PR tree-optimization/27639
PR tree-optimization/26719 * tree-vrp.c (adjust_range_with_scev): Use scev_direction and adjust call to scev_probably_wraps_p. * tree-ssa-loop-niter.c (compare_trees, convert_step_widening, used_in_pointer_arithmetic_p, convert_step): Removed. (nowrap_type_p): New function. (scev_probably_wraps_p): Rewritten. * tree-scalar-evolution.c (instantiate_parameters_1): Do not call chrec_convert if chrec_convert_aggressive might have been used. * tree-chrec.c (convert_affine_scev, chrec_convert_1, scev_direction): New functions. (chrec_convert): Changed to a wrapper over chrec_convert_1. * tree-ssa-loop-ivopts.c (idx_find_step): Use convert_affine_scev instead of convert_step. * tree-flow.h (scev_probably_wraps_p): Declaration changed. (convert_step): Declaration removed. (convert_affine_scev, nowrap_type_p, scev_direction): Declare. * gcc.dg/pr27639.c: New test. * gcc.dg/pr26719.c: New test. * gcc.dg/tree-ssa/scev-cast.c: New test. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@114057 138bc75d-0d04-0410-961f-82ee72b054a4
