Hi.
Can someone review this please?
===================================================================
Estimated hours taken: 2
Add module qualifiers to names generated by the function
std_util:type_name/1.
compiler/base_type_info.m:
compiler/polymorphism.m:
library/mercury_builtin.m:
Add module names to base_type_infos.
library/io.m:
library/term.m:
Check module names as well as type names for special cases.
Add module qualifiers to terms that represent types
(That is, when converting type_infos to terms).
library/std_util.m:
Add type_ctor_module_name/1, add an argument to
type_ctor_name_and_arity for the module name.
Add module qualifiers to the name returned by type_name.
runtime/type_info.h:
Define the offset fo type module names, add
MR_TYPECTOR_GET_HOT_MODULE_NAME and
MR_BASE_TYPEINFO_GET_TYPE_MODULE_NAME
tests/hard_coded/higher_order_type_manip.exp:
tests/hard_coded/write.exp:
tests/hard_coded/write_.exp:
Update test case expected output with module qualifiers where needed.
