Detailed Description
The structure represents an allocno move. Both allocnos have the same original regno but different allocation.
Field Documentation
| move_t* move::deps |
Moves on which given move depends on. Dependency can be cyclic. It means we need a temporary to generates the moves. Sequence A1->A2, B1->B2 where A1 and B2 are assigned to reg R1 and A2 and B1 are assigned to reg R2 is an example of the cyclic dependencies.
