Actually it is not an ABI change as the 3.4's RTL looks like:
(insn 3 2 4 (set (reg/v:TI 340 [ v ])
(reg:TI 136 f8 [ v ])) -1 (nil)
(nil))
so it comes in as f8.
Note 4.0.3 20051105 fails the same way as your 4.0.3 does
So closing as fixed as this is not a regression.
Note gcc 4.1 produces the RTL as:
(insn 6 11 7 0 (set (reg:XF 340)
(reg:XF 136 f8 [ v ])) -1 (nil)
(nil))
Which is in the correct mode right away.
