The benchmark files can be found at http://colecovision.eu/stuff/testbench.tar.gz

¹ C6808 "C" COMPILER 3.0.0.17 - Current evaluation version as of 2012-5-12

² C Compiler for M68HC08 (COSMIC Software); Generator V4.6.3 - 05 Aug 2008; Optimizer V4.5.9 - 05 Aug 2008 - Current evaluation version as of 2012-5-12

³ ANSI-C/cC++ Compiler for HC08 V-5.0.39 Build 11346, Dec 13 2011 - Current evaluation version as of 2012-5-12

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