They are _extremely_ close. The only significant enhancements on the CPU32+ vs. CPu32 were the support for misaligned transfers, and some minor tuning of the prefetch algorithm to take better advantage of the 32-bit data bus. Neither of these enhancements provide any significant opportunity for the compiler to generate better code (in fact you're going backwards with misaligned transfers), so from the compiler's point of view CPU32 and CPU32+ are identical. _______________________________________________ New CrossGCC FAQ: http://www.objsw.com/CrossGCC _______________________________________________ To remove yourself from the crossgcc list, send mail to crossgcc-request@cygnus.com with the text 'unsubscribe' (without the quotes) in the body of the message.
