Hello!
Attached patch reverts %z handling of HImode operands back to previous
(wrong) state until better fix is found. Unfortunately, integer and
x87 operators don't agree which suffix to use for integer operands.

       * config/i386/i386.c (print_operand) ['z']: Revert handling of
       HImode operands.
Tested on x86_64-pc-linux-gnu {,-m32}, committed to mainline.
This doesn't solve the problem. You need to add the 'w' suffix for integer instructions with memory operand.

This is how %z always worked and that is excatly the reason why I try to fix this wrong behaviour.
