Hello!
(const_int 0) and (const_int 1) are never const_wide_int.
2016-04-25 Uros Bizjak <ubizjak@gmail.com>
* config/i386/predicates.md (const0_operand): Do not match
const_wide_int code.
(const1_operand): Ditto.
Bootstrapped and regression tested on x86_64-linux-gnu {,-m32}.
Committed to mainline SVN.
Uros.
