expmed.c (expand_divmod): Undo sign extensions for unsigned operands
* expmed.c (expand_divmod): Undo sign extensions for unsigned operands
* cfgcleanup.c (try_forward_edges): Don't check loop structures
when not optimizing.
(cleanup_cfg): Do not iterate trought delete_trivially_dead_insns
when not expensive.
* toplev.c (rest_of_compilation): Duplicate loop headers only when
optimizing; Delete trivially dead insns early; fix optimize check.
* Makefile.in (c-decl.o, c-objc-common.o, cgraph.o, tree-inline.o): Add
dependency on cgraph.h
* c-decl.c: Include cgraph.h
(finish_function): Update call of tree_inlinable_function_p.
* c-objc-common.c: Include cgraph.h
* cgraph.h: New file.
* cgraphunit.c: New file.
* cgraph.c (cgraph_node, cgraph_edge): Move into cgraph.h
(cgraph_nodes, cgraph_n_nodes): Globalize.
(cgraph_finalize_function, cgraph_finalize_compilation_unit
cgraph_create_edges, cgraph_optimize, cgraph_mark_needed_node):
Move into cgraphunit.c
* tree-inline.c: Include cgraph.h
* tree-inline.c: Include cgraph.h
