	gcc            : ChangeLog Makefile.in c-decl.c c-lang.c 
	                 c-simplify.c c-tree.h langhooks-def.h 
	                 langhooks.c langhooks.h toplev.c tree-cfg.c 
	                 tree-optimize.c tree-optimize.h tree-simple.c 
	                 tree-ssa.c 
	gcc/testsuite/lib: c-torture.exp 

Log message:
	* Makefile.in (BOOT_CFLAGS): Remove -ftree-ssa.
	* c-decl.c (c_expand_body): Call optimize_function_tree if tree SSA
	is enabled.
	* c-lang.c (LANG_HOOKS_SIMPLIFY_FUNCTION_TREE): Define.
	* c-simplify.c (simplify_tree): Rename to c_simplify_function_tree.
	Update all callers.
	Dump function body before and after simplification if
	-fdump-tree-simple is used.
	(simplify_expr): Document FIXME for simplification of BIT_FIELD_REF
	nodes.
	* c-tree.h (simplify_tree): Rename to c_simplify_function_tree.
	* langhooks-def.h (LANG_HOOKS_SIMPLIFY_FUNCTION_TREE): Define
	(LANGHOOKS_INITIALIZER): Add LANG_HOOKS_SIMPLIFY_FUNCTION_TREE.
	(lhd_simplify_function_tree): Declare.
	* langhooks.c (lhd_simplify_function_tree): New function.
	* langhooks.h (lang_hooks): Add simplify_function_tree function
	pointer.
	* toplev.c (parse_options_and_default_flags): Set flag_tree_ssa to
	1 at optimization levels >= 1.
	Revert to default warning when -Wuninitialized is used without -O.
	* tree-cfg.c (tree_find_basic_blocks): Rename argument 't' to
	'fnbody'.
	* tree-optimize.c: Include langhooks.h.
	(optimize_tree): Rename to optimize_function_tree.  Update all
	users.
	Rename argument 't' to 'fndecl'.
	Call simplify langhook before building SSA.
	(build_tree_ssa): Rename argument 't' to 'fndecl'.
	Adjust call to tree_find_basic_blocks to pass body of the function.
	* tree-optimize.h (optimize_tree): Rename to
	optimize_function_tree.
	* tree-simple.c (is_simple_unary_expr): Document FIXME on
	BIT_FIELD_REF nodes.
	* tree-ssa.c: Add whitespace.
	* testsuite/lib/c-torture.exp: Remove -ftree-ssa flag.
