tm.texi (ASM_WEAKEN_DECL): Document.
* doc/tm.texi (ASM_WEAKEN_DECL): Document.
(ASM_WEAKEN_LABEL): Mention ASM_WEAKEN_DECL.
(SUPPORTS_WEAK): Likewise.
* output.h (add_weak): Add tree param.
* varasm.c (add_weak): Likewise. Save decl.
(struct weak_syms): Add decl field.
(mark_weak_decls): New function.
(init_varasm_once): ggc_add_root mark_weak_decls.
(assemble_start_function): Use ASM_WEAKEN_DECL.
(assemble_variable): Likewise.
(assemble_alias): Likewise.
(declare_weak): Pass decl to add_weak.
(weak_finish): Use ASM_WEAKEN_DECL. Try to find decl.
