[En-Nut-Discussion] Code space or AVR / ARM 32 / ARM thumb

[ivesworking]

i know somel people doing compare on compiler generating code size,
like
http://www.usbdip.de/en/ethernut2294/index.html
and some info on mailling list at jan

i just want people to confirm that if i change the compiler i can get 10-20% 
smaller code size ?
anyway i using winavr at this moment,

also, if migrate to ARM/Thumb from avr, will my code size gain ?
i know this is case to case, but anyone can give a brief info on your case ?
