[Bug tree-optimization/42586] New: load-modify-store on x86 should be \ single instruction

[andi-gcc at firstfloor dot org]

------- 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.
