avr-size --> Size of .text, as there are not any data.
(Or avr-objcopy to binary).

Number of cycles: simulavr, set stop point ('-B' option) at exit
from main() (this is work on both: patched and unpatched avr-gcc)
and read the full report after run. (A small script makes all
above automaticaly).

P.S. I forget to attach the second file (with dummy functions).
Without ones GCC omits a big part of test.
Attach now:

void dummy1 (float x)
{
    (void)x;
}

void dummy2 (float x, float y)
{
    (void)x;
    (void)y;
}
