I was recently involved in a meeting with a Freescale FAE, which informed us that the current revisions of the GNU C/C++ compilers do not yet possess any optimizations for the MPC83xx cores, more precisely no optimizations for the e300 cores inside the MPC83xx line up.
They did say it was 100% backwards compatible with the existing 603e / 6xx core support, so all the code should work just fine. I was curious if anyone out there was aware of any efforts to produce / patch any of the GNU compilers to have optimizations for these newer MPC83xx's with the e300 cores? Thanks, -Russ
