Progress on the #compiler. The Z8 now passes the test suite and the build coverage test. The test suite is pretty basic so there are probably plenty of bugs left. Code density is not great on the Z8 though. Also added register keywords for arguments to the compiler and split I/D to the linker.
The bytecode output for the #1802 also works with a bytecode engine in C, but the 1802 part is a long way off. Might have to stop putting off debugging the 65C816 now and carry on with #6502
