Re: [Fwd: Re: [avr-gcc-list] GCC-AVR Register optimisations]

[Andrew Hutchinson]

Here my input:

For starters gcc has testsuite that can be used. It's not perfect but 
its quite demanding - even if we cant do all the tests.

Do we have info on setting this up with simulator? I did have some 
instruction - once!

After than I suggest some "benchmark"  that would produce more normal 
code and also give qualitative indications of performance (size is easy, 
speed would be nice).

Finally, regression tests using testcases and bug reports.
