* Inline a couple of functions that were macrosPaul Eggert2020-04-25
| | | | | | | | This reclaims a bit of performance when compiling with gcc -Og. These functions were macros until I changed them in 2020-04-17T14:57:25Z!eggert@cs.ucla.edu. * src/casefiddle.c (make_char_unibyte): * src/ccl.c (GET_TRANSLATION_TABLE): Now inline.
* Prefer more inline functions in character.hPaul Eggert2020-04-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * src/buffer.h (fetch_char_advance, fetch_char_advance_no_check) (buf_next_char_len, next_char_len, buf_prev_char_len) (prev_char_len, inc_both, dec_both): New inline functions, replacing the old character.h macros FETCH_CHAR_ADVANCE, FETCH_CHAR_ADVANCE_NO_CHECK, BUF_INC_POS, INC_POS, BUF_DEC_POS, DEC_POS, INC_BOTH, DEC_BOTH respectively. All callers changed. These new functions all assume buffer primitives and so need to be here rather than in character.h. * src/casefiddle.c (make_char_unibyte): New static function, replacing the old MAKE_CHAR_UNIBYTE macro. All callers changed. (do_casify_unibyte_string): Use SINGLE_BYTE_CHAR_P instead of open-coding it. * src/ccl.c (GET_TRANSLATION_TABLE): New static function, replacing the old macro of the same name. * src/character.c (string_char): Omit 2nd arg. 3rd arg can no longer be NULL. All callers changed. * src/character.h (SINGLE_BYTE_CHAR_P): Move up. (MAKE_CHAR_UNIBYTE, MAKE_CHAR_MULTIBYTE, PREV_CHAR_BOUNDARY) (STRING_CHAR_AND_LENGTH, STRING_CHAR_ADVANCE) (FETCH_STRING_CHAR_ADVANCE) (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE) (FETCH_STRING_CHAR_ADVANCE_NO_CHECK, FETCH_CHAR_ADVANCE) (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, INC_BOTH) (DEC_BOTH, BUF_INC_POS, BUF_DEC_POS): Remove. (make_char_multibyte): New static function, replacing the old macro MAKE_CHAR_MULTIBYTE. All callers changed. (CHAR_STRING_ADVANCE): Remove; all callers changed to use CHAR_STRING. (NEXT_CHAR_BOUNDARY): Remove; it was unused. (raw_prev_char_len): New inline function, replacing the old PREV_CHAR_BOUNDARY macro. All callers changed. (string_char_and_length): New inline function, replacing the old STRING_CHAR_AND_LENGTH macro. All callers changed. (STRING_CHAR): Rewrite in terms of string_char_and_length. (string_char_advance): New inline function, replacing the old STRING_CHAR_ADVANCE macro. All callers changed. (fetch_string_char_advance): New inline function, replacing the old FETCH_STRING_CHAR_ADVANCE macro. All callers changed. (fetch_string_char_as_multibyte_advance): New inline function, replacing the old FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE macro. All callers changed. (fetch_string_char_advance_no_check): New inline function, replacing the old FETCH_STRING_CHAR_ADVANCE_NO_CHECK macro. All callers changed. * src/regex-emacs.c (HEAD_ADDR_VSTRING): Remove; no longer used. * src/syntax.c (scan_lists): Use dec_bytepos instead of open-coding it. * src/xdisp.c (string_char_and_length): Rename from string_char_and_length to avoid name conflict with new function in character.h. All callers changed.
* Remove UNSIGNED_CMPPaul Eggert2020-04-11
| | | | | | | | | | | | | | | | | | | | | | I added this macro in 2011 to fix some signedness comparison bugs. However, it’s a weird macro and the bugs can be fixed in a more-straightforward way. This helps performance slightly (0.5%) on my platform (Fedora 31 x86-64, GCC 9.3.1 with -O2). * src/casefiddle.c (do_casify_natnum): Use simple comparison instead of UNSIGNED_CMP. * src/character.h (CHAR_VALID_P, SINGLE_BYTE_CHAR_P, CHAR_STRING): * src/composite.h (COMPOSITION_ENCODE_RULE_VALID): * src/lisp.h (ASCII_CHAR_P): Now an inline function, and uses simple comparison instead of UNSIGNED_CMP. * src/dispextern.h (FACE_FROM_ID, FACE_FROM_ID_OR_NULL) (IMAGE_FROM_ID, IMAGE_OPT_FROM_ID): Move these to ... * src/frame.h (FACE_FROM_ID, FACE_FROM_ID_OR_NULL) (IMAGE_FROM_ID, IMAGE_OPT_FROM_ID): ... here, and make them inline functions that no longer use UNSIGNED_CMP. * src/keyboard.c (read_char): UNSIGNED_CMP is not needed here since XFIXNAT always returns a nonnegative value. * src/lisp.h (UNSIGNED_CMP): Remove; no longer used.

