A history of code size in sdcc and a comparison to other compilers.

STM8 code size comparison (bytes):

² C Compiler for STM8 (COSMIC Software); Generator V4.3.4 - 23 Mar 2010

³ --opt-code-size --max-allocs-per-node 2500000

This is a list of feature requests, that combined will probably get code size down near to the level of the non-free compilers.
