This method should be implemented to expand the instruction at *MBBI.

The iteration over the current basic block will continue at NextMBBI. This method should return true if it replaced the instruction at *MBBI.

◆ run()

bool RISCVExpandPseudoImplBase::run ( MachineFunction & MF )

Expand a subset of pseudos in the current function.

Returns whether the function was modified.

This will assert if expansion increased the estimated size of the function.
