@ -90,28 +90,26 @@ Because of that aim, it currently builds in a particular manner.
|
||||
There are 3 build stages.
|
||||
|
||||
**Stage 0**: This stage is created with zasm by assembling `forth/forth.asm`
|
||||
through `stage0.asm`. This yields `forth0.bin`. We then wrap this binary with
|
||||
`stage.c` to create the `stage1` binary, which allows us to get to the next
|
||||
stage.
|
||||
and `z80c.bin` through `stage0.asm`. This yields `forth0.bin`. We then wrap
|
||||
this binary with `stage.c` to create the `stage1` binary, which allows us to
|
||||
get to the next stage.
|
||||
|
||||
The long term goal is to gradually extract contents from `forth.asm` and have
|
||||
nothing but Forth source files.
|
||||
`z80c.bin` is a "chicken-and-egg" typf of binary that is committed in the repo.
|
||||
It is the result of compiling `z80c.fs`, but this needs stage2.
|
||||
|
||||
**Stage 1**: The `stage1` binary allows us to augment `forth0.bin` with
|
||||
contents from `z80c.fs`, which compiles native words using Forth's Z80
|
||||
assembler. This yields `z80c.bin`.
|
||||
the compiled dictionary of a full Forth interpreter. We feed it with
|
||||
`$(FORTHSRCS)` and then dump the resulting compiled dict.
|
||||
|
||||
This is where there's a chiken-and-egg issue: Forth's assembler needs our full
|
||||
Forth interpreter, but that interpreter needs native words from `z80c.fs`. This
|
||||
is why `z80c.bin` is committed into the git repo and it's built automatically
|
||||
with `make`. Updating `z80c.bin` is a specific make rule, `fbootstrap`.
|
||||
From there, we can create `forth1.bin`, which is wrapped by both the `forth`
|
||||
and `stage2` executables. `forth` is the interpreter you'll use.
|
||||
|
||||
Then, from there, we augment `forth0.bin` with `z80c.bin` and yield
|
||||
`forth1.bin`, from which we create `stage2`.
|
||||
**Stage 2**: `stage2` is used to resolve the chicken-and-egg problem and use
|
||||
the power of a full Forth intepreter, including an assembler, to assemble
|
||||
`z80c.bin`. This is a manual step executed through `make fbootstrap`.
|
||||
|
||||
**Stage 2**: From there, the way is clear to compile the dict of our full Forth
|
||||
interpreter, which we do using `stage2` and produce `forth2.bin`, from which we
|
||||
can create our final `forth` executable.
|
||||
Normally, running this step should yield the exact same `z80c.bin` as before,
|
||||
unless of course you've changed the source.