| | | | | | | | | | | | | | | | | | | | This is a followon fix for Bug#37477. * lisp/simple.el (region-extract-function): Use setq here, since the var is now defined in C code. * src/casefiddle.c (casify_pnc_region): New function. (Fupcase_region, Fdowncase_region, Fcapitalize_region) (Fupcase_initials_region): Use it. (Fupcase_initials_region): Add region-noncontiguous-p flag for consistency with the others. All uses changed. (syms_of_casefiddle): Define Qbounds, Vregion_extract_function. * src/insdel.c (prepare_to_modify_buffer_1): * src/keyboard.c (command_loop_1): Use Vregion_extraction_function. * src/insdel.c (syms_of_insdel): No need to define Qregion_extract_function. * test/src/casefiddle-tests.el (casefiddle-oldfunc): New var. (casefiddle-loopfunc, casefiddle-badfunc): New functions. (casefiddle-invalid-region-extract-function): New test.
* Support rectangular regions in capitalize-region and capitalize-dwim.Juri Linkov2019-09-22
| | | | | | | | | | * lisp/simple.el (capitalize-dwim): Add arg region-noncontiguous-p in capitalize-region call. * src/casefiddle.c (Fcapitalize_region): Add arg region-noncontiguous-p. If non-nil, operate on multiple chunks. (Bug#37477) (Fdowncase_region): Use builtin symbol Qregion_extract_function rather than calling intern.

| | | | | | | | * src/image.c (png_load_body): * src/editfns.c (styled_format): * src/casefiddle.c (do_casify_multibyte_string): * src/alloc.c (free_cons): Comment why we use a signed temporary integer variable. (Bug#37006)
* Prefer signed when testing for signed overflowPaul Eggert2019-08-11
| | | | | | | | | | * src/alloc.c (free_cons): * src/casefiddle.c (do_casify_multibyte_string): * src/editfns.c (styled_format): * src/image.c (png_load_body): Use signed arguments to INT_MULTIPLY_WRAPV etc. This doesn’t fix any bugs, but GCC emits better code when all args are signed. Also, this removes the need for an if in free_cons (Bug#37006).

* Use alignas to fix GCALIGN-related bugsPaul Eggert2017-11-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use alignas and unions to specify alignments of objects needing addresses that are at least a multiple of GCALIGNMENT. Using these standard C facilities should be safer than relying on ad hoc and poorly-understood features like GCC’s __attribute__ ((aligned (N))), the root cause for recent porting bugs like Bug#29040. The alignas macro was standardized by C11 and Gnulib supports alignas for pre-C11 platforms. I have tested this on Sun Studio 12 sparc (2007) and GCC 4.4.7 x86-64 (2012) as well as on more recent platforms like GCC 7.2.1 (2017) on Fedora 26 (both x86-64 and x86). * lib-src/make-docfile.c (close_emacs_globals): lispsym is now just an array of struct Lisp_Symbol, since struct Lisp_Symbol is now properly aligned. All uses changed. * src/alloc.c (NEXT_FREE_LISP_STRING): Just use the new u.next member; this is simpler and safer than casting a pointer that might not be aligned properly. (aligned_Lisp_Symbol): Remove. No longer needed, now that struct Lisp_Symbol is aligned properly. All uses replaced with struct Lisp_Symbol. * src/lisp.h (GCALIGNED): Remove, as it does not work as expected: it can cause the natural alignment to be ignored. All uses replaced by unions with a ‘char alignas (GCALIGNMENT)’ member as described below. (struct Lisp_Symbol, struct Lisp_Cons, struct Lisp_String): Change definition from ‘struct TAG { MEMBERS };’ to ‘struct TAG { union { struct { MEMBERS } s; char alignas (GCALIGNMENT) gcaligned; } u; };’. This guarantees ‘struct TAG’ to have an alignment that at least max (GCALIGNMENT, N) where N is its old alignment. All uses like ‘PTR->MEMBER’ changed to ‘PTR->u.s.MEMBER’; these uses were supposed to be mostly private anyway. Verify that the resulting ‘struct TAG’ is properly aligned for Emacs. (union vectorlike_header): New member ‘gcaligned’ to guarantee that this type, and its containing types like ‘struct Lisp_Subr’, ‘struct buffer’ and ‘struct thread_state’, are all properly aligned for Emacs. (struct Lisp_String): New union member ‘next’, for the benefit of NEXT_FREE_LISP_STRING. (union Aligned_Cons, union Aligned_String): Remove. All uses replaced by struct Lisp_Cons and struct Lisp_String, since they are now properly aligned. (USE_STACK_CONS, USE_STACK_STRING): Simplify now that we can assume struct Lisp_Cons and struct Lisp_String are properly aligned.
