1523 (re_match_2_internal): Remove on_failure_jump_exclusive.
1524 (regex_compile): Turn optimizable P+ loops into PP*, so that the
1525 optimization only need to work for * (ie. can use of_keep_string_jump).
1526 Remove the special case for .*\n since it is now covered by the general
1528 (re_search_2): Don't bother with `room'.
1529 (skip_one_char): New function.
1530 (skip_noops): Simplify since `memory' is not needed any more.

1539 * xfns.c (select_visual): Don't set dpyinfo->n_planes to the
1540 number of bits per RGB because it's everywhere used as the depth

1566 2000-03-15 Stefan Monnier <monnier@cs.yale.edu>
1568 * regex.c (re_match_2): Fix string shortening (to fit `stop') to
1569 make sure POINTER_TO_OFFSET gives the same value before and after
1570 PREFETCH. Use `dfail' to guarantee "atomic" matching.
1571 (PTR_TO_OFFSET): Use POINTER_TO_OFFSET.
1572 (debug): Now only active if > 0 rather than if != 0.
1573 (DEBUG_*): Update for the new meaning of `debug'.
1574 (print_partial_compiled_pattern): Add missing `succeed' case. Use
1575 CHARSET_* macros in the charset(_not) branch. Fix off-by-two bugs

1578 (at_begline_loc_p, at_endline_loc_p): Add prototype.

1614 support functions only if HAVE_X11R6_XIM is defined.
1615 (xim_instantiate_callback): Define only if HAVE_X11R6_XIM.
1617 * s/sol2.h (INHIBIT_X11R6_XIM): Define.

1627 * xterm.h (HAVE_X_I18N) [HAVE_X11R6]: Moved to config.in.
1629 * xterm.c (x_term_init): Add support for X resource `synchronous'.
1630 If set, call XSynchronize.
1632 2000-03-13 Stefan Monnier <monnier@cs.yale.edu>
1634 * regex.c: Declare a new type `re_char' used throughout the code
1635 for the string char type. It's `const unsigned char' to match the
1636 rest of Emacs. Consistently make sure all pointers to strings use
1637 it and make sure all pointers into the pattern use `unsigned
1639 (re_match_2_internal): Use `PREFETCH+STRING_CHAR' instead of
1640 GET_CHAR_AFTER_2. Also merge wordbound and notwordbound to reduce
1643 * charset.h (GET_CHAR_AFTER_2): Remove.
1644 (GET_CHAR_BEFORE_2): Use unsigned chars, like everywhere else.
1646 2000-03-12 Ken Raeburn <raeburn@gnu.org>
1648 * Makefile.in (temacs): Evaluate ALL_LDFLAGS into a temporary
1649 variable before the invocation of YMF_PASS_LDFLAGS, in case both
1650 of them try to use backquotes.
1652 2000-03-12 Dave Love <fx@gnu.org>
1654 * unexelf.c: Restore changes of 1999-10-19.
1655 (unexec): Don't adjust bss for sbss type SHT_PROGBITS; otherwise
1656 fix its type and alignment; copy it from current process.
1658 2000-03-12 Gerd Moellmann <gerd@gnu.org>
1660 * atimer.c (cancel_atimer): Break out of the loop as soon as timer

