Hello UroÅ,
This simple patch fixes mode (to iterator) in
splitter for `not-xor' logic.
Bootstrapped & reg-tested on trunk.
Is it ok for trunk?
Is it ok for gcc-5-branch? (if tested accordingly)
(I have no idea how to reference to define_split in
ChangeLog entry)
gcc/
* gcc/config/i386/i386.md (define_split not/xor SWI1248x): Use
iterator instead of fixed modes..

Thanks, K
