the type being associated to the unique ID is non-null.

it.

distribution.

* abg-ir.{h,cc} (decl_base::decl_base, scope_decl::scope_decl)
(type_decl::type_decl, namespace_decl::namespace_decl): Do not
append a decl to its context from within its constructor. It's
better doing that in a function that takes shared_ptrs to decl and
context. That way we avoid memory management havoc.
(decl_base::set_scope): New private function.
(scope_decl::add_member_decl): Make this private.
(add_decl_to_scope): New function, friend of decl_base and
scope_decl.

overload.

Adjust to new type_decl and namespace_decl constructor signature.

"namespace-decl-name", as the name of namespace element.

(test1.xml): New test input.
* tests/data/test-read-write/test0.xml: Update to use 'id' as id
attribute, rather than xml:id.
* tests/data/test-read-write/test1.xml: New test.
* test-read-write.cc (struct InOutSpec): New
(main): Reorganize to give a list of input files to read and to
write to an output file, have the test read the input files, write
them, and diff the two.
* src/abg-ir.cc (namespace_decl::~namespace_decl): Add this
missing virtual constructor definition.
* src/abg-reader.cc (read_context::{get_cur_decl,pop_decl}):
Return a null pointer when the decls stack is empty.
(update_read_context): Don't try to de-reference a NULL cur_decl.
(read_input): Don't try to poke at file validity here. What was I
thinking. Really test for advance_cursor to return 1, expressing
success.
* src/abg-reader.h (read_file): Fix style.
* Makefile.am: Add tests sub-directory.
* configure.ac: Build with debugging-friendly options if the
ABIGAIL_DEBUG env variable is set. Generate tests/Makefile.
