Compiler optimization in GCC

#1 09-07-2008, 06:37 AM

Hello Friends,

I am planning to do my mini project as 'Experimenting with
optimization in gg platform'. I am trying to understand how
optimization happens in gcc and if possible replace a one of the
optimization algorithm with mine (say, constant propogation!)..

Can anyone give me links which helps me learn more about these.. I
have been searching around in net but most of them ends up in results
which lets one know how to use the optimizations in gcc..

Thank you.

Vivek,

Take a look at http://www.cse.iitb.ac.in/grc where you can find very
useful documentation about adding your own analysis/optimization pass
to gcc and more. A generic data flow analyzer for bit-vector
frameworks has already been implemented in gcc. (a patch will be made
available soon.)
