I am developing the DRI driver for s3 latest product DeltaChrome. XFree86 version is 4.3.0,and gcc is the default in redhat9.0, and the output of "gcc -v" is: cc version 3.2.2 20030222 (Red Hat Linux 3.2.2-5) Furthermore,if I enable -O2 flag,the FPS of quake3 can improve about 30frames. I am very curious why gcc can help to improve it so drastically? > > > > > > ------------------------------------------------------- > > This SF.Net email sponsored by Black Hat Briefings & Training. > > Attend Black Hat Briefings & Training, Las Vegas July 24-29 - > > digital self defense, top technical experts, no vendor pitches, > > unmatched networking opportunities.
