* | Minor CANNOT_DUMP cleanupsPaul Eggert2018-06-151-1/+1
| | | | | | | | | | | | | | | | | | | | Mostly, this avoids munging executables when CANNOT_DUMP = yes, as the munging is needed only for unexec. * configure.ac (PAXCTL_dumped, PAXCTL_notdumped) [CANNOT_DUMP]: Leave these empty. (LD_SWITCH_SYSTEM_TEMACS) [CANNOT_DUMP]: Do not append -no-pie or -nopie. * src/alloc.c (my_heap_start) [CANNOT_DUMP]: Omit; not used.

| | | | | | | | | | | | | | * src/macfont.m (macfont_set_family_cache): Restore casts to void * that were mistakenly removed in my recent change. The types in question are pointer-to-const. Problem reported by Clemens Schüller.
* | Fix building --without-x and similarEli Zaretskii2018-06-151-6/+0
| | | | | | | | | | | | * src/keyboard.c (make_lispy_focus_out): Compile it unconditionally, as it is now supported on TTYs as well. Reported by Filipp Gunbin <fgunbin@fastmail.fm>.
* | Remove Lisp_Misc_Save_ValuePaul Eggert2018-06-143-407/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This type and its associated routines are no longer used. * src/alloc.c (voidfuncptr): Move here from src/lisp.h. (free_misc, make_save_int_int_int) (make_save_obj_obj_obj_obj, make_save_ptr) (make_save_ptr_int, make_save_ptr_ptr) (make_save_funcptr_ptr_obj, make_save_memory) (free_save_value, mark_save_value): Remove. (mark_object): Remove mention of Lisp_Misc_Save_Value. * src/lisp.h (Lisp_Misc_Save_Value, SAVE_SLOT_BITS) (SAVE_VALUE_SLOTS, SAVE_TYPE_BITS, enum Lisp_Save_Type) (struct Lisp_Save_Value, SAVE_VALUEP, XSAVE_VALUE) (save_type, XSAVE_POINTER, set_save_pointer) (XSAVE_FUNCPOINTER, XSAVE_INTEGER, set_save_integer) (XSAVE_OBJECT): Remove. (union Lisp_Misc): Remove u_save_value. (voidfuncptr): Move from here to src/alloc.c. * src/print.c (print_object): Remove support for printing Lisp_Misc_Save_Value.
* | New type Lisp_Misc_PtrPaul Eggert2018-06-145-11/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a streamlined version of Lisp_Save_Value, which contains just a pointer, as that is all Lisp_Save_Values are used for any more. With the previous changes, these objects are not primarily used as save values, so just call them "Misc" rather than "Save". * src/alloc.c (make_misc_ptr): New function. (mark_object): Mark Lisp_Misc_Ptr too. * src/lisp.h (Lisp_Misc_Ptr): New constant. (struct Lisp_Misc_Ptr): New type. (make_mint_ptr, mint_ptrp, xmint_pointer): Use Lisp_Misc_Ptr, not Lisp_Save_Value. (union Lisp_Misc): Add Lisp_Misc_Ptr. * src/print.c (print_object): Print Lisp_Misc_Ptr.
* | Avoid allocating Lisp_Save_Value for arraysPaul Eggert2018-06-143-3/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | * src/alloc.c (mark_maybe_objects): New function. * src/eval.c (default_toplevel_binding) (backtrace_eval_unrewind, Fbacktrace__locals): Treat array unwindings like other miscellaneous pdl types. (record_unwind_protect_array): New function. (do_one_unbind): Free the array while unwinding. (mark_specpdl): Mark arrays directly. * src/lisp.h (SPECPDL_UNWIND_ARRAY): New constant. (union specbinding): New member unwind_array. (SAFE_ALLOCA_LISP_EXTRA): Use record_unwind_protect_array instead of make_save_memory + record_unwind_protect.
* | Avoid allocating Lisp_Save_Value for excursionsPaul Eggert2018-06-143-29/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * src/editfns.c (save_excursion_save): New arg PDL, specifying where to save the state. All uses changed. (save_excursion_restore): Args are now the marker and info rather than a pointer to a Lisp_Save_Value containing them. All uses changed. * src/eval.c (default_toplevel_binding, Fbacktrace__locals): Treat excursions like other miscellaneous pdl types. (record_unwind_protect_excursion): Save data directly into the pdl rather than creating an object on the heap. This avoids the need to allocate and free an object. (do_one_unbind, backtrace_eval_unrewind): Unwind excursions directly. (mark_specpdl): Mark excursions directly. * src/lisp.h (SPECPDL_UNWIND_EXCURSION): New constant. (union specbinding): New member unwind_excursion.
