8 * regex.c: Declare a new type `re_char' used throughout the code
9 for the string char type. It's `const unsigned char' to match the
10 rest of Emacs. Consistently make sure all pointers to strings use
11 it and make sure all pointers into the pattern use `unsigned
12 char'.
66f0296e 13 (re_match_2_internal): Use `PREFETCH+STRING_CHAR' instead of
34e23e5a
GM
14 GET_CHAR_AFTER_2. Also merge wordbound and notwordbound to reduce
15 code duplication.

49 (Qbar, Qcursor_type, outside_cursor): New variables.
50 (syms_of_msdos): Intern and staticpro them.

67
68 This is a big redesign of failure-stack and register handling, prompted
69 by bugs revealed when trying to add shy-groups. Overall, what happened
70 is that loops are now structured a little differently, groups can be
71 shy and the code is a little simpler.
72
73 * regex.h: Update the copyright.
74 (RE_SHY_GROUPS): New value.
75 (RE_UNMATCHED_RIGHT_PAREN_ORD): Renumber.
76 (RE_SYNTAX_EMACS): Add RE_SHY_GROUPS.
77
80460654
GM
78 * regex.c (enum re_opcode_t): Remove jump_past_alt,
79 maybe_pop_jump, push_dummy_failure and dumy_failure_jump. Add
80 on_failure_jump_(exclusive, loop and smart). Also fix the comment
81 for (start|stop)_memory since they now only take one argument (the
82 second has becomes unnecessary).
83 (print_partial_compiled_pattern): Adjust for changes in
84 re_opcode_t.
85 (print_compiled_pattern): Use %ld to printf long ints and flush to
86 make debugging a little easier.
95cd4c40
SM
87 (union fail_stack_elt): Make the integer unsigned.
88 (struct fail_stack_type): Add a `frame' element.
89 (INIT_FAIL_STACK): Init `frame' as well.
90 (POP_PATTERN_OP): New macro for re_compile_fastmap.
91 (DEBUG_PUSH, DEBUG_POP): Remove.
92 (NUM_REG_ITEMS): Remove.
93 (NUM_NONREG_ITEMS): Adjust.
80460654
GM
94 (FAILURE_PAT, FAILURE_STR, NEXT_FAILURE_HANDLE)
95 (TOP_FAILURE_HANDLE): New macros for the cycle detection.
95cd4c40 96 (ENSURE_FAIL_STACK): New macro for PUSH_FAILURE_(REG|POINT).
80460654
GM
97 (PUSH_FAILURE_REG, POP_FAILURE_REG, CHECK_INFINITE_LOOP): New
98 macros.
99 (PUSH_FAILURE_POINT): Don't push registers any more. The pattern
100 address pushed is not the destination of the jump but the source
101 of it instead.
95cd4c40
SM
102 (NUM_FAILURE_ITEMS): Remove.
103 (POP_FAILURE_POINT): Adapt to the new stack structure (i.e. pop
80460654
GM
104 registers before the actual failure point). Don't hardcode any
105 meaning for str==NULL anymore.
95cd4c40 106 (union register_info_type, REG_MATCH_NULL_STRING_P, IS_ACTIVE)
80460654
GM
107 (MATCHED_SOMETHING, EVER_MATCHED_SOMETHING, SET_REGS_MATCHED):
108 Remove.
95cd4c40
SM
109 (REG_UNSET_VALUE): Use NULL (why not?).
110 (compile_range): Remove declaration since it doesn't exist.
111 (struct compile_stack_elt_t): Remove inner_group_offset.
112 (old_reg(start|end), reg_info, reg_dummy, reg_info_dummy): Remove.
113 (regex_grow_registers): Remove dead code.
114 (FIXUP_ALT_JUMP): New macro.
80460654
GM
115 (regex_compile): Add shy-groups Change loops to use
116 on_failure_jump_smart&jump instead of
117 on_failure_jump&maybe_pop_jump. Change + loops to eliminate the
118 initial (dummy_failure_)jump. Remove c1_base (looks like unused
119 variable to me). Use `jump' instead of `jump_past_alt' and don't
120 bother with push_dummy_failure in alternatives since it is now
121 unnecessary. Use FIXUP_ALT_JUMP. Eliminate a useless `#ifdef
122 emacs' for (re)allocating the stack.
123 (re_compile_fastmap): Remove dead variables i and num_regs. Exit
124 from loop when bufp->can_be_null rather than jumping to `done'.
125 Avoid jumping backwards so as to ensure termination. Use
126 PATTERN_STACK_EMPTY and POP_PATTERN_OP. Improved handling of
127 backreferences. Remove dead code in handling of `anychar'.
95cd4c40 128 (skip_noops, mutually_exclusive_p): New functions taken from the
80460654
GM
129 handling of `maybe_pop_jump' in re_match_2_internal. Slightly
130 improve mutually_exclusive_p to handle ".+\n".
131 (lowest_active_reg, highest_active_reg,
132 NO_(LOWEST|HIGHEST)_ACTIVE_REG) Remove.
133 (re_match_2_internal): Use %p instead of 0x%x when printf'ing
134 ptrs. Don't SET_REGS_MATCHED anymore. Remove many dead
135 variables. Push register (in `start_memory') on the stack rather
136 than storing it in old_reg(start|end). Remove the cycle detection
137 from `stop_memory', replaced by the use of on_failure_jump_loop
138 for greedy loops. Add code for the new on_failure_jump_<foo>.
139 Remove ad-hoc code in `on_failure_jump' to push more registers in
140 the case of a loop. Take out code from `maybe_pop_jump' into
141 separate functions and adapt it to the semantics of
142 `on_failure_jump_smart'. Remove jump_past_alt, dummy_failure_jump
143 and push_dummy_failure. Remove dummy_failure handling and
144 handling of `failures to jump to on_failure_jump' (this last one
145 was already dead code, it seems).
146 (group_match_null_string_p, alt_match_null_string_p)
147 (common_op_match_null_string_p): Remove.

184 categories that have `nil' coding-system. Fix bug of returning
185 wrong mask when PRIORITIES is specified and detect_coding_XXX()
186 returns a mask not set in PRIORITIES.
187 (detect_eol_type_in_2_octet_form): New function.
188 (detect_eol): selects detect_eol_type_XXX to call according to