* Prefer HTTPS to FTP and HTTP in documentationPaul Eggert2017-09-13
| | | | | | | | | | | | | Most of this change is to boilerplate commentary such as license URLs. This change was prompted by ftp://ftp.gnu.org's going-away party, planned for November. Change these FTP URLs to https://ftp.gnu.org instead. Make similar changes for URLs to other organizations moving away from FTP. Also, change HTTP to HTTPS for URLs to gnu.org and fsf.org when this works, as this will further help defend against man-in-the-middle attacks (for this part I omitted the MS-DOS and MS-Windows sources and the test tarballs to keep the workload down). HTTPS is not fully working to lists.gnu.org so I left those URLs alone for now.

* Minor casefiddle.c cleanupsPaul Eggert2017-04-06
| | | | | | | | | | | | | * src/casefiddle.c: Redo recent changes to match GNU style, and prefer C99-style decls within blocks. (GREEK_CAPITAL_LETTER_SIGMA): Rename from CAPITAL_SIGMA, so that we are merely using the Unicode name, and make it a constant rather than a macro. All uses changed. (SMALL_SIGMA): Remove; unused. (GREEK_SMALL_LETTER_FINAL_SIGMA): Rename from SMALL_FINAL_SIGMA, and make it a constant rather than a macro. All uses changed. (do_casify_multibyte_string): Use ‘verify’ rather than an unportable static_assertion local.
* Implement special sigma casing rule (bug#24603)Michal Nazarewicz2017-04-06
| | | | | | | | | | | | | | | | | | In Greek, a sigma character has two lower case forms which depend on their position in the word. Implement logic determining it. * src/casefiddle.c (struct casing_context, case_character_impl): Don’t assume inword is true when flag is CASE_UP and false when flag is CASE_DOWN. For final sigma detection we need this information tracked reliably;. (CAPITAL_SIGMA, SMALL_SIGMA, SMALL_FINAL_SIGMA): New macros defining Unicode code point of different forms of sigma letter. (case_character): Implement support for final sigma casing. (do_casify_multibyte_string, do_casify_multibyte_region): Update after changes to case_character. * test/src/casefiddle-tests.el (casefiddle-tests-casing): Add test cases for final sigma.
* Support casing characters which map into multiple code points (bug#24603)Michal Nazarewicz2017-04-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement unconditional special casing rules defined in Unicode standard. Among other things, they deal with cases when a single code point is replaced by multiple ones because single character does not exist (e.g. ‘fi’ ligature turning into ‘FL’) or is not commonly used (e.g. ß turning into SS). * admin/unidata/SpecialCasing.txt: New data file pulled from Unicode standard distribution. * admin/unidata/README: Mention SpecialCasing.txt. * admin/unidata/unidata-get.el (unidata-gen-table-special-casing, unidata-gen-table-special-casing--do-load): New functions generating ‘special-uppercase’, ‘special-lowercase’ and ‘special-titlecase’ character Unicode properties built from the SpecialCasing.txt Unicode data file. * src/casefiddle.c (struct casing_str_buf): New structure for representing short strings used to handle one-to-many character mappings. (case_character_imlp): New function which can handle one-to-many character mappings. (case_character, case_single_character): Wrappers for the above functions. The former may map one character to multiple (or no) code points while the latter does what the former used to do (i.e. handles one-to-one mappings only). (do_casify_natnum, do_casify_unibyte_string, do_casify_unibyte_region): Use case_single_character. (do_casify_multibyte_string, do_casify_multibyte_region): Support new features of case_character. * (do_casify_region): Updated to reflact do_casify_multibyte_string changes. (casify_word): Handle situation when one character-length of a word can change affecting where end of the word is. (upcase, capitalize, upcase-initials): Update documentation to mention limitations when working on characters. * test/src/casefiddle-tests.el (casefiddle-tests-char-properties): Add test cases for the newly introduced character properties. (casefiddle-tests-casing): Update test cases which are now passing. * test/lisp/char-fold-tests.el (char-fold--ascii-upcase, char-fold--ascii-downcase): New functions which behave like old ‘upcase’ and ‘downcase’. (char-fold--test-match-exactly): Use the new functions. This is needed because otherwise fi and similar characters are turned into their multi- -character representation. * doc/lispref/strings.texi: Describe issue with casing characters versus strings. * doc/lispref/nonascii.texi: Describe the new character properties.
* Split up casify_region function (bug#24603)Michal Nazarewicz2017-04-06
| | | | | | | | | | No functional changes at this time but splitting casify_region into a function dealing with multibyte and another dealing with unibyte buffers will make future code changes slightly easier. * src/casefiddle.c (casify_region): Move most of the code into two new functions: (do_casify_multibyte_region, do_casify_unibyte_region): new functions.
