Hi!
Richard reported that after my PR79345 r245833 fix avr no longer builds:
../../gcc/config/avr/avr.md:1060:1: define_expand for setmemhi needs to have
match_scratch numbers above all other operands
The following patch ought to fix that, committed as obvious to trunk.
2017-03-08 Jakub Jelinek <ja...@redhat.com>
* config/avr/avr.md (setmemhi): Make sure match_dup
operand number comes before match_scratch.
