z80 code in c++.
all z80 compilers are C (or you can use assemblers). I want to use C++.
strategy: write some C++ that optimizes beautifully (thanks, https://gcc.godbolt.org!), compile to x86, convert to z80.
it's that or write a compiler backend for z80 for llvm/clang.
$ make
Will compile game.cc to x86 assembly (on x86 platforms), compile the x86z80 tool, and run it against the assembly. This will generate game.z80 which can (in the future) be assembled into an executable for ZX spectrum.
$ make test
This will run the x86z80 translator against the test.asm file. It does not attempt to verify the output.
