2012-07-27T06:04:35Z!dmantipov@yandex.ru. src/lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for enumeration constants, as PURE and HEAP are too general, and clash with other headers and sources, such as gmalloc.c and the MS-Windows system headers. All users changed.

* alloc.c, editfns.c, marker.c, lisp.h: Revert. Lots of crashes reported by Chong Yidong <cyd@gnu.org>.
2012-07-26Improve GDB symbol export.Paul Eggert

* alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL) (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from emacs.c, as this is a more-suitable home. Had this been done earlier the fix for 1995-05-30T23:07:27Z!kwzh@gnu.org would have avoided some of the problems noted in <http://bugs.gnu.org/1995-05-30T23:07:27Z!kwzh@gnu.org#13> by Eli Zaretskii, as the scope problems would have been more obvious. * emacs.c (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS) (gdb_GCTYPEBITS, gdb_USE_LSB_TAG) (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG): Remove; now done in lisp.h. * lisp.h (PUBLISH_TO_GDB): New macro.

(CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB. * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need not be usable in #if. This simplifies things.

2012-07-19* buffer.h (FOR_EACH_BUFFER): Rename from 'for_each_buffer'.Paul Eggert
(FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from 'for_each_per_buffer_object_at'. All uses changed. It's better to use upper-case for macros that cannot be implemented as functions, to give the reader a clue that they're special.

2012-07-10EMACS_TIME simplification (Bug#11875).Paul Eggert
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.
2012-07-10Optimize pure C strings initialization.Dmitry Antipov
* 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.
2012-07-09Minor improvements to make_formatted_string.Paul Eggert
* 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.
