Simon Forman 400cc7dcde Partial reduction for combinator rule works after all. 
It just looked weird to me and I didn't think it through.
Once I checked it I realized it was okay.
 2020-01-30 10:25:12 -08:00
Simon Forman 8d1797c1b6 Uncovered and fixed a subtle bug in free_reg//3. 
non_alloc/1 for words that don't change the ref count of registers and can be delegated to their semantic relation.
 2020-01-29 11:04:22 -08:00
Simon Forman 95df1fda8c Cons. I should research Lisp compilers... 
I think I should emit high-level code and reduce it to actual
machine code later under whatever model (cons cell heap, etc.)

Simon Forman 26c92e9a48 Add assoc to kinda sorta track the values in the registers. 
But it doesn't update e.g. if you add two numbers, the value int(N) stays the same.

It could be modified to track the value as it computes?  But then why keep them in registers at all? Sometimes a value must arrive at runtime, eh?

Simon Forman 712dd24e88 THread through a context to track registers. 
It seems to work to allocate and free registers with a kind of reference counting
by membership in an auxilliary list.

Simon Forman b323402c9b Fix a bug in step. 
You think it would be easy to find all the places where the type tags are needed.

It didn't tag the tail list as a list.

Also, spell out bool for true cases.

Simon Forman ab0a378b56 Minor cleanup. 
I feel like I should keep the un-partially-reduced thun/4 but
you can still read it, and the reduced forms are more efficient.
(And not too much more wordy.)
 2020-01-26 16:50:49 -08:00
Simon Forman 76de590d27 Experiments with partial reduction are very promising. 
Functions become clauses like these:

    thun(symbol(rolldown), [], [C, A, B|D], [A, B, C|D]).
    thun(symbol(rolldown), [A|B], [E, C, D|F], G) :-
        thun(A, B, [C, D, E|F], G).
    thun(symbol(dupd), [], [A, B|C], [A, B, B|C]).
    thun(symbol(dupd), [A|B], [C, D|E], F) :-
        thun(A, B, [C, D, D|E], F).
    thun(symbol(over), [], [B, A|C], [A, B, A|C]).7
    thun(symbol(over), [A|B], [D, C|E], F) :-
        thun(A, B, [C, D, C|E], F).


Definitions become

    thun(symbol(of), A, D, E) :-
        append([symbol(swap), symbol(at)], A, [B|C]),
        thun(B, C, D, E).
    thun(symbol(pam), A, D, E) :-
        append([list([symbol(i)]), symbol(map)], A, [B|C]),
        thun(B, C, D, E).
    thun(symbol(popd), A, D, E) :-
        append([list([symbol(pop)]), symbol(dip)], A, [B|C]),
        thun(B, C, D, E).


These are tail-recursive and allow for better indexing so I would expect
them to be more efficient than the originals.

Notice the difference between the original thun/4 rule for definitions
and this other one that actually works.

    thun(symbol(Def),   E, Si, So) :- def(Def, Body), append(Body, E,    E o),    thun(Eo, Si, So).
    thun(symbol(Def),   E, Si, So) :- def(Def, Body), append(Body, E, [T|Eo]), thun(T, Eo, Si, So)


The latter reduces to:

    thun(symbol(A), C, F, G) :-
        def(A, B),
        append(B, C, [D|E]),
        thun(D, E, F, G).


We want something like...

    thun(symbol(B), [], A, D) :- def(B, [H|C]), thun(H, C, A, D).
    thun(symbol(A), [H|E0], Si, So) :-
        def(A, [DH|DE]),
        append(DE, [H|E0], E),
        thun(DH, E, Si, So).

But it's good enough.  The earlier version doesn't transform into
correct code:

    thun(symbol(B), D, A, A) :- def(B, C), append(C, D, []).
    thun(symbol(A), C, F, G) :- def(A, B), append(B, C, [D|E]), thun(D, E, F, G).

It would probably be good to investigate what goes wrong there.)

It doesn't seem to work right for thun/4 combinator rules either.  Dunno what's
up there.

Simon Forman e0a36eab8b Remove '==' from definitions. (Bools) 
I decided that the conceptual simplicity of omitting '==' is more useful
than the cosmetic value of keeping it.  The defs.txt file is now just one
definition per line with the first symbol giving the name.

Also, bools are literals.
