At least on x86, the load within the loop comes from reload. The pseudo that
holds the V4SF temporary (right from the beginning mind!) gets forced to memory
because of the subregs; we then reload the pseudo as necessary, which results
in the load within the loop.
With -fnew-ra, we get an ICE:
zz.c:19: internal compiler error: in subreg_hard_regno, at emit-rtl.c:1087
Assigning the bug to Michael, since the current problem can't be solved without
the new register allocator, and because of the ICE.

i686-pc-linux-gnu:
pr10469.c: In function `bad':

So this is now a regression and should be raised in priority.

No because it is not a regression for -fnew-ra at all and the other ICE that RTH produced is
reproducible with -mmmx -msse -msse2.

Micheal, does this still ICE with new-ra? Are there any progress there?

For ia32 this doesn't fail on 3.4.1, 3.4.2 and mainline as of today. I'll check
powerpc tonight.

I guess we won't ever fix this for 3.3 and new-ra is dead, so this is "fixed".
