Hello Rogerio,

unfortunately bigger code is the "feature" of SDCC. I asked similar question and nobody could answer. I think that main problem is the optimization of variables in banks (at least for PIC14 port which I seldom use).

I would prefer better code optimization in SDCC as well. Currently I have to write one application which eats a lot of memory. And can not use SDCC because it can't fit into memory...

If somebody is able to optimize the SDCC code, i can test it. But I am not able to write a compiler ( or to extend it).

Vaclav
