Regtype
Regtype is a term used in computer science to describe a descriptor attached to a register in low-level code representations. It denotes the kind of data a register is intended to hold and informs the generation and validation of instructions. In practice, regtype helps compilers and runtimes perform type-safe code generation, optimize register usage, and prevent invalid operations.
In many register-based intermediate representations, each temporary or virtual register carries a regtype such as integer,
Usage of regtype varies by system and is not universally standardized. Some architectures or compiler pipelines
