lang_dump_tree.
* tree-dump.h: Rename from c-dump.h.
* c-common.h (C_TYPE_QUALS): Removed.
Move declarations for tree-dump.c interface to...
* tree.h: ... here. Remove lang_dump_tree.
* langhooks.h (struct lang_hooks_for_tree_dump): New.
(struct lang_hooks): Add tree_dump hooks.
* langhooks.c (lhd_tree_dump_dump_tree): New function.
(lhd_tree_dump_type_quals): New function.
* langhooks-def.h (lhd_tree_dump_dump_tree, lhd_tree_dump_type_quals):
Declare.
(LANG_HOOKS_INITIALIZER): Add tree_dump hooks.
* Makefile.in: Move tree-dump.o to language-independent back-end.
cp:
* cp-tree.h (CP_TYPE_QUALS): Removed.
* decl.c (cxx_init_decl_processing): Don't set lang_dump_tree.
* cp-lang.c: Set LANG_HOOKS_TREE_DUMP_DUMP_TREE_FN and
LANG_HOOKS_TREE_DUMP_TYPE_QUALS_FN.
* dump.c (cp_dump_tree): Use void* dump_info argument to match
lang-hooks prototype.
* call.c, cp-tree.h, cvt.c, decl.c, init.c, mangle.c, method.c, pt.c,
rtti.c, semantics.c, tree.c, typeck.c, typeck2.c: All references to
CP_TYPE_QUALS changed to cp_type_quals.
* Make-lang.in: References to c-dump.h changed to tree-dump.h.
(CXX_C_OBJS): Remove c-dump.o.

We need to do things this way, because we're trying to do something like
|
|
|
|
|
|
|
|
|
|
struct B : A {
|
|
|
|
|
...

|
|

extern const A tinfo_var;

|
|
|
|
|
|
|
|
|
const B tinfo_var = {...};
|
|
|
|
|
|
|
|
|
|
which is not permitted. Also, we've not necessarily seen the definition of B.
|
|
|
|
|
So we do something like the following,
|
|
|
|
|
|
|
|
|
|
extern const A tinfo_var;
|
|
|
|
|
|
|
|
|
|

|
|
|
|
|
const void *vtable_ptr;
|
|
|
|
|
const char *name;
|
|
|
|
|
};
|
|
|
|
|
struct pseudo_B {
|
|
|
|
|
pseudo_A base;
|
|
|
|
|
...
|
|
|
|
|
};
|
|
|
|
|
|
|
|
|
|
const pseudo_B proxy_tinfo_var attribute((assembler_name="tinfo_var")) =
|
|
|
|
|
{
|
|
|
|
|
{&B::vtable, "..."},
|
|
|
|
|
...
|
|
|
|
|
};
|
|
|
|
|
|
|
|
|
|
pseudo_A and pseudo_B must be layout equivalent to the real definitions in
|
|
|
|
|
the runtime. */
