Compile Options for Optimized Programs

Awhile back I found some options for optimizing programs on a i686 (Athlon)
processor during compile..something along the lines of - O3 -mpcu -march do things options (environment settings I believe) ring a bell to anyone, and if so how do I impliement them? Thanks!

For optimizing your compiled apps, there are a lot of options:

-O3
-march=ARCH
-mcpu=ARCH

but there are many else. Make man gcc and go to the Optimization Options section. For enabling them just put them on the command line at compile time.

If you want to modify an existing makefile, you can set the CFLAGS and the CPPFLAGS environment variables. If you use bash, this can be done with
export CFLAGS="-option1 -option2 ..."

Hope this helps
