	gcc            : ChangeLog.tree-ssa c-common.h c-semantics.c 
	                 c-simplify.c gimplify.c tree-simple.h 

Log message:
	* c-semantics.c (build_stmt): Set TREE_SIDE_EFFECTS.
	* c-simplify.c (c_gimplify_stmt): Return a gimplify_status;
	mind the status from subroutines to avoid re-gimplification.
	(c_build_bind_expr): Do not call gimplify_stmt.
	(gimplify_c_loop): Don't create a loop_expr; fully gimplify.
	(gimplify_block, gimplify_cleanup, gimplify_expr_stmt,
	gimplify_for_stmt, gimplify_while_stmt, gimplify_do_stmt,
	gimplify_if_stmt, gimplify_switch_stmt, gimplify_return_stmt,
	gimplify_decl_stmt, gimplify_compound_literal_expr,
	gimplify_stmt_expr): Return a gimplify_status.  In most cases,
	don't do local gimplification of sub-structures.
	(gimplify_decl_stmt): Use append_to_compound_expr when we care
	about the result value.
	(gimplify_stmt_expr): Use append_to_statement_list_force and
	re-gimplify so that voidify_wrapper_expr can work.
	(finish_bc_block): Don't append to a non-list.
	(c_gimplify_expr): Pass back the gimplify_status of subroutines.
	* c-common.h (c_gimplify_stmt): Update decl.
	* gimplify.c (append_to_statement_list_1): Make sure list_p is
	never null after call.
	(append_to_compound_expr): New.
	* tree-simple.h (append_to_compound_expr): Declare.
