------- Comment #7 from andi-gcc at firstfloor dot org 2010-01-03 06:55 -------
This bug was not about the unnecessary stack frame, but about unnecessary
read-modify-write
(it seems you didn't read my description completely)
For stack frame probably another bug should be opened. I can do that.
I reverted the summary to the original one.