* | Just use cons in macfont_descriptor_entityPaul Eggert2018-06-141-7/+6
| | | | | | | | | | | | * src/macfont.m (macfont_descriptor_entity): Use cons instead of make_save_ptr_int, as this avoids the need for a special type and function for this one-off.
* | Avoid allocating a Lisp_Save_Value in ftfont.cPaul Eggert2018-06-141-14/+12
| | | | | | | | | | | | | | | | | | * src/ftfont.c (struct ftfont_cache_data): New member face_refcount. (ftfont_lookup_cache): Clear it when initializing. Use make_mint_ptr, since this typically avoids the need to allocate a Lisp_Save_Value as refcount is now stored elsewhere. (ftfont_open2, ftfont_close): Manipulate the reference count in the struct, not in the save object.
* | Use record_unwind_protect_ptr to avoid allocationPaul Eggert2018-06-143-15/+27
| | | | | | | | | | | | | | | | | | | | | | * src/term.c (struct tty_pop_down_menu): New type. (tty_pop_down_menu, tty_menu_show): Use it, along with record_unwind_protect_ptr, to avoid allocating a Lisp_Misc. * src/xmenu.c (struct pop_down_menu): New type. (pop_down_menu, x_menu_show): Use it, likewise. * src/xterm.c (x_cr_destroy, x_cr_export_frames): Use record_unwind_protect_pointer to avoid possibly allocating a Lisp_Misc.
* | Avoid Lisp_Misc allocation if C stack sufficesPaul Eggert2018-06-142-18/+37
| | | | | | | | | | | | | | | | | | * src/fileio.c (union read_non_regular): New type. (read_non_regular, Finsert_file_contents): Use it to avoid allocating a Lisp_Misc. * src/keymap.c (union map_keymap): New type. (map_keymap_char_table_item, map_keymap_internal): Use it to avoid allocating a Lisp_Misc.
* | Simplify init_module_assertionsPaul Eggert2018-06-141-7/+3
| | | | | | | | | | | | | | * src/emacs-module.c (init_module_assertions): Just use NULL instead of allocating a dummy on the stack and then using eassert. Practical platforms check for null pointer dereferencing nowadays, so this is good enough.
* | New mint_ptr representation for C pointersPaul Eggert2018-06-1410-39/+78
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * src/lisp.h (make_mint_ptr, mint_ptrp, xmint_pointer): New functions. * src/dbusbind.c (xd_lisp_dbus_to_dbus, Fdbus__init_bus): * src/emacs-module.c (module_free_global_ref, Fmodule_load) (module_assert_runtime, module_assert_env, value_to_lisp) (lisp_to_value, initialize_environment) (finalize_environment, finalize_runtime_unwind) (mark_modules): * src/font.c (otf_open, font_put_frame_data) (font_get_frame_data): * src/macfont.m (macfont_invalidate_family_cache) (macfont_get_family_cache_if_present) (macfont_set_family_cache): * src/nsterm.h (XNS_SCROLL_BAR): * src/nsterm.m (ns_set_vertical_scroll_bar) (ns_set_horizontal_scroll_bar): * src/w32fns.c (w32_monitor_enum) (w32_display_monitor_attributes_list): * src/xterm.c (x_cr_destroy, x_cr_export_frames): * src/xwidget.c (webkit_javascript_finished_cb) (save_script_callback, Fxwidget_webkit_execute_script) (kill_buffer_xwidgets): Use mint pointers instead of merely save pointers.
* | Also allow custom false and null when serializing to JSONJoão Távora2018-06-151-82/+113
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * doc/lispref/text.texi (Parsing JSON): Describe new arguments of json-serialize and json-insert. * src/json.c (enum json_object_type, struct json_configuration): Move up in file before first usage. (lisp_to_json_toplevel, lisp_to_json_toplevel_1, lisp_to_json): Accept a struct json_configuration*. (Fjson_serialize, Fjson_insert): Accept multiple args. (json_parse_args): Accept new boolean configure_object_type. * test/src/json-tests.el (json-serialize, json-insert): Update forward decls. (json-parse-with-custom-null-and-false-objects): Add assertions for json-serialize.
* | Support custom null and false objects when parsing JSONJoão Távora2018-06-151-54/+82
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * doc/lispref/text.texi (Parsing JSON): Describe new :null-object and :false-object kwargs to json-parse-string and json-parse-buffer. * src/json.c (struct json_configuration): New type. (json_to_lisp): Accept a struct json_configuration* param. (json_parse_args): Rename from json_parse_object_type. (Fjson_parse_string): Rework docstring. (Fjson_parse_string, Fjson_parse_buffer): Update call to json_to_lisp. (syms_of_json): Two new syms, QCnull_object and QCfalse_object. * test/src/json-tests.el (json-parse-with-custom-null-and-false-objects): New test.
