For OMAP3/Cortex-A8 at least some issues are known with 2008q1: * Vectorization + NEON is broken * building static binaries with cortex-a8 flag (or any ARMv7a core) is broken * some armv6 compilations end in ICE Therefore, for Beagle & friends we recommend 2007q3. This has a known issue with -Os option, though. Dirk
