1039 character, convert it to a unibyte character.
1040 (struct glyph_string): Delete member `charset'.
1041 (x_set_mouse_face_gc): Call FACE_FOR_CHAR to get face_id. Handle

1065 (try_window_reusing_current_matrix): Don't call scroll run
1066 function if run's current and desired position are the same;
1067 this prevents cursor flickering.
1069 2000-03-19 Stefan Monnier <monnier@cs.yale.edu>

1078 (re_match_2_internal): Remove on_failure_jump_exclusive.

1094 * xfns.c (select_visual): Don't set dpyinfo->n_planes to the
1095 number of bits per RGB because it's everywhere used as the depth
1098 * term.c (calculate_costs): Remove code dealing with X frames.
1100 2000-03-19 Richard M. Stallman <rms@caffeine.ai.mit.edu>

1121 2000-03-15 Stefan Monnier <monnier@cs.yale.edu>
1123 * regex.c (re_match_2): Fix string shortening (to fit `stop') to
1124 make sure POINTER_TO_OFFSET gives the same value before and after
1125 PREFETCH. Use `dfail' to guarantee "atomic" matching.
1126 (PTR_TO_OFFSET): Use POINTER_TO_OFFSET.
1127 (debug): Now only active if > 0 rather than if != 0.
1128 (DEBUG_*): Update for the new meaning of `debug'.
1129 (print_partial_compiled_pattern): Add missing `succeed' case. Use
1130 CHARSET_* macros in the charset(_not) branch. Fix off-by-two bugs
1131 in `succeed_n', `jump_n' and `set_number_at'.

1133 (at_begline_loc_p, at_endline_loc_p): Add prototype.

1143 (re_compile_fastmap): Ifdef out failure_stack_ptr to shut up gcc.
1144 (re_search_2): Use POS_AS_IN_BUFFER. Simplify `room' computation.
1145 (MATCHING_IN_FIRST_STRING): Remove.

1182 * xterm.h (HAVE_X_I18N) [HAVE_X11R6]: Moved to config.in.

1185 If set, call XSynchronize.
1187 2000-03-13 Stefan Monnier <monnier@cs.yale.edu>
1189 * regex.c: Declare a new type `re_char' used throughout the code
1190 for the string char type. It's `const unsigned char' to match the
1191 rest of Emacs. Consistently make sure all pointers to strings use
1192 it and make sure all pointers into the pattern use `unsigned
1194 (re_match_2_internal): Use `PREFETCH+STRING_CHAR' instead of
1195 GET_CHAR_AFTER_2. Also merge wordbound and notwordbound to reduce
1198 * charset.h (GET_CHAR_AFTER_2): Remove.
1199 (GET_CHAR_BEFORE_2): Use unsigned chars, like everywhere else.
1201 2000-03-12 Ken Raeburn <raeburn@gnu.org>
1203 * Makefile.in (temacs): Evaluate ALL_LDFLAGS into a temporary

1207 2000-03-12 Dave Love <fx@gnu.org>
1209 * unexelf.c: Restore changes of 1999-10-19.
1210 (unexec): Don't adjust bss for sbss type SHT_PROGBITS; otherwise
1211 fix its type and alignment; copy it from current process.
1213 2000-03-12 Gerd Moellmann <gerd@gnu.org>
1215 * atimer.c (cancel_atimer): Break out of the loop as soon as timer

