/* Restrictions of ALU instructions
|

|
|
* max of 3 different src GPRs per instr.
|
|
* max of 4 different cfile constant components per instr.
|
|
* max of 2 (different) constants (any type) for t.
|
|
* bank swizzle (see below).
|
|
* GPR write stalls read of same register. Auto-replaced by PV/PS, NOP needed if registers are relative to
|
|
* different indices (gpr,loop,nothing).
|
|
* may use constant registers or constant cache, but not both.
|

*/
|
|
|
|
/* Bank_swizzle: (pp. 297ff)
|
|
* Only one of each x,y,z,w GPR component can be loaded per cycle (3 cycles per instr, called 0-2).
|
|
* per scalar instruction bank_swizzle can select which cycle each operand comes from. e.g.:
|
|
* SRC0 SRC1 SRC2 SWIZZLE cycle0 cycle1 cycle2
|
|
* 1.x 2.x 012 1.x 2.x -
|
|
* 3.x 1.y 201 1.y - 3.x
|
|
* 2.x 1.y 102 (1.y) (2.x) -
|
|
* If data is read in a cycle, multiple scalar instructions can reference it.
|
|
* Special case: square() - i.e. same component in src0+src1 doesn't need read port -> ignores swizzle for src1.
|
|
* No restrictions for constants or PV/PS.
|
|
* t can load multiple components in a single cycle slot, but has to share cycles with xyzw.
|
|
* t with single constant may not load GPRs or PV/PS in cycle 0 (carefull with ALU_TRANS_210).
|
|
* t with two constants may only load GPRs or PV/PS in cycle 2.
