Re: [fpc-devel] Questions about cross-compiling (z80)
2. Is it possible to add z80 cross compilation target to FP IDE? The FP IDe shows me a few targets, but z80 is not there. The text mode IDE can only ever compile for one CPU platform, so you need to build it for Z80. Though I don't know right now whether this is enabled. I just added basic support for a few more CPUs: riscv32, riscv64, wasm32, xtensa and z80. You can generate them in newest trunk by moving to packages/ide directory and issuing a: make all_targets OPT="" with being you usual OPT. Or you can simply use: make z80 OPT="" followed by make z80_install OPT="" This should add z80-fp executable in the same location as your latest trunk compiler... Most CPUs do not have CPU specific options encoded inside the IDE sources, thus you might need to add the options you want to use to the Please report if you discover any problems.

That code should not generate more than 8 bytes of code. - no smartlinking? - any high level language comes with some overhead - begin end. is simply a bad tests. Getting rid of code any useful program needs makes little sense. - Z80 rtl is probably not optimized for size yet. E.g. on avrtiny, the smallest program is 94 bytes, most space taken by the interrupt vector table and flash to ram copying routines any program needs anyways, but in this case a lot of optimization has been spent in the compiler which Z80 didn't receive yet. Are there any flags that I need to use to make the code smaller? Cheers, BogDan.

Just for clarification of the original poster - Sven means building the IDE for _compilation_ for Z80 (not that the IDE should run on Z80). Nevertheless, even that isn't supported right now at the moment - as of now, there's support only for x86 and m68k architectures within this IDE. It might be possible to add support for other targets as well, but it would require some effort.
