Module Wax_wasm.AstSource

WebAssembly Abstract Syntax Tree.

Sourcetype ('desc, 'info) annotated = ('desc, 'info) Wax_utils.Ast.annotated = {
  1. desc : 'desc;
  2. info : 'info;
}

An annotated tree node.

Sourcetype location = Wax_utils.Ast.location = {
  1. loc_start : Lexing.position;
  2. loc_end : Lexing.position;
}

A source code location.

Sourceval no_loc : 'desc -> ('desc, location) annotated

no_loc d creates an annotated node with a dummy location.

Sourceval dummy_loc : location

A location with dummy start/end positions, for synthesized nodes.

Sourcemodule Uint32 = Wax_utils.Uint32
Sourcemodule Uint64 = Wax_utils.Uint64

Sourcetype 'typ muttype = {

Sourcetype limits = {

  4. page_size_log2 : int option;
  5. shared : bool;
}
Sourcemodule type TYPES = sig ... end

The set of types produced by Make_types, abstracted over the index and array-wrapper representations. Naming it lets Map_types map the whole family from one instance to another.

Sourcemodule Make_types (X : sig ... end) : TYPES with type idx = X.idx and type 'a annotated_array = 'a X.annotated_array and type 'a opt_annotated_array = 'a X.opt_annotated_array
Sourcemodule Map_types_spine (Src : TYPES) (Dst : TYPES) (M : sig ... end) : sig ... end

Map the heaptype/reftype/valtype/storagetype/fieldtype family from one Make_types instance to another. Only the idx-carrying arms differ between instances; everything else is copied through. ctx is threaded to M.idx so a mapper that resolves or renames indices can carry its context (a name map, a symbol table, …).

Sourcemodule Map_types (Src : TYPES) (Dst : TYPES) (M : sig ... end) : sig ... end

Extends Map_types_spine to the whole type family. The array wrappers differ per instance, so the caller supplies how to map each one; the functype/comptype/subtype/rectype structure is copied through.
