------- Comment #1 from abel at gcc dot gnu dot org 2010-06-28 15:07 -------
Confirmed. This is because we see an insn
(set (reg:SI 1 dx [237])
(subreg:SI (plus:DI (reg:DI 2 cx [orig:135 imaj ] [135])
(const_int -1 [0xffffffffffffffff])) 0))
generated by the recently added split for lea. I thought the scheduler would
see only a reg as the first operand of a subreg, thus we hit an ICE when we
assume that SUBREG_REG is actually a REG. This however seems to be legal as
several backends use fancy subreg expressions. I will recheck and then will
fix this.
