Module Logic_typing

module Logic_typing: sig .. end
Logic typing and logic environment.
val type_rel : Logic_ptree.relation -> Cil_types.relation
Relation operators conversion
Since Nitrogen-20111001
val type_binop : Logic_ptree.binop -> Cil_types.binop
Arithmetic binop conversion. Addition and Subtraction are always considered as being used on integers. It is the responsibility of the user to introduce PlusPI/IndexPI, MinusPI and MinusPP where needed.

register_behavior_extension name f registers a typing function f to be used to type clause with name name.
