The problem is in gcse.c, function replace_store_insn(), line 6294:
6293 mem = smexpr->pattern;
6294 insn = gen_move_insn (reg, SET_SRC (single_set (del)));
6295 insn = emit_insn_after (insn, del);
This code does not handle parallels and replaces only destination of an insn
pattern. "ashlsi3" pattern, as defined in i386.md also requires operand 0 and
operand 1 to match (via ix86_expand_binary_operator ()).
