Faster, slower, buggier, better ? GCC 3.4.x has a much faster implementation of floating point operations. If you are using alot of float and double, you can get much faster code. I'm using GCC-3.4.1, binutils-2.14, newlib-1.12.0, gdb/insight-5.3 and it works really great. The code gets some kilobytes larger with GCC 3.4.x than with GCC 3.3.x though. We are not using binutils-2.15 since I have experienced bugs in arm-elf-objdump. We simply cannot disassemble our elf-file. We are not using GDB-6.1.1 since I experienced that our eCos stubs uses an obsolete register setup. GDB-5.3 works fine. Maybe this is fixed in eCos HEAD, we are using the 2.0 release.
