* Always allow at least double-precision bignumsPaul Eggert2019-06-041-3/+3
| | | | | | | | | Without this fix, Emacs can get into a tight loop reporting a range error when calculating timestamps. * doc/lispref/numbers.texi (Integer Basics): * src/alloc.c (syms_of_alloc): Document this. * src/bignum.c (make_bignum_bits): Always allow bignums of at least twice the width of (u)intmax_t.
* Avoid backslash-newline-newline in source codePaul Eggert2019-05-221-2/+2
| | | | | | | | | | | | | | | * etc/refcards/Makefile (PDF_FRENCH): * lib-src/etags.c (LOOP_ON_INPUT_LINES): * lisp/dabbrev.el (dabbrev-check-other-buffers): * lisp/org/org-id.el (org-id-link-to-org-use-id): * lisp/org/org.el (org-support-shift-select, org-file-apps): * src/alloc.c (CHECK_ALLOCATED_AND_LIVE) (CHECK_ALLOCATED_AND_LIVE_SYMBOL): * src/frame.h (FRAME_PIXEL_WIDTH_TO_TEXT_COLS): * src/regex-emacs.c (PREFETCH_NOLIMIT): * src/window.h (WINDOW_BUFFER): Remove backslash-newline that immediately precedes another newline, as this is not the usual style and is confusing.
* Fix broken build on m68kPaul Eggert2019-05-131-52/+25
| | | | | | | | | | | | | | The GCC + valgrind fix caused the m68k build to fail (Bug#35711). Simplify string allocation a bit to make similar problems less likely in the future. * src/alloc.c (sdata, SDATA_NBYTES, SDATA_DATA) [GC_CHECK_STRING_BYTES]: Use the same implementation as with !GC_CHECK_STRING_BYTES, as the special case is no longer needed. (SDATA_ALIGN): New constant. (SDATA_SIZE): Remove this macro, replacing with ... (sdata_size): ... this new function. All uses changed. Properly account for sizes and alignments even in the m68k case, and even if GC_CHECK_STRING_BYTES is not defined.
* Rename generic x_* identifiersAlexander Gramiak2019-04-261-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * src/image.c: Rename x_* procedures to image_*. * src/frame.c: Rename x_* procedures to gui_*.

* Minor tweaks to recent UBSan-related fixPaul Eggert2019-04-251-14/+6
| | | | | | | | | | * src/alloc.c: No need to include stdalign.h; it’s pervasive. (GC_STRING_OVERRUN_COOKIE_SIZE): Align to sdata’s alignment, so that the code works even if alignof (sdata) exceeds 8. Don’t require the cookie size to be 8, as this overly fattens 32-bit platforms and one DEADBEEF should be enough. (GC_STRING_EXTRA): Omit now-unnecessary ‘verify’. (allocate_string_data): Omit unnecessary cast.
* Make sure that ‘sdata’ objects in ‘sblock’ objects are aligned.Philipp Stephani2019-04-251-2/+10
| | | | | | | | | Issue found by Clang’s UBSan. * src/alloc.c (GC_STRING_OVERRUN_COOKIE_SIZE): Increase to 8. (string_overrun_cookie): Extend accordingly. (GC_STRING_EXTRA): Ensure that it’s properly aligned for ‘sdata’. (allocate_string_data): Verify that ‘sdata’ blocks remain aligned.
* Remove --enable-checking=xmallocoverrunPaul Eggert2019-04-211-168/+1
| | | | | | | | | | | | | | It doesn’t work anymore, and these days ‘gcc -fsanitize=address’ does a better job anyway. * configure.ac: Remove the option. * configure.ac (ac_xmalloc_overrun, XMALLOC_OVERRUN_CHECK): * src/alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD) (XMALLOC_OVERRUN_CHECK_SIZE, XMALLOC_OVERRUN_SIZE_SIZE) (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer) (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc) (overrun_check_realloc, overrun_check_free): Remove. All uses removed. * etc/NEWS: Mention this.
* Remove --enablechecking=conslist configure optionPaul Eggert2019-04-211-16/+0
| | | | | | | | | * configure.ac: Remove the option. * configure.ac (ac_gc_check_cons_list, GC_CHECK_CONS_LIST): * src/alloc.c (check_cons_list) [GC_CHECK_CONS_LIST]: * src/lisp.h (lisp_h_check_cons_list, check_cons_list): Remove. All uses removed. * etc/NEWS: Mention this.