1684 (IT_set_frame_parameters): Call IT_set_cursor_type if the frame
1685 parameters specify the cursor. Make qreverse a global
1686 variable (renamed to Qreverse).
1688 2000-03-09 Gerd Moellmann <gerd@gnu.org>
1690 * fns.c (Fy_or_n_p): Cancel busy-cursor.
1692 2000-03-08 Stefan Monnier <monnier@cs.yale.edu>
1694 This is a big redesign of failure-stack and register handling, prompted
1695 by bugs revealed when trying to add shy-groups. Overall, what happened
1696 is that loops are now structured a little differently, groups can be
1697 shy and the code is a little simpler.
1699 * regex.h: Update the copyright.
1700 (RE_SHY_GROUPS): New value.
1701 (RE_UNMATCHED_RIGHT_PAREN_ORD): Renumber.
1702 (RE_SYNTAX_EMACS): Add RE_SHY_GROUPS.
1704 * regex.c (enum re_opcode_t): Remove jump_past_alt,
1705 maybe_pop_jump, push_dummy_failure and dumy_failure_jump. Add
1706 on_failure_jump_(exclusive, loop and smart). Also fix the comment
1707 for (start|stop)_memory since they now only take one argument (the
1708 second has becomes unnecessary).
1709 (print_partial_compiled_pattern): Adjust for changes in
1711 (print_compiled_pattern): Use %ld to printf long ints and flush to
1712 make debugging a little easier.
1713 (union fail_stack_elt): Make the integer unsigned.
1714 (struct fail_stack_type): Add a `frame' element.
1715 (INIT_FAIL_STACK): Init `frame' as well.
1716 (POP_PATTERN_OP): New macro for re_compile_fastmap.
1717 (DEBUG_PUSH, DEBUG_POP): Remove.
1718 (NUM_REG_ITEMS): Remove.
1719 (NUM_NONREG_ITEMS): Adjust.
1720 (FAILURE_PAT, FAILURE_STR, NEXT_FAILURE_HANDLE)
1721 (TOP_FAILURE_HANDLE): New macros for the cycle detection.
1722 (ENSURE_FAIL_STACK): New macro for PUSH_FAILURE_(REG|POINT).
1723 (PUSH_FAILURE_REG, POP_FAILURE_REG, CHECK_INFINITE_LOOP): New
1725 (PUSH_FAILURE_POINT): Don't push registers any more. The pattern
1726 address pushed is not the destination of the jump but the source
1728 (NUM_FAILURE_ITEMS): Remove.
1729 (POP_FAILURE_POINT): Adapt to the new stack structure (i.e. pop
1730 registers before the actual failure point). Don't hardcode any
1731 meaning for str==NULL anymore.
1732 (union register_info_type, REG_MATCH_NULL_STRING_P, IS_ACTIVE)
1733 (MATCHED_SOMETHING, EVER_MATCHED_SOMETHING, SET_REGS_MATCHED):
1735 (REG_UNSET_VALUE): Use NULL (why not?).
1736 (compile_range): Remove declaration since it doesn't exist.
1737 (struct compile_stack_elt_t): Remove inner_group_offset.
1738 (old_reg(start|end), reg_info, reg_dummy, reg_info_dummy): Remove.
1739 (regex_grow_registers): Remove dead code.
1740 (FIXUP_ALT_JUMP): New macro.
1741 (regex_compile): Add shy-groups Change loops to use
1742 on_failure_jump_smart&jump instead of
1743 on_failure_jump&maybe_pop_jump. Change + loops to eliminate the
1744 initial (dummy_failure_)jump. Remove c1_base (looks like unused
1745 variable to me). Use `jump' instead of `jump_past_alt' and don't
1746 bother with push_dummy_failure in alternatives since it is now
1747 unnecessary. Use FIXUP_ALT_JUMP. Eliminate a useless `#ifdef
1748 emacs' for (re)allocating the stack.
1749 (re_compile_fastmap): Remove dead variables i and num_regs. Exit
1750 from loop when bufp->can_be_null rather than jumping to `done'.
1751 Avoid jumping backwards so as to ensure termination. Use
1752 PATTERN_STACK_EMPTY and POP_PATTERN_OP. Improved handling of
1753 backreferences. Remove dead code in handling of `anychar'.
1754 (skip_noops, mutually_exclusive_p): New functions taken from the
1755 handling of `maybe_pop_jump' in re_match_2_internal. Slightly
1756 improve mutually_exclusive_p to handle ".+\n".
1757 (lowest_active_reg, highest_active_reg,
1758 NO_(LOWEST|HIGHEST)_ACTIVE_REG) Remove.
1759 (re_match_2_internal): Use %p instead of 0x%x when printf'ing
1760 ptrs. Don't SET_REGS_MATCHED anymore. Remove many dead
1761 variables. Push register (in `start_memory') on the stack rather
1762 than storing it in old_reg(start|end). Remove the cycle detection
1763 from `stop_memory', replaced by the use of on_failure_jump_loop
1764 for greedy loops. Add code for the new on_failure_jump_<foo>.
1765 Remove ad-hoc code in `on_failure_jump' to push more registers in
1766 the case of a loop. Take out code from `maybe_pop_jump' into
1767 separate functions and adapt it to the semantics of
1768 `on_failure_jump_smart'. Remove jump_past_alt, dummy_failure_jump
1769 and push_dummy_failure. Remove dummy_failure handling and
1770 handling of `failures to jump to on_failure_jump' (this last one
1771 was already dead code, it seems).
1772 (group_match_null_string_p, alt_match_null_string_p)
1773 (common_op_match_null_string_p): Remove.
1775 2000-03-08 Dave Love <fx@gnu.org>
1777 * config.in: Don't depend on __STDC__ for volatile.
1778 Add POINTER_TYPE, PTR, PROTOTYPES.
1780 * hftctl.c, strftime.c: Use PROTOTYPES.
1781 * eval.c (find_handler_clause): Likewise.
1783 * mem-limits.h: Use POINTER_TYPE.

1808 (detect_coding_utf_16): New function
1809 (detect_coding_mask): When priorities are specified, skip any
1810 categories that have `nil' coding-system. Fix bug of returning
1811 wrong mask when PRIORITIES is specified and detect_coding_XXX()
1812 returns a mask not set in PRIORITIES.
1813 (detect_eol_type_in_2_octet_form): New function.
1814 (detect_eol): selects detect_eol_type_XXX to call according to

1842 2000-03-06 Gerd Moellmann <gerd@gnu.org>

1845 might become invalid when a GC happens. Instead, access the
1846 process name slot directly.
1848 * xfns.c (x_set_menu_bar_lines_1): Adjust window's orig_top and
1851 * frame.c (set_menu_bar_lines_1): Adjust window's orig_top and