* Add support for title-casing letters (bug#24603)Michal Nazarewicz2017-04-06
| | | | | | | | | | | * src/casefiddle.c (struct casing_context, prepare_casing_context): Add titlecase_char_table member. It’s set to the ‘titlecase’ Unicode property table if capitalisation has been requested. (case_character): Make use of the titlecase_char_table to title-case initial characters when capitalising. * test/src/casefiddle-tests.el (casefiddle-tests--characters, casefiddle-tests-casing): Update test cases which are now passing.
* Introduce case_character functionMichal Nazarewicz2017-04-06
| | | | | | | | | | | | | | Move single-character casing logic into a separate function so that it is collected in a single place. This will make future changes to the logic easier. This commit introduces no functionality changes. * src/casefiddle.c (struct casing_context, prepare_casing_context): New sturcture for saving casing context and function to initialise it. (case_character): New function which cases character base on provided context. (do_casify_integer, do_casify_multibyte_string, do_casify_unibyte_string, casify_object, casify_region): Convert to use casing_context and case_character.
* Split casify_object into multiple functionsMichal Nazarewicz2017-04-06
| | | | | | | | | | | | | | | casify_object had three major cases to cover and those were mostly independent of each other. Move those branches to separate function so it’s easier to comprehend each individual case. While at it, use somewhat more descriptive ch and cased variable names rather than c and c1. This commit introduces no functional changes. * src/casefiddle.c (casify_object): Split into… (do_casify_integer, do_casify_multibyte_string, do_casify_unibyte_string): …new functions.
* Explicit error on changing case of negative integersGlenn Morris2017-02-16
| | | | | * src/casefiddle.c (casify_object): Reject negative integers: Emacs characters are positive integers. (Bug#25684)
* casing: don’t assume letters are *either* upper- or lower-case (bug#24603)Michal Nazarewicz2017-02-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | A compatibility digraph characters, such as Dž, are neither upper- nor lower-case. At the moment however, those are reported as upper-case¹ despite the fact that they change when upper-cased. Stop checking if a character is upper-case before trying to up-case it so that title-case characters are handled correctly. This fixes one of the issues mentioned in bug#24603. ¹ Because they change when converted to lower-case. Notice an asymmetry in that for a character to be considered lower-case it must not be upper-case (plus the usual condition of changing when upper-cased). * src/buffer.h (upcase1): Delete. (upcase): Change to upcase character unconditionally just like downcase does it. This is what upcase1 was. * src/casefiddle.c (casify_object, casify_region): Use upcase instead of upcase1 and don’t check !uppercasep(x) before calling upcase. * src/keyboard.c (read_key_sequence): Don’t check if uppercase(x), just downcase(x) and see if it changed. * test/src/casefiddle-tests.el (casefiddle-tests--characters, casefiddle-tests-casing): Update test cases which are now passing.

|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Nowadays GCC is smarter, or the Emacs code has mutated, or both, and now is as good a time as any to remove uses of IF_LINT that now seem to be unnecessary. * lib-src/emacsclient.c (set_local_socket): * lib-src/movemail.c (main) [MAIL_USE_MAILLOCK && HAVE_TOUCHLOCK]: * src/buffer.c (fix_start_end_in_overlays, fix_overlays_before): * src/casefiddle.c (casify_region): * src/charset.c (load_charset_map): * src/coding.c (decode_coding_object, encode_coding_object): * src/data.c (Fmake_variable_buffer_local, Fmake_local_variable) (cons_to_unsigned, cons_to_signed): * src/frame.c (make_frame, x_set_frame_parameters): * src/keyboard.c (read_event_from_main_queue): * src/regex.c (regex_compile): * src/syntax.c (back_comment): * src/window.c (Frecenter): * src/xfaces.c (Fx_list_fonts): Remove IF_LINT that no longer seems necessary. * src/image.c (png_load_body, jpeg_load_body): Simplify use of IF_LINT. * src/keyboard.c (read_char): Use IF_LINT (volatile) rather than a pragma dance to pacify GCC -Wclobbered. * src/xdisp.c (x_produce_glyphs): Rewrite to avoid need for IF_LINT. * src/xterm.c (x_connection_closed): Now _Noreturn, which should mean we do not need IF_LINT any more. (x_io_error_quitter): Now _Noreturn. Put an 'assume (false)’ at the end, to forestall warnings from older compilers.
* Rework C source files to avoid ^(Paul Eggert2016-03-10
| | | | | | | | Work around Bug#22884 by rewording comments and strings to avoid ‘(’ at the start of a line unless it starts a function. This change is a short-term hack; in the longer run we plan to fix cc-mode’s performance for C files that have ‘(’ at the start of a line in a comment or string.
