From 0450d718804aac79ea618dcdfc74bfbda0a7e66e Mon Sep 17 00:00:00 2001 From: Jan Hubicka Date: Mon, 5 Nov 2012 12:14:16 +0100 Subject: tree-ssa-loop-niter.c (find_loop_niter): Remove just_once_each_iteration_p. * tree-ssa-loop-niter.c (find_loop_niter): Remove just_once_each_iteration_p. (maybe_lower_iteration_bound): Initialize not_executed_last_iteration to NULL * tree-ssa-loop-ivcanon.c (canonicalize_loop_induction_variables): Skip just_once_each_iteration_p; record estimated bound when loop has only one likely exit; test just_once_each_iteration_p before IV canon itself.
