* src/alloc.c (SDATA_OF_STRING): Put cast in right spot.
This matters only if GC_CHECK_STRING_BYTES, which is sort
of a coals-to-Newcastle situation if pointer bounds checking
is also enabled.
This typically occurs in a storage manager, where the caller
is expected to access only the newly-allocated object,
instead of using the returned value to access unrelated
parts of the heap.
* src/alloc.c (allocate_string, allocate_string_data)
(compact_small_strings, find_string_data_in_pure)
(sweep_strings, setup_on_free_list, allocate_vectorlike
(pure_alloc):
* src/bytecode.c (exec_byte_code):
* src/callint.c (Fcall_interactively):
* src/dispnew.c (scrolling):
* src/editfns.c (styled_format):
* src/frame.c (xrdb_get_resource, x_get_resource_string):
* src/fringe.c (Fdefine_fringe_bitmap):
* src/gmalloc.c (malloc, realloc, aligned_alloc):
Narrow pointer bounds when appropriate.
* src/alloc.c (SDATA_OF_STRING):
* src/lisp.h (make_lisp_symbol) [__CHKP__]:
Widen bounds here, though.
* src/bytecode.c, src/callint.c, src/dispnew.c, src/editfns.c:
* src/emacs.c, src/frame.c, src/fringe.c:
Include ptr-bounds.h.
* src/ptr-bounds.h (ptr_bounds_clip): New function.
This is a minimal port, just to get Emacs running;
it does not attempt to make the pointer bounds at all tight.
* src/ptr-bounds.h: New file.
* src/alloc.c, src/gmalloc.c: Include it.
* src/alloc.c (live_string_holding, live_cons_holding)
(live_symbol_holding, live_misc_holding, garbage_collect_1)
(sweep_conses, sweep_floats):
* src/gmalloc.c (malloc_initialize_1, _free_internal_nolock)
(_realloc_internal_nolock):
Widen pointer bounds as necessary.
We're in a memory allocator so this is OK.
* src/lisp.h (lisp_h_XSYMBOL, make_lisp_symbol) [__CHKP__]:
Do not convert from pointer to integer and back again, so
that GCC does not lose track of pointer bounds.
(XSYMBOL) [__CHKP__ && !USE_LSB_TAG]: Now a compile-time error.
Although it's possible to support both -fcheck-pointer-bounds and
--with-wide-int, it's more work; keep things simple for now.
(DEFINE_LISP_SYMBOL) [__CHKP__]: Now a no-op, to avoid
trouble with unbounded pointers.
This makes Lisp_Object values opaque pointers instead of integers,
which helps avoid the same sort of typos that
CHECK_LISP_OBJECT_TYPE helps to avoid, without having to wrap
pointers inside structures. This also looks forward to supporting
-fcheck-pointer-bounds.
* etc/DEBUG:
* src/.gdbinit (Lisp_Object_Printer.to_string):
Lisp_Object can be a pointer type now.
* src/alloc.c (macro_XPNTR, XPNTR):

(lisp_h_XUNTAG) [USE_LSB_TAG]:
(XUNTAG) [!USE_LSB_TAG]:
(Lisp_Object, TAG_PTR, make_lisp_symbol):
Support new Lisp_Object implementation as a pointer to an
incomplete type. Keep pointers pointers, as much as possible.
* src/alloc.c (macro_XPNTR_OR_SYMBOL_OFFSET, XPNTR_OR_SYMBOL_OFFSET):
Remove. All uses replaced by plain XPNTR.
* src/emacs-module.c: Work around GCC bug 83162.
* src/lisp.h (LISP_WORDS_ARE_POINTERS, lisp_h_XLP, lisp_h_XPL):
(XLP, XPL) [DEFINE_KEY_OPS_AS_MACROS]:
New macros.
(Lisp_Word, untagged_ptr, Lisp_Word_tag): New types.
(XLP, XPL): New inline functions.
(TAG_PTR): Now expands to an initializer, not an expression.
All uses changed.
(TAG_SYMOFFSET, XLI_BUILTIN_LISPSYM): Remove. All uses removed.
(LISPSYM_INITIALLY): Redo in terms of the new TAG_PTR.
(NIL_IS_ZERO): Redo without XLI_BUILTIN_LISPSYM.
* src/xwidget.c (webkit_javascript_finished_cb): Use XPL
instead of XIL with a non-EMACS_INT arg.
(Fxwidget_webkit_execute_script): Use XLP instead of XLI
followed by two conversions.

* lisp/textmodes/texinfo.el (texinfo-mode):
* lisp/textmodes/mhtml-mode.el (mhtml-mode):
* lisp/progmodes/js.el (js-mode): Don't set parse-sexp-lookup-properties.
* src/json.c [WINDOWSNT]: Define fn_* function pointers to jansson
functions.
(json_delete) [WINDOWSNT]: A wrapper around fn_json_delete, needed
by json_decref.
(init_json_functions) [WINDOWSNT]: New function.
(Fjson_serialize, Fjson_insert, Fjson_parse_string)
(Fjson_parse_buffer) [WINDOWSNT]: Call init_json_functions if
needed, and record JSON in Vlibrary_cache.
* src/emacs.c (main): Don't call init_json on WINDOWSNT.
* src/w32fns.c (syms_of_w32fns): DEFSYM "json".
* lisp/term/w32-win.el (dynamic-library-alist): Add JSON DLL to
the list.
* configure.ac (HAVE_JSON): Empty JSON_LIBS for MinGW.
* nt/INSTALL.W64:
* nt/INSTALL: Add information about libjansson.
find-function-search-for-symbol will reuse the existing buffer if
we've already opened the file that contains this symbol. However, if
the user has narrowed that buffer, we can't find definitions outside
the narrowed area.
Instead, search the whole file to find definitions, and teach the help
buttons to widen if necessary.
* lisp/emacs-lisp/find-func.el (find-function-search-for-symbol):
Search the whole buffer for the target symbol.
* lisp/help-mode.el: Help buttons now widen the target buffer, if
narrowing is in effect and the target position is not in that range.
They have been deprecated for a decade now.
* src/lread.c (Fload): Don't use record_unwind_protect to warn about
old-style backquotes any more. They now generate a hard error.
(read1): Signal an error when detecting old-style backquotes. Remove
unused label.
(syms_of_lread): Remove unused internal variable
'lread--old-style-backquotes'.
(load_error_old_style_backquotes): Rename from
'load_warn_oldstyle_backquotes'. Signal an error.

from byte compiler. It isn't triggered any more.

unit test.

* lisp/calendar/cal-dst.el (calendar-dst-find-data): Do not assume
that daylight-saving time has a greater UT offset than standard
time. The reverse is true in Ireland, where standard time "IST"
is UTC +01 in summer and daylight-saving time "GMT" is UTC +00 in
winter. The current Irish rules are given by the POSIX setting
TZ='IST-1GMT0,M10.5.0,M3.5.0/1'.
