* * tree-flow.h (loop_only_exit_p): Declare.ebotcazou2008-07-031-0/+8
* tree-ssa-loop-niter.c (loop_only_exit_p): Make public. * tree-ssa-loop-ivopts.c (may_eliminate_iv): Reinstate direct check on the number of iterations if it is constant. Otherwise, if this is the only possible exit of the loop, use the conservative estimate on the number of iterations of the entire loop if available. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@137437 138bc75d-0d04-0410-961f-82ee72b054a4
