I think the backend is responsible for most optimizations, so this
could really be arm specific. What strange behavior are you seeing?

Same here, but for AVR32. Works ok *most* of the time. Since AVR32
toolchain is quite new, it has quite a number of bugs still. Of
course, they are quite AVR32 specific. Sometimes I even get internal
compiler errors, but they go away after a retry.
