SDCC 3.7.0 was released a few days ago, and I have updated my comparison of C compilers targeting the STM8:
http://www.colecovision.eu/stm8/compilers.shtml It is just a comparison of compilers themselves - other aspects, such as IDE integration are not considered. The old comparison from 2016 ago can now be found at http://www.colecovision.eu/stm8/compilers-2016.shtml. Back in 2016, SDCC tended to generate relatively slow, big code. Now, SDCC generates the fastest code (at least for Dhrystone and Coremark) and code size also improved, with SDCC now achieving code sizes comparable to Cosmic (i.e. better than IAR, worse than Raisonance). In Summary, SDCC now wins in all categories, except for code size, where Raisonance is better (but Raisonance comes last for everything except code size, so it is only an alternative for those that care about code size only). Philipp P.S.: Still, there remins a lot to be done. Standard compliance and code speed could be improved further. Debug info and IDE integration are not perfect yet. Code size and floating-point performance need to improve (those should be obvious from teh comparison). Bugs need to be fixed. The lack of a large/huge memory model is also a big issue (SDCC 3.7.0 essentially can use only up to 32 KB of Flash for code and const data) that is already being worked on. SDCC 3.8.0, planned for later this year, will come with a large memory model (code can use the full Flash, const data would still be restricted to up to 32 KB of Flash). ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Sdcc-user mailing list Sdcc-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/sdcc-user