* Simplify XPNTRPaul Eggert2019-04-211-29/+3
| | | | | | | | Because XPNTR now uses ATTRIBUTE_NO_SANITIZE_UNDEFINED, it can be simplified. * src/alloc.c (macro_PNTR_ADD, PNTR_ADD, macro_XPNTR): Remove. (XPNTR): Open-code rather than using the removed macros and functions. Also, simplify by using LISP_WORD_TAG.
* Port to recent gcc -fsanitize=undefinedPaul Eggert2019-04-211-5/+1
| | | | | | | | | * src/alloc.c (XPNTR): Add ATTRIBUTE_NO_SANITIZE_UNDEFINED and remove ATTRIBUTE_UNUSED. Do not define as a macro, so that ATTRIBUTE_NO_SANITIZE_UNDEFINED works. * src/lisp.h (lisp_h_XSYMBOL): Remove. All uses removed. With recent GCC the macro does not work with -fsanitize=undefined, and the macro can be omitted as its only function is to optimize -O0.
* Fix GC_CHECK_STRING_BYTES false alarm with pdumperPaul Eggert2019-04-191-1/+1
| | | | | * src/alloc.c (string_bytes): Don’t abort on strings taken from the dumped file.
* ; * src/alloc.c (xrealloc): Fix typo.Philipp Stephani2019-04-201-1/+1

* Remove some #ifdefs for user pointers.Philipp Stephani2019-04-191-2/+0
| | | | | | | | | | | | | | | | | Even if Emacs is compiled without module support, we don't have to comment out every bit of user pointer support. Defining the basic structures and functions and detecting user pointers in switch statements is harmless, and we're already doing the same for module functions. Removing these #ifdefs makes the code a bit easier to read. * src/lisp.h (PVEC_USER_PTR, struct Lisp_User_Ptr, USER_PTRP) (XUSER_PTR): Define unconditionally. * src/data.c (Ftype_of): * src/alloc.c (cleanup_vector): * src/print.c (print_vectorlike): * src/pdumper.c (dump_vectorlike): Remove #ifdef for user pointers.
* Remove special-casing of tagged pointers.Philipp Stephani2019-04-191-11/+2
| | | | | | | | | This partially reverts commit 09b2b8a5ce5b542856f93b645db51eb11cf9855a. * src/alloc.c (mark_maybe_pointer): Remove special-casing of tagged pointers. After commit 09d746dad36e4780d379f975a84b1b076da78c50, modules no longer rely on tagged pointers.
* Allow gap before first non-Lisp pseudovec memberPaul Eggert2019-04-081-10/+10
| | | | | | | | | | | | | Problem reported by Keith David Bershatsky in: https://lists.gnu.org/r/emacs-devel/2019-04/msg00259.html Solution suggested by Stefan Monnier in: https://lists.gnu.org/r/emacs-devel/2019-04/msg00282.html * src/buffer.h (BUFFER_LISP_SIZE): Simplify by using PSEUDOVECSIZE. (BUFFER_REST_SIZE): Simplify by using VECSIZE and BUFFER_LISP_SIZE. * src/lisp.h (PSEUDOVECSIZE): Base it on the last Lisp field, not the first non-Lisp field. All callers changed. Callers without Lisp fields changed to use ALLOCATE_PLAIN_PSEUDOVECTOR. (ALLOCATE_PLAIN_PSEUDOVECTOR): New macro.
* Simpler way to export HAVE_X_WINDOWS to GDBPaul Eggert2019-03-271-0/+7
| | | | | | | | | | * src/.gdbinit: Simplify by removing dependency on globals implementation. This is useful for a future performance improvement that I have in mind. * src/alloc.c (enum defined_HAVE_X_WINDOWS, defined_HAVE_X_WINDOWS): New enum and constant. (gdb_make_enums_visible) [__GNUC__]: Use it, to make defined_HAVE_X_WINDOWS visible to GDB.
* Fix alignment bug with pure bignumsPaul Eggert2019-03-251-4/+9
| | | | | | | | Problem found on 32-bit sparc, which has stricter alignment checking than x86-64. * src/alloc.c (pure_alloc): When TYPE is negative it now specifies the negation of the required alignment of the result. (make_pure_bignum): Specify bignum limb alignment.
