* tree-ssa.c: Include cfgloop.h. (execute_update_addresses_taken): When updating ssa, if in loop closed SSA form, call rewrite_into_loop_closed_ssa instead of update_ssa. * Makefile.in (tree-ssa.o): Depend on $(CFGLOOP_H). * gcc.dg/pr48739-1.c: New test. * gcc.dg/pr48739-2.c: New test. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@177924 138bc75d-0d04-0410-961f-82ee72b054a4
