pub static WIDENINGS: &[Fold]Expand description
The widenings a load can move into on this machine, which is tamnd/rucc#1894.
Every sign and zero widening the target has, each with the load of the width it reads and the instruction that reads that width out of memory and widens it. None of them has a second source to swap with. The zero widening from thirty two bits comes out as the load itself, since a thirty two bit load already clears the upper half of the register it writes.
