Documentation
Machine-level primops; ones which we can reasonably delegate to the native code generators to handle.
Most operations are parameterised by the Width
that they operate on.
Some operations have separate signed and unsigned versions, and float
and integer versions.
isCommutableMachOp :: MachOp -> Bool Source #
isAssociativeMachOp :: MachOp -> Bool Source #
isComparisonMachOp :: MachOp -> Bool Source #
Returns True
if the MachOp is a comparison.
If in doubt, return False. This generates worse code on the native routes, but is otherwise harmless.
maybeIntComparison :: MachOp -> Maybe Width Source #
Returns Just w
if the operation is an integer comparison with width
w
, or Nothing
otherwise.
machOpResultType :: DynFlags -> MachOp -> [CmmType] -> CmmType Source #
Returns the MachRep of the result of a MachOp.
machOpArgReps :: DynFlags -> MachOp -> [Width] Source #
This function is used for debugging only: we can check whether an application of a MachOp is "type-correct" by checking that the MachReps of its arguments are the same as the MachOp expects. This is used when linting a CmmExpr.
