[Git][cmucl/cmucl][master] 2 commits: ldb prints out Unicode characters
by Raymond Toy 30 Jan '21

30 Jan '21

Raymond Toy pushed to branch master at cmucl / cmucl Commits: 19f274f0 by Raymond Toy at 2021-01-29T17:30:03-08:00 ldb prints out Unicode characters When printing out a base-char, only the low 8 bits of the code were used. But with Unicode support, we need to take all the bits and print them out. For control codes we use the form "#\^x". (Was #\C-x, which isn't a valid supported character form.) Ascii is printed as normal "#\a", and everything else use uses "#\u+<hex>". While we're at it, we also added special cases like #\Vt that are listed in https://cmucl.org/docs/cmu-user/html/Characters.html#Characters. With this, we can print out all unicode characters in a form that can be pasted back into lisp. - - - - - 832e116a by Raymond Toy at 2021-01-30T01:54:08+00:00 Merge branch 'issue-100-ldb-base-char-printing' into 'master' ldb prints out Unicode characters See merge request cmucl/cmucl!67 - - - - - 1 changed file: - src/lisp/print.c Changes: ===================================== src/lisp/print.c ===================================== @@ -212,12 +212,15 @@ static void brief_otherimm(lispobj obj) { int type, c, idx; - char buffer[10]; type = TypeOf(obj); switch (type) { case type_BaseChar: - c = (obj >> 8) & 0xff; + /* + * A base-char should only be 16 bits long now.

[Git][cmucl/cmucl][native-image] Round up length for boxed objects and simple vector

If we don't round and we don't end on a boundary, we'll probably just print an immediate word of 0.

[Git][cmucl/cmucl][native-image] More updates

Raymond Toy pushed to branch native-image at cmucl / cmucl Commits: 8dc1b098 by Raymond Toy at 2021-01-24T09:02:12-08:00 More updates Add asm_ni as the default to dump out one object with a comment that this is not yet implemented. Fix bug in asm_list_pointer to print just one object. The car and cdr that follow can be handled as more lisp pointers or NIL. asm_function_pointer should just print one object since it's just a pointer and not a function itself. asm_other_pointer should do the same as asm_function_pointer. Add asm_instance_pointer which prints out just the pointer (with label). Add asm_simple_vector which prints out the simple vector header and length followed by all of the lispobjs in the array. Add asm_closure_header which is a simple boxed object containing only lispobjs. Add asm_complex_vector for complex vectors. But just call asm_ni for now for debugging. Update init_asmtab appropriately for the new printers. - - - - - 1 changed file: - src/lisp/save.c Changes: ===================================== src/lisp/save.c ===================================== @@ -438,6 +438,15 @@ asm_header_word(lispobj* ptr, lispobj object, FILE* f) } +int +asm_ni(lispobj* ptr, lispobj object, FILE* f) +{ + asm_label(ptr, object, f); + fprintf(f, "\t.4byte\t0x%lx\t# NOT IMPLEMENTED\n", + object); + return 1; +} + /* * Handles all objects that consists of only of lispobjs */ @@ -476,51 +485,35 @@ asm_list_pointer(lispobj* ptr, lispobj object, FILE* f) asm_label(ptr, object, f); asm_lispobj(ptr, object, f); - asm_lispobj(ptr + 1, ptr[1], f); - return 2; + return 1; } int asm_function_pointer(lispobj* ptr, lispobj object, FILE* f) { - int k; - int len = HeaderValue(object); + printf("function pointer 0x%lx\n", object); asm_label(ptr, object, f); - for (k = 0; k < 6; ++k) { - asm_lispobj(ptr, *ptr, f); - ++ptr; - } - fprintf(f, "# function code\n"); - - unsigned char *c = (unsigned char*) ptr; - - for (k = 0; k < len - 5*4; ++k) { - fprintf(f, "\t.byte\t0x%x\n", *c++); - } - - return len + 1; + asm_lispobj(ptr, object, f); + return 1; } int asm_other_pointer(lispobj* ptr, lispobj object, FILE* f) { - int len; - asm_label(ptr, object, f); asm_lispobj(ptr, object, f); - len = asmtab[TypeOf(ptr[1])](ptr + 1, ptr[1], f); - return len + 1; + return 1; } int asm_fdefn(lispobj* ptr, lispobj object, FILE* f) { - asm_label(ptr, *ptr, f); + asm_label(ptr, object, f); - asm_header_word(ptr, *ptr, f); + asm_header_word(ptr, object, f); asm_lispobj(ptr + 1, ptr[1], f); asm_lispobj(ptr + 2, ptr[2], f); @@ -529,6 +522,43 @@ asm_fdefn(lispobj* ptr, lispobj object, FILE* f) return 4; } +int +asm_instance_pointer(lispobj* ptr, lispobj object, FILE* f) +{ + asm_label(ptr, object, f); + asm_lispobj(ptr, object, f); + return 1; +} + +int +asm_simple_vector(lispobj* ptr, lispobj object, FILE* f) +{ + int k; + int len = ptr[1] >> 2; + lispobj* data = ptr + 2; + + asm_label(ptr, object, f); + asm_header_word(ptr, object, f); + asm_lispobj(ptr + 1, ptr[1], f); + + for (k = 0; k < len; ++k) { + asm_lispobj(data + k, data[k], f); + } + + return len + 2; +} + +int +asm_closure_header(lispobj* ptr, lispobj object, FILE* f) +{ + return asm_boxed(ptr, object, f); +} + +int +asm_complex_vector(lispobj* ptr, lispobj object, FILE* f) +{ + return asm_ni(ptr, object, f); +} #if 0 int @@ -627,24 +657,26 @@ init_asmtab() int k = 0; for (k = 0; k < 256; ++k) { - asmtab[k] = asm_boxed; + asmtab[k] = asm_ni; } for (k = 0; k < 32; ++k) { asmtab[type_EvenFixnum | (k << 3)] = asm_immediate; asmtab[type_FunctionPointer | (k << 3)] = asm_function_pointer; - /* OtherImmediate0 */ + asmtab[type_OtherImmediate0 | (k << 3)] = asm_ni; asmtab[type_ListPointer | (k << 3)] = asm_list_pointer; asmtab[type_OddFixnum | (k << 3)] = asm_immediate; -#if 0 asmtab[type_InstancePointer | (k << 3)] = asm_instance_pointer; -#endif - /* OtherImmediate1 */ + asmtab[type_OtherImmediate1 | (k << 3) ] = asm_ni; asmtab[type_OtherPointer | (k << 3)] = asm_other_pointer; } asmtab[type_SymbolHeader] = asm_boxed; asmtab[type_Fdefn] = asm_fdefn; + asmtab[type_InstanceHeader] = asm_boxed; + asmtab[type_SimpleVector] = asm_simple_vector; + asmtab[type_FuncallableInstanceHeader] = asm_closure_header; + asmtab[type_ComplexVector] = asm_boxed; } void View it on GitLab: https://gitlab.common-lisp.net/cmucl/cmucl/-/commit/8dc1b098315486424544033… -- View it on GitLab: https://gitlab.common-lisp.net/cmucl/cmucl/-/commit/8dc1b098315486424544033… You're receiving this email because of your account on gitlab.common-lisp.net.