* | Remove some wrong 8-byte alignment assumptionsPaul Eggert2018-06-133-66/+63
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Do not assume that 8-byte alignment suffices for all C objects, as some platforms require 16-byte alignment for some objects, and this will start to bite us as time goes on (e.g., if an Emacs module ever uses an object containing a long double, which requires 16-byte alignment on x86-64). Conversely, on !USE_LSB_TAG platforms, do not insist on aligning Lisp objects to a multiple of 8, as this is not needed for high-order tag bits. * src/alloc.c (LISP_ALIGNMENT, MALLOC_IS_LISP_ALIGNED): New constants. (XMALLOC_BASE_ALIGNMENT, XMALLOC_HEADER_ALIGNMENT): Removed. All uses replaced by LISP_ALIGNMENT. (aligned_alloc, laligned, lmalloc, lrealloc, union aligned_Lisp_Misc) (maybe_lisp_pointer, pure_alloc): Use LISP_ALIGNMENT rather than GCALIGNMENT. (aligned_alloc): Do not worry about an alignment of LISP_ALIGNMENT when MALLOC_IS_LISP_ALIGNED, as the code never uses aligned_alloc with alignment == LISP_ALIGNMENT in that case. (__alignof__): Remove. All uses removed. (MALLOC_IS_GC_ALIGNED): Remove. All uses replaced with MALLOC_IS_LISP_ALIGNED. (vector_alignment): Remove. All uses replaced with LISP_ALIGNMENT. * src/alloc.c (mark_maybe_pointer): * src/emacs-module.c (value_to_lisp_bits): Do not assume GCALIGNMENT == 1 << GCTYPEBITS, as GCALIGNMENT is 1 on !USE_LSB_TAG platforms now. * src/lisp.h (GCALIGNMENT) [!USE_LSB_TAG]: Now 1. (struct Lisp_Symbol, union vectorlike_header, struct Lisp_Cons) (struct Lisp_String): Simplify test for verifying alignment.

Fuse the body of its loop into that of reset_buffer_local_variables. (Fkill_buffer, Fkill_all_local_variables): Don't call it any more. (reset_buffer_local_variables): Make sure the buffer's local binding is swapped out before removing it from the alist (bug#30846). Call watchers before actually killing the var. * src/data.c (Fmake_local_variable): Simplify. Use swap_in_global_binding to swap out any local binding, instead of a mix of find_symbol_value followed by messing with where&found. Don't call swap_in_symval_forwarding since the currently swapped binding is never one we've modified. (Fkill_local_variable): Use swap_in_global_binding rather than messing with where&found to try and trick find_symbol_value into doing the same. * src/alloc.c (mark_localized_symbol): 'where' can't be a frame any more.

This is simpler, matches the intent better, and should help simplify future improvements. Some of these changes are to pacify gcc -Wnull-dereference, since GCC is smarter about pointers now that Emacs no longer uses __builtin_assume_aligned; these minor changes should improve code efficiency slightly. On Fedora 28 x86-64 with default optimization this patch shrinks the size of the Emacs text segment by 0.36%. * src/conf_post.h (__has_builtin, __builtin_assume_aligned): Remove; no longer used. * src/dbusbind.c (XD_OBJECT_TO_DBUS_TYPE): Pacify -Wnull-dereference by using XCAR instead of CAR_SAFE and XCDR instead of CDR_SAFE when this is safe. * src/fileio.c (Fexpand_file_name): * src/font.c (clear_font_cache): Pacify -Wnull-dereference by removing unnecessary NILP test. * src/keyboard.c (xevent_start): New function. (read_char, read_key_sequence): Pacify -Wnull-dereference by using xevent_start instead of EVENT_START. * src/lisp.h (lisp_h_XUNTAG): Remove; XUNTAG is always a macro now, since it can no longer be implemented as a function. (XUNTAG): New third argument CTYPE. All uses changed. Cast result to CTYPE * instead of using __builtin_assume_aligned. Simplify by using LISP_WORD_TAG. (LISP_WORD_TAG): New macro. (TAG_PTR): Use it. * src/menu.c (x_popup_menu_1): Pacify -Wnull-dereference by using XCAR instead of Fcar and XCDR instead of Fcdr where this is safe.
* | Simplify read_key_sequencePaul Eggert2018-06-091-68/+30
| | | | | | | | | | | | | | | | | | * src/keyboard.c (READ_KEY_ELTS): New constant. (keyremap_step, read_key_sequence): Omit BUFSIZE arg, since it's always READ_KEY_ELTS. All callers changed. (grow_bool_vector): Remove; no longer needed. (read_key_sequence): Use a bool array instead of a Lisp bool vector, since it's small and this puts less pressure on the GC.
