[avr-libc-dev] malloc-less i/o: small comparison

[Dmitry K.]

Hi all.

I have compared the size of two programs which contain an output
of a string into a stdout. The first uses original Avr-libc.
The second uses the modified library where the stdout connects
at a link stage, and the user is obliged to write base functions
of i/o only.

Results are (in decimal):
   text    data     bss     dec     hex filename
   1060      12      10    1082     43a ex1_old.elf
    260      16       0     276     114 ex1_new.elf

And it is without extra SRAM usage by the fdevopen/malloc
in the first case!

Dmitry.
