This problem can be seen on powerpc-linux-gcc with the options -O1 -fPIC
-ftls-model=initial-exec -misel.
The error occurs between 172r.ira and 174r.postreload, not at 186r.dce as
previously reported.

Reverting the change in PR39254 makes the issue go away.
Any ideas?

Ok, it looks like the bug was introduced in the 4.4 branch between 4.4.2 and
4.4.4, because my old GCC 4.4.2 compiler works, but the 4.4.4 I built yesterday
after I noticed this report does not.

I don't see the problem with 4.3 .
Kyle, are you sure it doesn't happen for you with 4.4?
I use
powerpc-linux-gnuspe-gcc -Wall -W -O1 -pthread -ftls-model=initial-exec
-mcpu=8540 -fPIC -S t.c -fverbose-asm

I am not able to reproduce this with a cross-compiling GCC 4.4.3 or 4.4.4 built
from Debian sources. Configuration parameters for GCC 4.4.4 were:

Confirmed with current 4.4 branch and mainline.
-mabi=nospe -mno=spe doesn't make the problem go away; only
changing -mcpu does.
