Manager of value abstractions

Valued expressions

Sourcetype 'v vexpr

Valued exprssions annotate each node in the tree of the expression with its abstract value

Sourceval empty_vexpr : 'v vexpr

Empty valued expression

Sourceval singleton_vexpr : Core.All.expr -> 'v -> 'v vexpr -> 'v vexpr

Singleton representing a leaf expression and its value

Sourceval root_vexpr : 'v vexpr -> 'v vexpr

Get the root value expressions

Sourceval add_vexpr : Core.All.expr -> 'v -> 'v vexpr -> 'v vexpr -> 'v vexpr

Attache a value to a sub-expression in a value expression

Sourceval refine_vexpr : Core.All.expr -> 'v -> 'v vexpr -> 'v vexpr

Change the value of a sub-expression in a value expression

Sourceval find_vexpr : Core.All.expr -> 'v vexpr -> 'v * 'v vexpr

Find the value of a sub-expression in a valued expression. ** Raises Not_found if the sub-expression is not found.

Sourceval find_vexpr_opt : Core.All.expr -> 'v vexpr -> ('v * 'v vexpr) option

Same as find_ctx_opt but returns None if the sub-expression is not found

Sourceval map_vexpr : ('v -> 's) -> 'v vexpr -> 's vexpr

Map the value of each sub-expression

Source

val fold_root_vexpr : 
  ('a -> Core.All.expr -> 'v -> 'v vexpr -> 'a) ->
  'a ->
  'v vexpr ->
  'a

Fold over the direct sub-expressions only

Source

val fold_vexpr : 
  ('a -> Core.All.expr -> 'v -> 'v vexpr -> 'a) ->
  'a ->
  'v vexpr ->
  'a

Fold over all sub-expression

Source

val map2_vexpr : 
  ('v -> 't) ->
  ('s -> 't) ->
  ('v -> 's -> 't) ->
  'v vexpr ->
  's vexpr ->
  't vexpr

Combine two valued expressions

Sourceval merge_vexpr : ('v -> 'v -> 'v) -> 'v vexpr -> 'v vexpr -> 'v vexpr

Combine two valued expressions

val default_backward : 
  ('v, 't) value_man ->
  Core.All.expr ->