* Fix misuses of NULL when talking about the NUL characterStefan Monnier2019-03-211-1/+1
| | | | | | | | | | | | | | | | | | | | | | * lisp/subr.el (inhibit-null-byte-detection): Make it an obsolete alias. * src/coding.c (setup_coding_system): Use new name. (detect_coding): Rename null_byte_found => nul_byte_found. (detect_coding_system): Use new name. Rename null_byte_found => nul_byte_found. (Fdefine_coding_system_internal): Use new name. (syms_of_coding): Rename inhibit-null-byte-detection to inhibit-nul-byte-detection. * src/w16select.c (get_clipboard_data): null_char => nul_char. * src/json.c (check_string_without_embedded_nuls): Rename from check_string_without_embedded_nulls. (Fjson_parse_string): Adjust accordingly. * src/coding.h (enum define_coding_undecided_arg_index) (enum coding_attr_index): ...null_byte... => ...nul_byte.... * lisp/info.el (info-insert-file-contents, Info-insert-dir): * lisp/international/mule.el (define-coding-system): * lisp/vc/vc-git.el (vc-git--call): * doc/lispref/nonascii.texi (Lisp and Coding Systems): Use the new name.
* Use ‘const’ to clarify GC markingPaul Eggert2019-03-191-16/+14
| | | | | | | | | | | | | | | | | | | Add ‘const’ to make the GC marking code a bit clearer. This can also help the compiler in some cases, I think because GCC can now determine more often that the value of a static C variable can be cached when its address is now converted to ‘Lisp Object const *’ before escaping. * src/alloc.c (staticvec, mark_maybe_objects, mark_memory) (mark_stack, staticpro, mark_object_root_visitor) (garbage_collect_1): * src/pdumper.c (dump_ptr_referrer, dump_emacs_reloc_to_lv) (dump_emacs_reloc_to_emacs_ptr_raw, dump_root_visitor): * src/lisp.h (vcopy, struct gc_root_visitor): * src/sysdep.c (stack_overflow): * src/thread.c (mark_one_thread): * src/thread.h (struct thread_state): Use pointer-to-const instead of plain pointer in some GC-related places where either will do.
* * src/alloc.c (gcstat): Now static.Paul Eggert2019-03-041-1/+1

* Simplify list creation in C codePaul Eggert2019-03-041-24/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The main new thing here is that C code can now say ‘list (a, b, c, d, e, f)’ instead of ‘listn (CONSTYPE_HEAP, 6, a, b, c, d, e, f)’, thus relieving callers of the responsibility of counting arguments (plus, the code feels more like Lisp). The old list1 ... list5 functions remain, as they’re probably a bit faster for small lists. * src/alloc.c (cons_listn, pure_listn): New functions. (listn): Omit enum argument. All callers changed to use either new ‘list’ or ‘pure_list’ macros. * src/charset.c (Fdefine_charset_internal): * src/coding.c (detect_coding_system) (Fset_terminal_coding_system_internal): * src/frame.c (frame_size_history_add, adjust_frame_size): * src/gtkutil.c (xg_frame_set_char_size): * src/keyboard.c (command_loop_1): * src/nsfns.m (frame_geometry): * src/widget.c (set_frame_size): * src/xfaces.c (Fcolor_distance): * src/xfns.c (frame_geometry): * src/xterm.c (x_set_window_size_1): * src/xwidget.c (Fxwidget_size_request): Prefer list1i, list2i, etc. to open-coding them. * src/charset.c (Fset_charset_priority): * src/nsterm.m (append2): * src/window.c (window_list): * src/xfaces.c (Fx_list_fonts): Use nconc2 instead of open-coding it. * src/eval.c (eval_sub, backtrace_frame_apply): * src/kqueue.c (kqueue_generate_event): * src/nsterm.m (performDragOperation:): * src/pdumper.c (Fpdumper_stats): * src/w32.c (init_environment): Prefer list1, list2, etc. to open-coding them. * src/font.c (font_list_entities): Parenthesize to avoid expanding new ‘list’ macro. * src/gtkutil.c (GETSETUP): Rename from MAKE_FLOAT_PAGE_SETUP to get lines to fit. Move outside the ‘list’ call, since it’s now a macro. * src/keymap.c (Fmake_keymap): Simplify. * src/lisp.h (list, pure_list): New macros. (list1i): New function.
