toplevel: * ggc-none.c, ggc-simple.c, ggc-page.c (ggc_alloc_obj): Rename it ggc_alloc, drop second argument, never clear returned memory. * ggc-common.c (ggc_alloc_string): Use ggc_alloc. (ggc_alloc_cleared): New. * ggc.h: Prototype ggc_alloc and ggc_alloc_cleared, not ggc_alloc_obj. Remove ggc_alloc macro. (ggc_alloc_rtx, ggc_alloc_rtvec, ggc_alloc_tree): Use ggc_alloc. * rtl.c (rtvec_alloc): Clear the vector always. (rtx_alloc): Clear the first word always. Remove dirty obstack tricks (this routine is no longer a bottleneck). * tree.c (make_node): Clear the new node always. (make_tree_vec): Likewise. (tree_cons): Clear the common structure always. (build1): Likewise; also, clear TREE_COMPLEXITY. * gengenrtl.c: Use puts wherever possible. Remove extra newlines. (gendef): Clear the first word of an RTX in the generator function, irrespective of ggc_p. Initialize '0' slots to NULL. (genlegend): Don't generate obstack_alloc_rtx routine, just a thin wrapper macro around obstack_alloc. * stmt.c (expand_fixup): Use ggc_alloc. * c-typeck.c (add_pending_init): Use ggc_alloc. * emit-rtl.c (init_emit_once): Clear CONST_DOUBLE_CHAIN(tem). * varasm.c (immed_double_const): Set CONST_DOUBLE_MEM(r) to const0_rtx when it is created. (immed_real_const_1): Set CONST_DOUBLE_CHAIN(r) to NULL_RTX if we are not in a function. * tree.c (tree_class_check_failed): Make second arg an int. * tree.h: Update prototype. cp: * call.c (add_candidate): Use ggc_alloc_cleared. * decl.c (lookup_label): Likewise. * lex.c (retrofit_lang_decl): Likewise.
