Description

Register classes for architectures which don't have any vector registers.

Synopsis

Documentation

data RegClass where Source #

The class of a register. Used in the register allocator. We treat all registers in a class as being interchangeable.

Bundled Patterns

getUnique :: RegClass -> Unique Source #

Outputable RegClass Source #

This instance is just used for the graph colouring register allocator. Prefer using either pprRegClass or pprRegClass, which is more informative.
