	(__vtv_malloc_init): Use obstack_specify_allocation.

From-SVN: r229985

New obstack.h casts obstack_next_free to (void *), resulting in it
being a non-lvalue, and warnings on pointer arithmetic.

gcc/
	* gensupport.c (add_mnemonic_string): Make len param a size_t.
	(gen_mnemonic_setattr): Make "size" var a size_t.  Use
	obstack_blank_fast to shrink obstack.  Cast obstack_next_free
	return value.
gcc/objc/
	* objc-encoding.c (encode_aggregate_within): Cast obstack_next_free
	return value.

The code mistakenly thinks any cond_jump has two successors.  This is
not true if both destinations are the same, as can happen with weird
patterns as in the PR.


	PR rtl-optimization/68182
	* gcc/bb-reorder.c (reorder_basic_blocks_simple): Treat a conditional
	branch with only one successor just like unconditional branches.

	* tree-ssa-threadupdate.c (register_jump_thraed): Assert that a
	non-FSM path has no edges marked with EDGE_DFS_BACK.
	(ssa_redirect_edges): No longer call mark_loop_for_removal.
	(thread_single_edge, def_split_header_continue_p): Remove.
	(bb_ends_with_multiway_branch): Likewise.
	(thread_through_loop_header): Remove cases of threading from
	latch through the header.  Simplify knowing we won't thread
	the latch.
	(thread_through_all_blocks): Simplify knowing that only the FSM
	threader needs to handle backedges.