1241 variable (renamed to Qreverse).
1243 2000-03-09 Gerd Moellmann <gerd@gnu.org>
1245 * fns.c (Fy_or_n_p): Cancel busy-cursor.
1247 2000-03-08 Stefan Monnier <monnier@cs.yale.edu>
1249 This is a big redesign of failure-stack and register handling, prompted
1250 by bugs revealed when trying to add shy-groups. Overall, what happened
1251 is that loops are now structured a little differently, groups can be
1252 shy and the code is a little simpler.
1254 * regex.h: Update the copyright.
1255 (RE_SHY_GROUPS): New value.
1256 (RE_UNMATCHED_RIGHT_PAREN_ORD): Renumber.
1257 (RE_SYNTAX_EMACS): Add RE_SHY_GROUPS.
1259 * regex.c (enum re_opcode_t): Remove jump_past_alt,
1260 maybe_pop_jump, push_dummy_failure and dumy_failure_jump. Add
1261 on_failure_jump_(exclusive, loop and smart). Also fix the comment
1262 for (start|stop)_memory since they now only take one argument (the
1263 second has becomes unnecessary).
1264 (print_partial_compiled_pattern): Adjust for changes in
1266 (print_compiled_pattern): Use %ld to printf long ints and flush to
1267 make debugging a little easier.
1268 (union fail_stack_elt): Make the integer unsigned.
1269 (struct fail_stack_type): Add a `frame' element.
1270 (INIT_FAIL_STACK): Init `frame' as well.
1271 (POP_PATTERN_OP): New macro for re_compile_fastmap.
1272 (DEBUG_PUSH, DEBUG_POP): Remove.
1273 (NUM_REG_ITEMS): Remove.
1274 (NUM_NONREG_ITEMS): Adjust.
1275 (FAILURE_PAT, FAILURE_STR, NEXT_FAILURE_HANDLE)
1276 (TOP_FAILURE_HANDLE): New macros for the cycle detection.
1277 (ENSURE_FAIL_STACK): New macro for PUSH_FAILURE_(REG|POINT).
1278 (PUSH_FAILURE_REG, POP_FAILURE_REG, CHECK_INFINITE_LOOP): New
1280 (PUSH_FAILURE_POINT): Don't push registers any more. The pattern
1281 address pushed is not the destination of the jump but the source
1283 (NUM_FAILURE_ITEMS): Remove.
1284 (POP_FAILURE_POINT): Adapt to the new stack structure (i.e. pop
1285 registers before the actual failure point). Don't hardcode any
1286 meaning for str==NULL anymore.
1287 (union register_info_type, REG_MATCH_NULL_STRING_P, IS_ACTIVE)
1288 (MATCHED_SOMETHING, EVER_MATCHED_SOMETHING, SET_REGS_MATCHED):
1290 (REG_UNSET_VALUE): Use NULL (why not?).
1291 (compile_range): Remove declaration since it doesn't exist.
1292 (struct compile_stack_elt_t): Remove inner_group_offset.
1293 (old_reg(start|end), reg_info, reg_dummy, reg_info_dummy): Remove.
1294 (regex_grow_registers): Remove dead code.
1295 (FIXUP_ALT_JUMP): New macro.
1296 (regex_compile): Add shy-groups Change loops to use
1297 on_failure_jump_smart&jump instead of
1298 on_failure_jump&maybe_pop_jump. Change + loops to eliminate the
1299 initial (dummy_failure_)jump. Remove c1_base (looks like unused
1300 variable to me). Use `jump' instead of `jump_past_alt' and don't
1301 bother with push_dummy_failure in alternatives since it is now
1302 unnecessary. Use FIXUP_ALT_JUMP. Eliminate a useless `#ifdef
1303 emacs' for (re)allocating the stack.
1304 (re_compile_fastmap): Remove dead variables i and num_regs. Exit
1305 from loop when bufp->can_be_null rather than jumping to `done'.
1306 Avoid jumping backwards so as to ensure termination. Use
1307 PATTERN_STACK_EMPTY and POP_PATTERN_OP. Improved handling of
1308 backreferences. Remove dead code in handling of `anychar'.
1309 (skip_noops, mutually_exclusive_p): New functions taken from the
1310 handling of `maybe_pop_jump' in re_match_2_internal. Slightly
1311 improve mutually_exclusive_p to handle ".+\n".
1312 (lowest_active_reg, highest_active_reg,
1313 NO_(LOWEST|HIGHEST)_ACTIVE_REG) Remove.
1314 (re_match_2_internal): Use %p instead of 0x%x when printf'ing
1315 ptrs. Don't SET_REGS_MATCHED anymore. Remove many dead
1316 variables. Push register (in `start_memory') on the stack rather
1317 than storing it in old_reg(start|end). Remove the cycle detection
1318 from `stop_memory', replaced by the use of on_failure_jump_loop
1319 for greedy loops. Add code for the new on_failure_jump_<foo>.
1320 Remove ad-hoc code in `on_failure_jump' to push more registers in
1321 the case of a loop. Take out code from `maybe_pop_jump' into
1322 separate functions and adapt it to the semantics of
1323 `on_failure_jump_smart'. Remove jump_past_alt, dummy_failure_jump
1324 and push_dummy_failure. Remove dummy_failure handling and
1325 handling of `failures to jump to on_failure_jump' (this last one
1326 was already dead code, it seems).
1327 (group_match_null_string_p, alt_match_null_string_p)
1328 (common_op_match_null_string_p): Remove.
1330 2000-03-08 Dave Love <fx@gnu.org>
1332 * config.in: Don't depend on __STDC__ for volatile.
1333 Add POINTER_TYPE, PTR, PROTOTYPES.

1364 (detect_coding_mask): When priorities are specified, skip any
1365 categories that have `nil' coding-system. Fix bug of returning
1366 wrong mask when PRIORITIES is specified and detect_coding_XXX()
1367 returns a mask not set in PRIORITIES.
1368 (detect_eol_type_in_2_octet_form): New function.
1369 (detect_eol): selects detect_eol_type_XXX to call according to

1397 2000-03-06 Gerd Moellmann <gerd@gnu.org>
1399 * process.c (send_process): Remove local variable `procname' that
1400 might become invalid when a GC happens. Instead, access the
1401 process name slot directly.
1403 * xfns.c (x_set_menu_bar_lines_1): Adjust window's orig_top and
1406 * frame.c (set_menu_bar_lines_1): Adjust window's orig_top and

1460 structure. Copy colormap if resource `privateColormap' is

1465 * xterm.h (struct x_display_info): Add Colormap member `cmap'.
