tree-vrp.c (get_single_symbol): Add assert that we don't get overflowed constants as invariant part.
2017-05-09 Richard Biener <rguenther@suse.de>
* tree-vrp.c (get_single_symbol): Add assert that we don't
get overflowed constants as invariant part.
(compare_values_warnv): Add comment before the TREE_NO_WARNING
checks. Use wi::cmp instead of recursing for integer constants.
(compare_values): Just ignore whether we assumed undefined
overflow instead of failing the compare.
(extract_range_for_var_from_comparison_expr): Add comment before the
TREE_NO_WARNING sets.
(test_for_singularity): Likewise.
(extract_range_from_comparison): Do not disable optimization
when we assumed undefined overflow.
(extract_range_basic): Remove init of unused var.
