tree-vrp.c (get_single_symbol): New function.
* tree-vrp.c (get_single_symbol): New function.
(build_symbolic_expr): Likewise.
(symbolic_range_based_on_p): New predicate.
(extract_range_from_binary_expr_1): Deal with single-symbolic ranges
for PLUS and MINUS. Do not drop symbolic ranges at the end.
(extract_range_from_binary_expr): Try harder for PLUS and MINUS if
operand is symbolic and based on the other operand.
From-SVN: r215697
