Documentation
tryCompileExpr :: Id -> CoreExpr -> CoreM (Either Error a) Source #
Try to compile an expression. Perhaps return an error.
intSubstitution :: CoreBind -> CoreM (Either Error CoreBind) Source #
For gsizeOf and galignment - calculate the variables.
offsetSubstitution :: CoreBind -> CoreM (Either Error CoreBind) Source #
Try to substitute the offsets.
offsetSubstitutionTree :: [OffsetScope] -> CoreExpr -> CoreM (Either Error CoreExpr) Source #
Substitute the offsets in a tree. All top-level local ids should be alread in place. Now try to compile selected expressions (See note [Offset substitution])
getScopeId :: OffsetScope -> Id Source #
Get Id from OffsetScope
getScopeExpr :: OffsetScope -> CoreExpr Source #
Get CoreExpr from OffsetScope
intListExpr :: [Int] -> CoreExpr Source #
Create a list expression from Haskell list.
exprToIntList :: Id -> CoreExpr -> CoreM (Either Error OffsetScope) Source #
Compile expression to list and then write it back to core expr.
isLitOrGlobal :: CoreExpr -> Maybe CoreExpr Source #
Return the expression if it's a literal or global.
inScopeAll :: [OffsetScope] -> CoreExpr -> Maybe CoreExpr Source #
Check whether the given CoreExpr is an id, and if yes - substitute it.
caseExprIndex :: [OffsetScope] -> CoreExpr -> Maybe CoreExpr Source #
Try to create a compileable version of case expr body. For !! @Int offsets val expressions.
compileGStorableBind :: CoreBind -> CoreM (Either Error CoreBind) Source #
Compile the expression in Core Bind and replace it.
