New macros, with the old contents of the functions.
* src/alloc.c (XPNTR_OR_SYMBOL_OFFSET, XPNTR):
* src/puresize.h (PURE_P, CHECK_IMPURE):
Use the new macros. Also macros, if DEFINE_KEY_OPS_AS_MACROS.

* src/emacs-module.c (plain_values): New constant.
(module_nil): Now a constant.
(Finternal_module_call, value_to_lisp_bits, lisp_to_value_bits)
(syms_of_module): Use if, not #ifdef, so that both sides are
checked at compile-time, and so that GCC doesn’t complain
about an unused var in the typical case. Also, depend on
plain_values, not on WIDE_EMACS_INT; the code shouldn’t assume
that WIDE_EMACS_INT implies !USE_LSB_TAG.
(value_to_lisp_bits, lisp_to_value_bits): New functions.
Sign-extend integers rather than zero-extending them, as small
negative integers are more likely.
(value_to_lisp, lisp_to_value): Rewrite in terms of the new *_bits
functions.
(HAVE_STRUCT_ATTRIBUTE_ALIGNED): Define to 0 if not already defined.
(mark_modules): Remove. All uses removed.
(lisp_to_value): Don’t assume Fcons returns a pointer aligned
to GCALIGNMENT.
(syms_of_module): Check that module_nil converts to Qnil.
* src/lisp.h (lisp_h_XSYMBOL, XSYMBOL): Use signed conversion, since
we prefer signed to unsigned when either will do.
(TAG_PTR): Sign-extend pointers when USE_LSB_TAG, as this is
a bit better for emacs-module.c.

(GC_XFONT_OBJECT): New macros, for use in garbage collector.
* src/alloc.c (compact_font_cache_entry, compact_font_caches):
Don't ifdef away font cache compaction on NT_GUI, as the problems
which led to that seem to have been solved.
(compact_font_cache_entry): Use GC_FONT_SPEC_P, GC_XFONT_SPEC,
GC_XFONT_ENTITY, and GC_XFONT_OBJECT, instead of their non-GC_
cousins. (Bug#21999)

This was motivated by the recent addition of module code,
which added some ENABLE_CHECKING-enabled checks that are
useful elsewhere too.
* src/alloc.c (compact_font_cache_entry):
* src/fns.c (sweep_weak_table):
* src/lread.c (oblookup):
Use gc_asize rather than doing it by hand.
* src/emacs-module.c (module_make_global_ref)
(module_free_global_ref, module_vec_size):
Omit assertions that lisp.h now checks.
* src/lisp.h (XFASTINT, ASIZE): In functional implementations,
check that the result is nonnegative. Use eassume, as this
info can help a bit when optimizing production code.
(XSYMBOL) [!USE_LSB_TAG]: Assert that argument is a symbol,
to be consistent with the USE_LSB_TAG case.
(gc_asize): New function, when ASIZE is needed in the gc.
(gc_aset): Use it.
(HASH_TABLE_P): Move definition up, so that it can be used ...
(XHASH_TABLE): ... here, to assert that the arg is a hash table.

Omit ‘#include "foo.h"’ unless the file needs foo.h (Bug#21707).
In a few cases, add ‘#include "foo.h"’ if the file needs foo.h
but does not include it directly. As a general rule, a source
file should include foo.h if it needs the interfaces that foo.h
defines.

* src/alloc.c (PURE_POINTER_P): Remove.
All uses replaced with PURE_P.
(XPNTR_OR_SYMBOL_OFFSET): New function.
(XPNTR): Move here from lisp.h.
Reimplement in terms of XPNTR_OR_SYMBOL_OFFSET.
(mark_maybe_object, valid_lisp_object_p, survives_gc_p):
Remove unnecessary cast.
(purecopy): Use XPNTR_OR_SYMBOL_OFFSET instead of XPNTR,
to avoid an unnecessary runtime test for symbols.
* src/lisp.h (lisp_h_XPNTR, XPNTR): Remove, moving XPNTR to alloc.c.
Only alloc.c needs XPNTR now.

* src/alloc.c (mark_object): Fix bug in checking code.
When GC_CHECK_MARKED_OBJECTS is defined, the bug caused
CHECK_ALLOCATED_AND_LIVE_SYMBOL to repeatedly do the
CHECK_ALLOCATED and CHECK_LIVE tests for the first symbol in each
bucket. The bug did not affect behavior either in the normal case
where GC_CHECK_MARKED_OBJECTS is not defined, or where Emacs does
not have an internal error that a properly-written
CHECK_ALLOCATED_AND_LIVE_SYMBOL would detect.

