(vrp_visit_phi_node): Delay using SCEV till we balloon the range. (execute_vrp): Compute number of iteration estimates. * cfgloop.h (estimate_numbers_of_iterations_loop): Adjust prototype. * tree-flow.h (estimate_numbers_of_iterations): Likewise. * tree-data-ref.c (estimated_loop_iterations): Adjust. * tree-ssa-loop-niter.c (estimate_numbers_of_iterations_loop): Infer loop bounds from undefined behavior based on a new parameter. (estimate_numbers_of_iterations): Likewise. (scev_probably_wraps_p): Adjust. * tree-ssa-loop.c (tree_ssa_loop_bounds): Likewise. * gcc.dg/vect/vect-outer-fir.c: Adjust. * gcc.dg/tree-ssa/vrp54.c: New testcase. * gcc.c-torture/execute/20100827-1.c: Likewise. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@163724 138bc75d-0d04-0410-961f-82ee72b054a4 --- gcc/tree-ssa-loop.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'gcc/tree-ssa-loop.c') diff --git a/gcc/tree-ssa-loop.c b/gcc/tree-ssa-loop.c index 9523dab14dd..a62098a399b 100644 --- a/gcc/tree-ssa-loop.c +++ b/gcc/tree-ssa-loop.c @@ -458,7 +458,7 @@ tree_ssa_loop_bounds (void) if (number_of_loops () <= 1) return 0; - estimate_numbers_of_iterations (); + estimate_numbers_of_iterations (true); scev_reset (); return 0; } -- cgit v1.2.1
