It worked fine until I did a rebase last month. That means dsputil.o file had size 2.1MB with debug info. For example in Commit:22180e7a5a39f8a77498fcbce54368ecc408df8f.

After the rebase onto actual master the size of dsputil.o increased to 4.7MB, which seems really wierd to me. Maybe it can be a gcc bug/feature as it is connected with optimization (--disable-optimizations reduces the size again but the speed ...). Unfortunately I can't track the commit when this situation appeared I'm only sure that the commit mentioned above is OK.

I'm using gcc 4.4.5 for arm-unknown-elf target on windows/mingw.

$ arm-unknown-elf-gcc -v
