Does anyone have any estimates (guesses) as to what performance gains would result from generating 64-bit grande arithmetic instructions?
If it is significant, it would seem to me to be an opportunity for some software vendor to have a tool that reads ADATA and assembler output and generates optimized assembler code for the new instructions. Sell the tool priced at a percentage of savings, and you might make some money :-) Kirk Wolf Dovetailed Technologies http://dovetail.com On Fri, Oct 9, 2009 at 12:42 AM, Timothy Sipples <[email protected]> wrote: > This COBOL discussion feels like deja vu. :-) > > As a reminder, I am not speaking for IBM. > > There have been and are lots of discussions about future COBOL innovations, > both within IBM and with our customers.
