>From Bjoern Haase:
Hi all,
I think that we could resolve this ICE by adding an unnamed pattern like
(define_insn "*strangeMovhi"
[(set (mem:HI (plus:HI (reg:HI 28)
(const_int 1)))
(match_operand:HI 0 "general_operand" "r"))]
""
"st %A0,y+1 \n\t st %B0,y+2"
[(set_attr "length" "2")])
to the machine description "avr.md" . That might cure the symptoms and does not
resolve the underlying problem with reload, but this might be a fix for the
immediate issue.
Note that above remark is untested pseudo-code.
Yours,
Bjoern.
P.S.: Eric, you might add this remark to the bugzilla entry.
