Global registers

data GlobalReg Source #

An abstract global register for the STG machine.

See also GlobalRegUse, which denotes a usage of a register at a particular type (e.g. using a 32-bit wide register to store an 8-bit wide value), as per Note [GlobalReg vs GlobalRegUse].

data GlobalRegUse Source #

A use of a global register at a particular type.

While a GlobalReg identifies a global register in the STG machine, a GlobalRegUse also contains information about the type we are storing in the register.

See Note [GlobalReg vs GlobalRegUse] for more information.
