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.
