# Documentation

data MachOp #

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.

Methods showsPrec :: Int -> MachOp -> ShowS Source # show :: MachOp -> String Source # showList :: [MachOp] -> ShowS Source #

pprMachOp :: MachOp -> SDoc #

isCommutableMachOp :: MachOp -> Bool #

Returns `True` if the MachOp has commutable arguments. This is used in the platform-independent Cmm optimisations.

If in doubt, return `False`. This generates worse code on the native routes, but is otherwise harmless.

isAssociativeMachOp :: MachOp -> Bool #

Returns `True` if the MachOp is associative (i.e. `(x+y)+z == x+(y+z)`) This is used in the platform-independent Cmm optimisations.

If in doubt, return `False`. This generates worse code on the native routes, but is otherwise harmless.

isComparisonMachOp :: MachOp -> Bool #

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 #

Returns `Just w` if the operation is an integer comparison with width `w`, or `Nothing` otherwise.

machOpResultType :: DynFlags -> MachOp -> [CmmType] -> CmmType #

Returns the MachRep of the result of a MachOp.

machOpArgReps :: DynFlags -> MachOp -> [Width] #

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.