Use the same alignment for the !USE_LSB_TAG case as for the
more-typical USE_LSB_TAG case. The attempt to support arbitrary
alignments with !USE_LSB_TAG had subtle bugs in garbage collection
once we changed the representation of symbols so that Qnil == 0.
Problem reported by Eli Zaretskii (Bug#20862).
* src/alloc.c (XMALLOC_HEADER_ALIGNMENT) [XMALLOC_OVERRUN_CHECK]:
* src/alloc.c (vector_alignment, union aligned_Lisp_Symbol)
(union aligned_Lisp_Misc, maybe_lisp_pointer, pure_alloc):
Use same alignment for !USE_LSB_TAG as for USE_LSB_TAG.
* src/alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): Remove.
This optimization in the !USE_LSB_TAG case is no longer valid when
symbols are represented via offsets. Change the only use to
assume that pointers might hide in objects.
* src/lisp.h (alignas) [!USE_LSB_TAG]:
Require support in this case, too.
(TAG_SYMOFFSET, XSYMBOL) [!USE_LSB_TAG]: Do not shift the offset.
This is OK, because the !USE_LSB_TAG case now applies only when
Lisp_Object is wider than void *, so there's no longer any need
to shift the offset. Not shifting the offset means that
symbol representations have the same alignment as pointers,
which the GC assumes.

A few Emacs diagnostics go directly to stderr, and so can't easily
contain curved quotes (as non-UTF-8 locales might mishandle them).
Instead of bothering to add support for this rarity, reword the
diagnostics so that they don't use grave accent to quote.

Also, be more consistent about calls to 'Fmessage' vs 'message'.
* src/alloc.c (Fgc_status):
Prefer AUTO_STRING to build_string for Fmessage call.
* src/data.c (Fmake_variable_buffer_local)
(Fmake_local_variable, Fmake_variable_frame_local):
* src/doc.c (store_function_docstring):
Use Fmessage, not message, since the argument can contain
non-ASCII characters, and this can cause the resulting message
to be incorrectly encoded for the current environment.
* src/fns.c (maybe_resize_hash_table):
* src/xselect.c (x_clipboard_manager_save_all):
Use message, not Fmessage, since Fmessage's power isn't needed here.
* src/process.c (Fmake_network_process): Reword message to avoid %s.
* src/xdisp.c (vmessage): Document restrictions on message contents.
(message_nolog) [false]: Remove unused code.

Prefer symbol indexes to struct Lisp_Symbol * casted and then
widened, as the latter had trouble with GCC on Fedora 21 when
configured --with-wide-int and when used in static initializers.
* lib-src/make-docfile.c (write_globals): Define and use symbols like
iQnil (a small integer, like 0) rather than aQnil (an address
constant).
* src/alloc.c (garbage_collect_1, which_symbols):

All uses changed.
* src/lisp.h (TAG_SYMPTR, XSYMBOL_INIT): Remove, replacing with ...
(TAG_SYMOFFSET, SYMBOL_INDEX): ... new macros that deal with
symbol indexes rather than pointers, and which work better on MSB
hosts because they shift right before tagging. All uses changed.
(DEFINE_LISP_SYMBOL_BEGIN, DEFINE_LISP_SYMBOL_END):
No longer noops on wide-int hosts, since they work now.
(builtin_lisp_symbol): New function.

