Reply-to: drizzle drizzle <drizzle76 at gmail dot com>

Hi all,
      I noticed gcc 4 can estimate based on access functions, size of
data used etc in the loop. Can any body point me to any
paper/documentation related to that.

          Also is there any option which weill help dump the estimate
for different loops in a program.

thanks

ps: Sorry if this appears twice (some confusion due to a new client)
