val lambda_to_flambda : backend:(module Backend_intf.S) -> module_ident:Ident.t -> size:int -> filename:string -> Lambda.lambda -> Flambda.program
Flambda intermediate language code from
Lambda code by performing a form of closure conversion.
Function declarations (which may bind one or more variables identifying functions, possibly with mutual recursion) are transformed to
Project_closure expressions are then used to select a closure for a particular function from a
Set_of_closures expression. The
Set_of_closures expressions say nothing about the actual runtime layout of the closures; this is handled when
Flambda code is translated to
The following transformations are also performed during closure conversion:
- Constant blocks (by which is meant things wrapped in
Lambda.Const_block) are converted to applications of the
Leventdebugging event nodes are removed and the information within them attached to function, method and
- Tuplified functions are converted to curried functions and a stub function emitted to call the curried version. For example: let rec f (x, y) = f (x + 1, y + 1) is transformed to: let rec internal_f x y = f (x + 1,y + 1) and f (x, y) = internal_f x y (*
fis marked as a stub function *)
Prevapplyapplication primitives are removed and converted to normal
lambda_to_flambda function is not re-entrant.