Fixes Bug#15880.
This patch also makes Q constants (e.g., Qnil) constant addresses
from the C point of view.
* make-docfile.c: Revamp to generate table of symbols, too.
Include <stdbool.h>.
(xstrdup): New function.
(main): Don't process the same file twice.
(SYMBOL): New constant in enum global_type.
(struct symbol): Turn 'value' member into a union, either v.value
for int or v.svalue for string. All uses changed.
(add_global): New arg svalue, which overrides value, so that globals
can have a string value.
(close_emacs_global): New arg num_symbols; all uses changed.
Output lispsym decl.
(write_globals): Output symbol globals too. Output more
ATTRIBUTE_CONST, now that Qnil etc. are C constants.
Output defsym_name table.
(scan_c_file): Move most of guts into ...
(scan_c_stream): ... new function. Scan for DEFSYMs and
record symbols found. Don't read past EOF if file doesn't
end in newline.
* alloc.c, bidi.c, buffer.c, bytecode.c, callint.c, casefiddle:
* casetab.c, category.c, ccl.c, charset.c, chartab.c, cmds.c, coding.c:
* composite.c, data.c, dbusbind.c, decompress.c, dired.c, dispnew.c:
* doc.c, editfns.c, emacs.c, eval.c, fileio.c, fns.c, font.c, fontset.c:
* frame.c, fringe.c, ftfont.c, ftxfont.c, gfilenotify.c, gnutls.c:
* image.c, inotify.c, insdel.c, keyboard.c, keymap.c, lread.c:
* macfont.m, macros.c, minibuf.c, nsfns.m, nsfont.m, nsimage.m:
* nsmenu.m, nsselect.m, nsterm.m, print.c, process.c, profiler.c:
* search.c, sound.c, syntax.c, term.c, terminal.c, textprop.c, undo.c:
* window.c, xdisp.c, xfaces.c, xfns.c, xftfont.c, xmenu.c, xml.c:
* xselect.c, xsettings.c, xterm.c:
Remove Q vars that represent symbols (e.g., Qnil, Qt, Qemacs).
These names are now defined automatically by make-docfile.
* alloc.c (init_symbol): New function.
(Fmake_symbol): Use it.
(c_symbol_p): New function.
(valid_lisp_object_p, purecopy): Use it.
* alloc.c (marked_pinned_symbols):
Use make_lisp_symbol instead of make_lisp_ptr.
(garbage_collect_1): Mark lispsym symbols.
(CHECK_ALLOCATED_AND_LIVE_SYMBOL): New macro.
(mark_object): Use it.
(sweep_symbols): Sweep lispsym symbols.
(symbol_uses_obj): New function.
(which_symbols): Use it. Work for lispsym symbols, too.
(init_alloc_once): Initialize Vpurify_flag here; no need to wait,
since Qt's address is already known now.
(syms_of_alloc): Add lispsym count to symbols_consed.
* buffer.c (init_buffer_once): Compare to Qnil, not to make_number (0),
when testing whether storage is all bits zero.
* dispextern (struct image_type):
* font.c (font_property_table):
* frame.c (struct frame_parm_table, frame_parms):
* keyboard.c (scroll_bar_parts, struct event_head):
* xdisp.c (struct props):
Use XSYMBOL_INIT (Qfoo) and struct Lisp_Symbol * rather than &Qfoo and
Lisp_Object *, since Qfoo is no longer an object whose address can be
taken. All uses changed.
* eval.c (run_hook): New function. Most uses of Frun_hooks changed to
use it, so that they no longer need to take the address of a Lisp sym.
(syms_of_eval): Don't use DEFSYM on Vrun_hooks, as it's a variable.
* frame.c (syms_of_frame): Add defsyms for the frame_parms table.
* keyboard.c (syms_of_keyboard): Don't DEFSYM Qmenu_bar here.
DEFSYM Qdeactivate_mark before the corresponding var.
* keymap.c (syms_of_keymap): Use DEFSYM for Qmenu_bar and Qmode_line
instead of interning their symbols; this avoids duplicates.
(LISP_INITIALLY, TAG_PTR)
(DEFINE_LISP_SYMBOL_BEGIN, DEFINE_LISP_SYMBOL_END, XSYMBOL_INIT):
New macros.
(LISP_INITIALLY_ZERO): Use it.
(enum symbol_interned, enum symbol_redirect, struct Lisp_Symbol)
(EXFUN, DEFUN_ARGS_MANY, DEFUN_ARGS_UNEVALLED, DEFUN_ARGS_*):
Move decls up, to avoid forward uses. Include globals.h earlier, too.
(make_lisp_symbol): New function.
(XSETSYMBOL): Use it.
(DEFSYM): Now just a placeholder for make-docfile.
* lread.c (DEFINE_SYMBOLS): Define, for globals.h.
(intern_sym): New function, with body taken from old intern_driver.
(intern_driver): Use it. Last arg is now Lisp integer, not ptrdiff_t.
All uses changed.
(define_symbol): New function.
(init_obarray): Define the C symbols taken from lispsym.
Use plain DEFSYM for Qt and Qnil.
* syntax.c (init_syntax_once): No need to worry about
Qchar_table_extra_slots.

(lisp_h_make_number) [USE_LSB_TAG]:
Use Lisp_Int0 instead of the mystery constant 0.
* alloc.c (mark_object): Always set and use po; that's simpler.
(CHECK_LIVE, CHECK_ALLOCATED_AND_LIVE):
Properly parenthesize definientia.

(DEFINE_GDB_SYMBOL_BEGIN): Use it.
(DEFINE_GDB_SYMBOL_BEGIN, DEFINE_GDB_SYMBOL_END) [!MAIN_PROGRAM]:
Declare the symbol, so it's visible to everywhere lisp.h is included.
Move forward decls as far forward as they can go,
to allow future changes to use them.

a hack involving a union.

These changes suffice for temacs on x86-64 with GCC 4.9.2 and
-fsanitize=address.
* alloc.c (valid_pointer_p) [ADDRESS_SANITIZER]:
Return -1 or 0, as the pipe trick doesn't work.
* alloc.c (relocatable_string_data_p, mark_object, sweep_symbols):
* data.c (Ffset):
* print.c (print_object):
When a pointer-check primitive returns -1, do not assume this
means the pointer is valid or that the underlying system has failed.
It could just be that addresses are being sanitized so Emacs can't
test for pointer validity.
* lisp.h (defined_GC_CHECK_STRING_BYTES): New constant.
(USE_STACK_STRING) [GC_CHECK_STRING_BYTES]: Now false, since the
string validity checker doesn't work on stack-based strings.

(local_cons, local_list1, local_list2, local_list3, local_list4):
Remove. Stack overflow checking makes them too slow.

users for it.
(enum LISP_STRING_OVERHEAD): Remove.
(local_string_init, local_vector_init): Remove prototypes.
