Sorry, I first observed this on our target. Then I tried to reproduce on x86,
but I forgot to turn on optimization flags. It does work for x86. Please delete
this report. I will figure out what happen with my target.

I found I can reproduce the bug with ARM
ARM trunk -Os:
foo:
@ args = 0, pretend = 0, frame = 0
@ frame_needed = 0, uses_anonymous_args = 0
@ link register save eliminated.
mov r2,

(In reply to comment #3)
I found I can reproduce the bug with ARM
I see this too on armv5tel-linux-gnueabi. gcc-4.4.4 -Os generates 3
instructions for the body of foo(), 4.5.1 and 4.6.0 generate 8 instructions.
