------- Comment #2 from kkojima at gcc dot gnu dot org 2009-06-03 00:18 -------
Currently workarounded for SH with the patch applied as revision
148018 and 148106. It defines a new DImode arithmetic shift left
expander which generates SH's movdi_i insn as its last insn.
movdi_i is a DImode move insn and expand_mult_const will mark
it with the REG_EQUAL note in the problem.
