Simon Taylor 82c6cdb55e Make definitions of abstract types available when generating
Estimated hours taken: 100
Branches: main

Make definitions of abstract types available when generating
code for importing modules.  This is necessary for the .NET
back-end, and for `:- pragma export' on the C back-end.

compiler/prog_data.m:
compiler/modules.m:
compiler/make.dependencies.m:
compiler/recompilation.version.m:
	Handle implementation sections in interface files.

	There is a new pseudo-declaration `abstract_imported'
	which is applied to items from the implementation
	section of an interface file.  `abstract_imported'
	items may not be used in the error checking passes
	for the curent module.

compiler/equiv_type_hlds.m:
compiler/notes/compiler_design.html:
	New file.

	Go over the HLDS expanding all types fully after
	semantic checking has been run.

compiler/mercury_compile.m:
	Add the new pass.

	Don't write the `.opt' file if there are any errors.

compiler/instmap.m:
	Add a predicate instmap_delta_map_foldl to apply
	a procedure to all insts in an instmap.

compiler/equiv_type.m:
	Export predicates for use by equiv_type_hlds.m

	Reorder arguments so state variables and higher-order
	programming can be used.

compiler/prog_data.m:
compiler/prog_io_pragma.m:
compiler/make_hlds.m:
compiler/mercury_to_mercury.m:
	Handle `:- pragma foreign_type' as a form of type
	declaration rather than a pragma.

compiler/hlds_data.m:
compiler/*.m:
	Add a field to the type_info_cell_constructor cons_id
	to identify the type_ctor, which is needed by
	equiv_type_hlds.m.

compiler/module_qual.m:
	Donn't allow items from the implementation section of
	interface files to match items in the current module.

compiler/*.m:
tests/*/*.m:
	Add missing imports which only became apparent with
	the bug fixes above.

	Remove unnecessary imports which only became apparent with
	the bug fixes above.

tests/hard_coded/Mmakefile:
tests/hard_coded/export_test2.{m,exp}:
	Test case.

tests/invalid/Mmakefile:
tests/invalid/missing_interface_import2.{m,err_exp}:
	Test case.
