Small Device C Compiler (SDCC)

Very nice project. I would like to use it as a replacement for non free toolchains for STM8. Works already well for medium memory model and almost for large model.

Sometimes you have to look for information outside the documentation, but apart from that it's a very good tool suite for developing on z80 (the only port I tried so far).

Thank you! Just a quick note to say 'thanks' for SDCC. Despite having a few warts here and there, it's (in my mind at least) the premiere (and in a few cases, the only) C-compiler for the targets supported. Thank you for your hard and valuable work.

The best open source C compiler for Z80 and the last C compiler for z80 still being currently maintained (as all the commercial alternative have been discontinued). The code generation could improve e.g. by supporting alternate registers, undocumented z80 instructions and by increasing the number of peep hole rules applied in code optimisation. Compared to hand coded ASM the code generated still is slower and bigger, but it is quickly improving and, with the last change in parameter passing, it is starting to outperform the other commercial solutions (20 years older). The assembler is very bare bone and, due to bugs and its odd opcode notation, is not the best to integrate existing libraries in C projects. Never the less you will not find anything better among opensource C compilers for z80

My favourite C compiler for small µCs.
