Werid it does not ICE with my tree combiner, but that is because we remove the cast to "long long".
I think there is expand problem but I could be wrong.

Note this is very hard to get a testcase which fails before 4.0 but that is because we would remove the
cast to "long long" as fold removes it.

This worked with 20041104 and 20041214's 4.0 so this is a new regression.
Before (in 20041214), we did the load the following way:
(insn 12 10 13 1 (set (reg:SI 122)
(mem/s/j:SI (reg/v/f:SI 119 [ s ]) [0 <variable>.size+0 S4 A32])) -1 (nil)
(nil))
(insn 13 12 15 1 (set (reg:SI 121)
(plus:SI (reg:SI 122)
(const_int -16 [0xfffffffffffffff0]))) -1 (nil)
(nil))
(insn 15 13 17 1 (set (reg:SI 123)
(const_int 0 [0x0])) -1 (nil)
(nil))
(insn 17 15 14 1 (clobber (reg:DI 120)) -1 (nil)
(insn_list:REG_LIBCALL 18 (nil)))
(insn 14 17 16 1 (set (subreg:SI (reg:DI 120) 4)
(reg:SI 121)) -1 (nil)
(nil))
(insn 16 14 18 1 (set (subreg:SI (reg:DI 120) 0)
(reg:SI 123)) -1 (nil)
(nil))
But now we get:
(insn 12 14 13 1 (set (subreg:SI (reg:DI 120) 4)
(plus:SI (mem/s/j:SI (reg/v/f:SI 119 [ s ]) [0 <variable>.size+0 S4 A32])
(const_int -16 [0xfffffffffffffff0]))) -1 (nil)
(nil))
(insn 13 12 15 1 (set (subreg:SI (reg:DI 120) 0)
(const_int 0 [0x0])) -1 (nil)
(nil))
So either expand is wrong for doing that or the target should understand the subreg.
