[m-rev.] for review: two new type_ctor_reps
Zoltan Somogyi

Tue May 13 17:15:39 AEST 2003
For review by Fergus.
Zoltan.
Delete the univ type_ctor_rep, since we haven't used it in a long time,
and add two new type_ctor_reps: one for subgoals, so that they won't have
to be treated specially when deconstructed, and one for a future type,
stable_c_pointer, which is the same as c_pointer except that it guarantees
that the entire data structure it points to, directly and indirectly is
read only, which means that its values can be tabled. The intention is
to use stable_c_pointers to represent robdds.
runtime/mercury_type_info.h:
Make the change above.
runtime/mercury_construct.c:
runtime/mercury_deconstruct.c:
runtime/mercury_deep_copy_body.h:
runtime/mercury_ml_expand_body.h:
runtime/mercury_tabling.c:
runtime/mercury_unify_compare_body.h:
Handle the two new type_ctor_reps, and delete the code handling univs.
compiler/mlds_to_gcc.m:
java/runtime/TypeCtorRep.java:
library/private_builtin.m:
runtime/mercury_mcpp.h:
runtime/mercury_mcpp.cpp:
Update the list of type_ctor_reps, including fixing some old errors
in some files.
library/rtti_implementation.m:
Update the list of type_ctor_reps, and modify the routines that
interpret the RTTI accordingly.
