Well, the avr-libc's idea should not count as `recommendation' here, at least not against trying a more recent version if available. Take this rather as a minimal version to use. However, results so far for 4.0.2 aren't too exciting. It seems GCC from current CVS (which will eventually become 4.1.x) performs a lot better. > If I wanted to do some 4.0.2 experimentation, are there any > comparable patchsets to apply? So far, I didn't do any 4.x patches for avr-gcc, at least not the "newdevices" one. The patch for the 0b binary constants has been filed officially, and can now be found in GCC's bugzilla. -- cheers, J"org .-.-. --... ...-- -.. .
