- -Os uses the same optimizations as -O2 but takes size into account, so that should be even better for small caches. From my tests -Os is sligtly faster as -O2 since you need to load less from jffs2 (less zlib stuff). regards, Koen -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.1 (Darwin) iD8DBQFEUfAsMkyGM64RGpERAg4QAJ9foVR72/3hV/YGPOXHO24kEO/sFQCdFIBx nm4+tMzQSGRs/dNCVShAFF0= =DQOO -----END PGP SIGNATURE----- _______________________________________________ maemo-developers mailing list maemo-developers@maemo.org https://maemo.org/mailman/listinfo/maemo-developers
