| IF?
| IF
| If condition (don't know how condition flags work yet) is true, then executes instructions until DST, then jumps to DST+NUM; else, jumps to DST
| If condition (don't know how condition flags work yet, based on cmp.x and cmp.y booleans set by CMP) is true, then executes instructions until DST, then jumps to DST+NUM; else, jumps to DST

| CMP1
| CMP
| Presumably compares two vectors component by component and sets the appropriate flags. (unknown exactly how this works as of yet)
| Sets booleans cmp.x and cmp.y based on the operand's x and y components and the CMPX and CMPY comparison operators respectively.
