------- Comment #1 from rguenth at gcc dot gnu dot org 2007-06-08 10:28 -------
Confirmed. We are wrongly expanding
;; D.2027 = D.2026 << 32
(insn 18 17 0 (parallel [
(set (reg:DI 59 [ D.2027 ])
(ashift:DI (reg:DI 60 [ D.2026 ])
(const_int 32 [0x20])))
(clobber (reg:CC 17 flags))
]) -1 (nil)
(nil))
without properly truncating the result to 33 bit precision.
Not a regression.
