| | | | | | | | | | | | | | * alloc.c (ignore_warnings, init_intervals, init_float) (init_cons, init_symbol, init_marker): Remove. (interval_block_index): Initialize to INTERVAL_BLOCK_SIZE. (float_block_index): Initialize to FLOAT_BLOCK_SIZE. (cons_block_index): Initialize to CONS_BLOCK_SIZE. (symbol_block_size): Initialize to SYMBOL_BLOCK_SIZE. (marker_block_index): Initialize to MARKER_BLOCK_SIZE. (staticidx, init_alloc_once, init_strings, free_ablock): Remove redundant initialization. * fns.c (init_weak_hash_tables): Remove. * lisp.h (init_weak_hash_tables): Remove prototype.
* Use zero_vector where appropriate.Dmitry Antipov2012-07-151-4/+3
| | | | | | | | | | * alloc.c (zero_vector): Define as Lisp_Object. Adjust users accordingly. * lisp.h (zero_vector): New declaration. * font.c (null_vector): Remove. (syms_of_font): Remove initialization and staticpro. (font_list_entities, font_find_for_lface): Change to use zero_vector. * keymap.c (Faccessible_keymaps): Likewise.

| | | | attribute, so we only use it if it exists in the compiler.
* EMACS_TIME simplification (Bug#11875).Paul Eggert2012-07-101-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This replaces macros (which typically do not work in GDB) with functions, typedefs and enums, making the code easier to debug. The functional style also makes code easier to read and maintain. * lib-src/profile.c (TV2): Remove no-longer-needed static var. * src/systime.h: Include <sys/time.h> on all hosts, not just if WINDOWSNT, since 'struct timeval' is needed in general. (EMACS_TIME): Now a typedef, not a macro. (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants, not macros. (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P) (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE, EMACS_TIME_EQ) (EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE, EMACS_TIME_LT) (EMACS_TIME_LE): Now functions, not macros. (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS) (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros, which are not functions. All uses rewritten to use: (make_emacs_time): New function. (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME) (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are not functions. All uses rewritten to use the following, respectively: (emacs_secs_addr, invalid_emacs_time, get_emacs_time) (add_emacs_time, sub_emacs_time): New functions. * src/atimer.c: Don't include <sys/time.h>, as "systime.h" does this. * src/fileio.c (Fcopy_file): * src/xterm.c (XTflash): Get the current time closer to when it's used. * src/makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.
* Optimize pure C strings initialization.Dmitry Antipov2012-07-101-5/+4
| | | | | | | | | | | | | * lisp.h (make_pure_string): Fix prototype. (build_pure_c_string): New function, defined as static inline. This provides a better opportunity to optimize away calls to strlen when the function is called with compile-time constant argument. * alloc.c (make_pure_c_string): Fix comment. Change to add nchars argument, adjust users accordingly. Use build_pure_c_string where appropriate. * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c, * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c, * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
* Minor improvements to make_formatted_string.Paul Eggert2012-07-091-1/+1
| | | | | | * alloc.c (make_formatted_string): Prefer int to ptrdiff_t where int is good enough, as vsprintf returns an int. * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.

| | | | | | | | | | | | | | | | | | | | | | | | * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c: * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c: * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, fns.c: * font.c, fontset.c, frame.c, fringe.c, ftfont.c, ftxfont.c, gmalloc.c: * gtkutil.c, image.c, keyboard.c, keymap.c, lread.c, macros.c, menu.c: * nsfns.m, nsfont.m, nsmenu.m, nsterm.m, print.c, process.c, ralloc.c: * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c: * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c: * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c: * xterm.c: Omit needless casts involving void * pointers and allocation. Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))", as the former is more robust if P's type is changed. Prefer xzalloc to xmalloc + memset 0. Simplify malloc-or-realloc to realloc. Don't worry about xmalloc returning a null pointer. Prefer xstrdup to xmalloc + strcpy. * editfns.c (Fmessage_box): Grow message_text by at least 80 when growing it. * keyboard.c (apply_modifiers_uncached): Prefer local array to alloca of a constant.

All uses removed. * src/alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): * src/lisp.h (USE_LSB_TAG): * src/mem-limits.h (EXCEEDS_LISP_PTR): Use VAL_MAX, not VALBITS, in #if. * src/lisp.h (EMACS_INT_MAX): New macro, useful in #if. (EMACS_UINT): Define unconditionally now. (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG) (BITS_PER_EMACS_INT): New constants, replacing what used to be in config.h, but not useful in #if. (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't define them any more. (VAL_MAX): New macro. (VALMASK): Use it. * src/puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not BITS_PER_EMACS_INT, in #if. * src/s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY) (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed. * src/s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]: * src/s/ms-w32.h (DATA_START): Move here from removed file m/intel386.h. * src/s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this. * src/s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
