Breakpoint 7, combine_simplify_rtx (x=0x7ffff5ae6e58, op0_mode=VOIDmode,
in_dest=0) at /space/rguenther/src/svn/trunk/gcc/combine.c:4861
4861 enum rtx_code code = GET_CODE (x);
(set (reg:SI 69)
(and:SI (subreg:SI (ior:QI (subreg:QI (ior:SI (reg:SI 67 [ g_9 ])
(const_int 1 [0x1])) 0)
(const_int -2 [0xfffffffffffffffe])) 0)
(const_int 255 [0xff])))
(gdb) finish
Value returned is $19 = (struct rtx_def *) 0x7ffff5ae6e58
(gdb) call debug_rtx ($19)
(set (reg:SI 69)
(const_int -1 [0xffffffffffffffff]))
but combine_simplify_rtx didn't simplify the subexpressions without the
set. Hm.
