ * Relative Addressing
+ * According to the value returned for MAX_PROGRAM_NATIVE_ADDRESS_REGISTERS_ARB
+ * there are only two address registers available. The destination in the ARL
+ * instruction is set to TEMP <n> (The temp isn't actually written).
+ *
+ * When using vanilla ARB_v_p, the proprietary driver will squish both the available
+ * ADDRESS regs into the first hardware reg in the X and Y components.
+ *
+ * To use an address reg as an index into consts, the CONST_SRC is set to
+ * (const_base + offset) and INDEX_CONST is set.
+ *
+ * It is similar for inputs, INPUT_SRC is set to the offset value and INDEX_INPUT
+ * is set.
+ *
+ * To access the second address reg use ADDR_REG_SELECT_1. A particular component
+ * of the address regs is selected with ADDR_SWZ.
+ *
+ * Only one address register can be accessed per instruction, but you may use
+ * the address reg as an index into both consts and inputs in the same instruction
+ * as long as the swizzles also match.
+ *
+ * Conditional execution (see NV_vertex_program{2,3} for details)
+ * All instructions appear to be able to modify one of two condition code registers.
+ * This is enabled by setting COND_UPDATE_ENABLE. The second condition registers is
+ * updated by setting COND_REG_SELECT_1.
+ *
+ * Conditional execution of an instruction is enabled by setting COND_TEST_ENABLE, and
+ * selecting the condition which will allow the test to pass with COND_{FL,LT,...}.
+ * It is possible to swizzle the values in the condition register, which allows for
+ * testing against an individual component.
+ *
+ * Branching
+ * The BRA/CAL instructions seem to follow a slightly different opcode layout. The
+ * destination instruction ID (IADDR) overlaps SRC2. Instruction ID's seem to be
+ * numbered based on the UPLOAD_FROM_ID FIFO command, and is incremented automatically
+ * on each UPLOAD_INST FIFO command.
+ *
+ * Conditional branching is achieved by using the condition tests described above.
+ * There doesn't appear to be dedicated looping instructions, but this can be done
+ * using a temp reg + conditional branching.
+ *
+ * Subroutines may be uploaded before the main program itself, but the first executed
+ * instruction is determined by the PROGRAM_START_ID FIFO command.

+ * Texture lookup
