[Bug middle-end/21990] Wrong code for 4.0 and head: Reload clobbers the frame pointer by using it as spill register without recognizing the clobbering

I have re-investigated this bug today and observed that it no longer appears in 
mainline. It is also absent in today's cvs state of the 4.0 branch. 
 
Dunno whether the original problem has been fixed or whether something else has 
changed such that the bug is no longer exposed: Since the register allocator 
now seems to be smarter on both branches than it used to be, the function 
exposing the bug no longer needs the frame pointer. 
 
Yours,
