Hi All, Special note to toolchain distribution maintainers, and people who build the toolchain themselves:
GCC 4.4.0 will soon be released (within days). One of the major new features of the 4.4 series is a new Integrated Register Allocator (IRA) for all ports, including the AVR. While some testing has shown that AVR GCC 4.4.0 still passes many of the regression tests in GCC, there has NOT been much testing or benchmarking of the AVR with the new IRA. There are still many unknowns about the code generation. Perhaps everything is just fine; perhaps there a new code generation bugs lurking. We just don't know for sure. Because of these unknowns, the WinAVR distribution will be using the 4.3.x series (4.3.3 <= version < 4.4.0) for the foreseeable future, until such testing and benchmarking can be done and it can be shown that 4.4.x is relatively safe to use for the AVR.
