GHC.Platform.Reg.Class.Unified

Description

Register classes for architectures which don't have separate registers for scalar floating-point values separate from vector registers.

Synopsis

- data RegClass where
  - pattern RcInteger :: RegClass
  - pattern RcFloatOrVector :: RegClass
- pprRegClass :: RegClass -> SDoc
- allRegClasses :: [RegClass]

# Documentation

data RegClass where #

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

Bundled Patterns

pattern RcInteger :: RegClass |
pattern RcFloatOrVector :: RegClass |
