All compilers have been configured for strong optimization for code size.

¹ C Compiler for STM8 (COSMIC Software); Generator V4.3.7; Optimizer V4.3.6. Current version as of mid-2013.

² IAR C/C++ Compiler V1.40.1.50106 for STM8. Current version as of mid-2013.

³ Compiler options --opt-code-size --max-allocs-per-node 10000000

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