Right, that makes no sense, and neither does...

this. Will look into this if I have some time.

------- Additional Comments From pinskia at gcc dot gnu dot org 2005-02-20 00:09 -------
This looks like a reload (or a target reload) issue:
We have the following RTL:
(insn 4097 4096 4098 236 (set (reg:BI 2598)
(and:BI (ne:BI (reg/v:SI 477 [ bNotLastFrame ])
(const_int 0 [0x0]))
(subreg:BI (reg:SI 2934) 0))) 66 {*cmpsi_and_0} (nil)
(nil))
Note the subreg here. We exand it to:
(insn 5994 4096 5995 236 (set (reg:SI 2 r2) (reg:SI 131 f3 [2934])) 4 {*movsi_internal} (nil) (nil))
(insn 5995 5994 5996 236 (set (reg:SI 262 p6) (reg:SI 2 r2)) 4 {*movsi_internal} (nil) (nil))
(insn 5996 5995 4097 236 (set (reg:SI 2 r2)
(reg/v:SI 148 f20 [orig:477 bNotLastFrame ] [477])) 4 {*movsi_internal} (nil) (nil))(insn
4097 5996 4098 236 (set (reg:BI 262 p6 [2598]) (and:BI (ne:BI (reg:SI 2 r2) (const_int 0
[0x0])) (reg:BI 262 p6))) 66 {*cmpsi_and_0} (nil) (nil))
So either we have a reload issue or we have a target issue.

This seems more likely a target bug or a latent bug.
