1.1 anton 19:
20:
21: \ What this implementation does is this: if it sees a declaration like
22:
1.2 anton 23: \ \ something that tells it that the current library is libc
1.6 anton 24: \ \c #include <unistd.h>
1.2 anton 25: \ c-function dlseek lseek n d n -- d
1.1 anton 26:
27: \ it genererates C code similar to the following:
28:
29: \ #include <gforth.h>
1.2 anton 30: \ #include <unistd.h>
1.1 anton 31: \
1.2 anton 32: \ void gforth_c_lseek_ndn_d(void)
1.1 anton 33: \ {
34: \ Cell *sp = gforth_SP;
35: \ Float *fp = gforth_FP;
1.2 anton 36: \ long long result; /* longest type in C */
37: \ gforth_ll2d(lseek(sp[3],gforth_d2ll(sp[2],sp[1]),sp[0]),sp[3],sp[2]);
38: \ gforth_SP = sp+2;
1.1 anton 39: \ }
40:
41: \ Then it compiles this code and dynamically links it into the Gforth
42: \ system (batching and caching are future work). It also dynamically
43: \ links lseek. Performing DLSEEK then puts the function pointer of
1.2 anton 44: \ the function pointer of gforth_c_lseek_ndn_d on the stack and
45: \ calls CALL-C.
46:
1.7 anton 47: \ ToDo:
48:
49: \ Batching, caching and lazy evaluation:
50:
51: \ Batching:
52:
53: \ New words are deferred, and the corresponding C functions are
54: \ collected in one file, until the first word is EXECUTEd; then the
55: \ file is compiled and linked into the system, and the word is
56: \ resolved.
57:
58: \ Caching:
59:
60: \ Instead of compiling all this stuff anew for every execution, we
61: \ keep the files around and have an index file containing the function
62: \ names and their corresponding .so files. If the needed wrapper name
63: \ is already present, it is just linked instead of generating the
64: \ wrapper again. This is all done by loading the index file(s?),
65: \ which define words for the wrappers in a separate wordlist.
66:
67: \ The files are built in .../lib/gforth/$VERSION/libcc/ or
68: \ ~/.gforth/libcc/$HOST/.
69:
1.2 anton 70: \ other things to do:
71:
72: \ c-variable forth-name c-name
73: \ c-constant forth-name c-name
74:
1.20 anton 75: \ Todo: conversion between function pointers and xts (both directions)
76:
77: \ taking an xt and turning it into a function pointer:
78:
79: \ e.g., assume we have the xt of + and want to create a C function int
80: \ gforth_callback_plus(int, int), and then pass the pointer to that
81: \ function:
82:
83: \ There should be Forth code like this:
84: \ ] + 0 (bye)
85: \ Assume that the start of this code is START
86:
87: \ Now, there should be a C function:
88:
89: \ int gforth_callback_plus(int p1, int p2)
90: \ {
91: \ Cell *sp = gforth_SP;
92: \ Float *fp = gforth_FP;
93: \ Float *fp = gforth_FP;
94: \ Address lp = gforth_LP;
95: \ sp -= 2;
96: \ sp[0] = p1;
97: \ sp[1] = p2;
98: \ gforth_engine(START, sp, rp, fp, lp);
99: \ sp += 1;
100: \ gforth_RP = rp;
101: \ gforth_SP = sp;
102: \ gforth_FP = fp;
103: \ gforth_LP = lp;
104: \ return sp[0];
105: \ }
106:
107: \ and the pointer to that function is the C function pointer for the XT of +.
108:
109: \ Future problems:
110: \ how to combine the Forth code generation with inlining
111: \ START is not a constant across executions (when caching the C files)
112: \ Solution: make START a variable, and store into it on startup with dlsym
113:
114: \ Syntax:
115: \ callback <rettype> <params> <paramtypes> -- <rettype>

123: \ first-time word, then to the run-time word; the run-time word calls
