cmmExprAlignment :: CmmExpr -> Alignment Source #
Returns an alignment in bytes of a CmmExpr when it's a statically known integer constant, otherwise returns an alignment of 1 byte. The caller is responsible for using with a sensible CmmExpr argument.

localRegType :: LocalReg -> CmmType 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.
