Hmm,
(insn:HI 144 139 140 14 (set (reg:SF 66 ctr [orig:164 
<variable>._maxSize.width ] [164])
        (reg:SF 66 ctr [162])) 252 {*movsf_hardfloat} (nil)
    (nil))

This looks like either a target problem or a reload problem.  The reason why it is hard to reduce is 
because you need the right situation to reproduce this bug, mainly using the ctr register for floating 
point which really does not work.

The 0->!h alternative should match.

Completely preventing SFmode from being placed in CTR can cause more problems,
but we can do a better job to avoid preferencing that class.  I would suggest
trying changing

"=!r,!r,m,f,f,m,!cl,!q,!r,!h,!r,!r"

to

"=!r,!r,m,f,f,m,!*cl,!*q,!r,!*h,!r,!r"

so that the register allocator does not use those special registers for
preferencing decisions.  See if that helps.

>From the dup bug:
GCC 3.3.5 doesn't get the error, so it's a regression.  GCC 4.0.x and
mainline don't get the error; it was fixed this this patch to mainline

I'm about to submit dalej's patch for the 3.4 branch, so I'll take this (the
duplicate 22081 was mine).
