I really appreciate the work and care that has gone into this compiler! I'd have no other legitimate alternative for 8051 targets.

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).
