--- Comment #10 from Jerry DeLisle <jvdelisle at gcc dot gnu.org> 2011-04-24 23:43:34 UTC --- Regarding comment #2. The patch completely eliminates this code. I did not feel confident that it is safe enough for all platforms. My approach is to first get the output correct, then we can think about optimizations later. A final fix for PR48602 will be second phase of this patch work. After that is complete, then we can re-look at any optimizations.
