C compiler and libraries for Z80 development.
The compiler itself is loosely based on Nora Sandler's book on writing a C compiler, but with some key differences:
- The semantic analysis is bundled into IR generation.
- Uses LLVM IR.
- Uses an ANTLR4-generated parser.
- Register allocation is implemented early on as a consequence of using LLVM IR.
- Uses a bottom-up approach to register allocation.
- ANTLR4 for generating the C parser. Your distribution of choice should already have a package for ANTLR4, but you can also download from the official website.
Warning
Ubuntu's package for ANTLR4 is outdated and generates invalid C++ code. You should download the JAR from the official website and use that instead.
- GNU binutils (
--target=z80-elf) for assembling and linking. Refer to the LURe build script for an example of how to build binutils for the Z80 target, or use LURe to build it for you. - LLVM for intermediate representation.
- C90 compiler.
- A platform-agnostic implementation of the C90 standard library.
