Sorry to answer a question with another question, but why -O3? Are you aware that on these size- and performance-restricted platforms -Os is most likely to give you the best performance due to memory I/O? The -O3 optimization adds a good bit of size that means more page faults and cache misses, which translates to slower real-world performance. _______________________________________________ openwrt-devel mailing list [email protected] https://lists.openwrt.org/mailman/listinfo/openwrt-devel
