Interesting... I'd have expected getting rid of -fno-strict-aliasing gives the biggest performance boost, but I'd have expected O3 to be a bit more effective than it is... Are you sure the relevant parts actually use O3 (keep in mind that e.g. -O3 + -Os = -Os -- whatever is specified later (LOCAL_CFLAGS, ...) is effective)? Could you add another combination to the benchmark? I'm curious about -O3 -fno-inline-functions (function inlining is always a bit of a 2-edged sword because of the code size increases...) ttyl bero _______________________________________________ linaro-dev mailing list linaro-dev@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-dev
