Use max_loop_iterations in transform_to_exit_first_loop_alt
2015-06-30 Tom de Vries <tom@codesourcery.com>
PR tree-optimization/66652
* tree-parloops.c (try_transform_to_exit_first_loop_alt): Use
max_loop_iterations to determine if nit + 1 overflows.
* testsuite/libgomp.c/parloops-exit-first-loop-alt-3.c (f): Rewrite
using restrict pointers.
(main): Add arguments to calls to f.
* testsuite/libgomp.c/parloops-exit-first-loop-alt.c: Same.
* gcc.dg/parloops-exit-first-loop-alt-pr66652.c: New test.
* gcc.dg/parloops-exit-first-loop-alt-3.c (f): Rewrite using restrict
pointers.
* gcc.dg/parloops-exit-first-loop-alt.c: Same.
