 it is probably wise to use -O1, even though -O3 seems to work.

+BitBlt optimizations on ARM
+---------------------------
+On ARM, BitBlt optimizations can be enbaled by including --enable-fast-bitblt as an option to ../platforms/unix/config/configure (default).
+This requires the use of the assembler asasm (cf. http://lists.squeakfoundation.org/pipermail/vm-dev/2013-May/012959.html and http://forum.world.st/commit-2774-add-instructions-for-enableFastBlt-on-arm-linux-td4704245.html). 
+However it is tricky to build from source and pre-packaged versions for Raspbian, Ubuntu, etc do not seem to be available. Therefore
+asasm is included in Cog/build.linux32ARM/ as a pre-built binary. The Makefiles for BitBltPlugin and vm-display-X11 reference it directly.
