Regmap

Regmap


A regmap is a mapping from virtual register to virtual or physical register, and is used by MLRISC register allocators to represent the current binding of virtual registers. Regmaps are implemented as Intmap in MLRISC, and are defined in the CELLS interface.

Regmaps are used in phases such as assembly generation and machine code. MLRISC program representations such clusters and IR each contains a global regmap per compilation unit. Representations such as hyperblock may contain its own regmap, which overrides the global regmap.