* Fix typo in previous changePaul Eggert2019-03-021-5/+5
| | | | | | | * src/alloc.c (memory_full_cons_threshold): Move to after definition of struct cons_block. Problem reported by Basil L. Contovounesios in: https://lists.gnu.org/r/emacs-devel/2019-03/msg00067.html
* memory_full_cons_threshold is a constantPaul Eggert2019-03-021-8/+4
| | | | | * src/alloc.c (memory_full_cons_threshold): Now const. (memory_full): Omit no-longer-needed initialization.
* Avoid staticvec duplicatesPaul Eggert2019-03-021-0/+2
| | | | | | | | * src/alloc.c (staticpro) [ENABLE_CHECKING]: Check for duplicates. * src/keyboard.c (syms_of_keyboard): Define while-no-input-ignore-events and inhibit--record-char here ... (syms_of_keyboard_for_pdumper): ... instead of here. This avoids duplicates in staticvec.
* Suppress GC stats when obviously not neededPaul Eggert2019-03-011-124/+113
| | | | | | | | | | | | | | | | | | | This should help future improvements where these stats can be bignums that do not fit into intmax_t. * src/alloc.c (struct gcstat, gcstat): New type and static var, to package up GC statistics into one C object. It replaces ... (total_free_intervals, total_intervals, total_strings) (total_free_strings, total_string_bytes, total_vectors) (total_vector_slots, total_free_vector_slots): ... these removed static vars. All uses changed. (garbage_collect_1): Accept a struct gcstat *, not a void * which was not used anymore anyway. Return a bool indicating success, instead of a Lisp object. All callers changed. (garbage_collect): New function. All C callers of Fgarbage_collect changed to use it, since none of them use the return value. Now, only Lisp code uses Fgarbage_collect. (Fgarbage_collect): No longer noinline. Cons up the return value here, not in garbage_collect_1.
* Rename CANNOT_DUMP to HAVE_UNEXECPaul Eggert2019-02-011-6/+6
| | | | | | | * configure.ac (CANNOT_DUMP): Remove. All uses removed, or changed to the negative of with_unexec. (HAVE_UNEXEC): New macro. All uses of CANNOT_DUMP changed to the negative of this macro.
* Port pdumper to older GNU/LinuxPaul Eggert2019-01-161-15/+17
| | | | | | | Problem reported by Colin Baxter in: https://lists.gnu.org/r/emacs-devel/2019-01/msg00321.html * src/alloc.c (my_heap_start): Also define if GNU_LINUX && CANNOT_DUMP && DOUG_LEA_MALLOC.

(init_eval_once_for_pdumper): new function. (init_eval_once): call it. * src/filelock.c: CANNOT_DUMP -> will_dump_p() * src/fingerprint-dummy.c: new file * src/fingerprint.h: new file * src/fns.c: CANNOT_DUMP -> will_dump_p(), etc. (weak_hash_tables): remove (hashfn_equal, hashfn_eql): un-staticify (make_hash_table): set new 'next_weak' hash table field; drop global weak_hash_tables logic. (copy_hash_table): drop global weak_hash_tables logic. (hash_table_rehash): new function. (hash_lookup, hash_put, hash_remove_from_table, hash_clear): rehash if needed.

(syms_of_keyboard): staticpro more; call pdumper syms function. * src/lisp.h: add comments throughout (gflags): declare. (will_dump_p, will_bootstrap_p, will_dump_with_pdumper_p) (dumped_with_pdumper_p, will_dump_with_unexec_p) (dumped_with_unexec_p, definitely_will_not_unexec_p): new functions.

* List lengths are always fixnums nowPaul Eggert2019-01-101-0/+13
| | | | | | | | | | | | | | | | Without this patch, it was theoretically possible for a list length to be a bignum, which means that safe-length could signal an error (due to generating a too-large bignum) contrary to its documentation. Fix things to remove the theoretical possibility, so that list lengths are always fixnums (and so that list lenghts are always ptrdiff_t values too, since that is assumed internally anyway). * src/alloc.c (Fcons): Do not allocate so many conses that a list length won’t fit into ptrdiff_t or into fixnum. This matters only on weird platforms; on typical platforms, list lengths always fit anyway. * src/fns.c (list_length, Fsafe_length, proper-list-p): Remove integer overflow checks that are no longer needed.
