Documentation
closureInfoStat :: Bool -> ClosureInfo -> JStgStat Source #
Generate statements to set infotable field values for the given ClosureInfo
Depending on debug flag, it generates h$setObjInfo(...) or h$o(...). The latter form doesn't store the pretty-printed name in the closure to save space.
Arguments
| :: ClosureInfo | object being info'd see |
| -> JSM JStgStat | rhs |
| -> JSM JStgStat |
Special case of closures that do not need to generate any fresh names
conClosure :: Ident -> FastString -> CILayout -> Int -> JSM JStgStat Source #
Used to pass arguments to newClosure with some safety
newClosure :: Closure -> JStgExpr Source #
Constructors

jsClosureCount :: Int Source #
We use this in the RTS to determine the number of generated closures. These closures use the names cached here, so we bind them to the same number.
