Make qreverse a global + variable (renamed to Qreverse). + +2000-03-09 Gerd Moellmann + + * fns.c (Fy_or_n_p): Cancel busy-cursor. + +2000-03-08 Stefan Monnier + + This is a big redesign of failure-stack and register handling, prompted + by bugs revealed when trying to add shy-groups. Overall, what happened + is that loops are now structured a little differently, groups can be + shy and the code is a little simpler. + + * regex.h: Update the copyright. + (RE_SHY_GROUPS): New value. + (RE_UNMATCHED_RIGHT_PAREN_ORD): Renumber. + (RE_SYNTAX_EMACS): Add RE_SHY_GROUPS. + + * regex.c (enum re_opcode_t): Remove jump_past_alt, + maybe_pop_jump, push_dummy_failure and dumy_failure_jump. Add + on_failure_jump_(exclusive, loop and smart). Also fix the comment + for (start|stop)_memory since they now only take one argument (the + second has becomes unnecessary). + (print_partial_compiled_pattern): Adjust for changes in + re_opcode_t. + (print_compiled_pattern): Use %ld to printf long ints and flush to + make debugging a little easier. + (union fail_stack_elt): Make the integer unsigned. + (struct fail_stack_type): Add a `frame' element. + (INIT_FAIL_STACK): Init `frame' as well. + (POP_PATTERN_OP): New macro for re_compile_fastmap. + (DEBUG_PUSH, DEBUG_POP): Remove. + (NUM_REG_ITEMS): Remove. + (NUM_NONREG_ITEMS): Adjust. + (FAILURE_PAT, FAILURE_STR, NEXT_FAILURE_HANDLE) + (TOP_FAILURE_HANDLE): New macros for the cycle detection. + (ENSURE_FAIL_STACK): New macro for PUSH_FAILURE_(REG|POINT). + (PUSH_FAILURE_REG, POP_FAILURE_REG, CHECK_INFINITE_LOOP): New + macros. + (PUSH_FAILURE_POINT): Don't push registers any more. The pattern + address pushed is not the destination of the jump but the source + of it instead. + (NUM_FAILURE_ITEMS): Remove. + (POP_FAILURE_POINT): Adapt to the new stack structure (i.e. pop + registers before the actual failure point). Don't hardcode any + meaning for str==NULL anymore. + (union register_info_type, REG_MATCH_NULL_STRING_P, IS_ACTIVE) + (MATCHED_SOMETHING, EVER_MATCHED_SOMETHING, SET_REGS_MATCHED): + Remove. + (REG_UNSET_VALUE): Use NULL (why not?). + (compile_range): Remove declaration since it doesn't exist. + (struct compile_stack_elt_t): Remove inner_group_offset. + (old_reg(start|end), reg_info, reg_dummy, reg_info_dummy): Remove. + (regex_grow_registers): Remove dead code. + (FIXUP_ALT_JUMP): New macro. + (regex_compile): Add shy-groups Change loops to use + on_failure_jump_smart&jump instead of + on_failure_jump&maybe_pop_jump. Change + loops to eliminate the + initial (dummy_failure_)jump. Remove c1_base (looks like unused + variable to me). Use `jump' instead of `jump_past_alt' and don't + bother with push_dummy_failure in alternatives since it is now + unnecessary. Use FIXUP_ALT_JUMP. Eliminate a useless `#ifdef + emacs' for (re)allocating the stack. + (re_compile_fastmap): Remove dead variables i and num_regs. Exit + from loop when bufp->can_be_null rather than jumping to `done'. + Avoid jumping backwards so as to ensure termination. Use + PATTERN_STACK_EMPTY and POP_PATTERN_OP. Improved handling of + backreferences. Remove dead code in handling of `anychar'. + (skip_noops, mutually_exclusive_p): New functions taken from the + handling of `maybe_pop_jump' in re_match_2_internal. Slightly + improve mutually_exclusive_p to handle ".+\n". + (lowest_active_reg, highest_active_reg, + NO_(LOWEST|HIGHEST)_ACTIVE_REG) Remove. + (re_match_2_internal): Use %p instead of 0x%x when printf'ing + ptrs. Don't SET_REGS_MATCHED anymore. Remove many dead + variables. Push register (in `start_memory') on the stack rather + than storing it in old_reg(start|end). Remove the cycle detection + from `stop_memory', replaced by the use of on_failure_jump_loop + for greedy loops. Add code for the new on_failure_jump_. + Remove ad-hoc code in `on_failure_jump' to push more registers in + the case of a loop. Take out code from `maybe_pop_jump' into + separate functions and adapt it to the semantics of + `on_failure_jump_smart'. Remove jump_past_alt, dummy_failure_jump + and push_dummy_failure. Remove dummy_failure handling and + handling of `failures to jump to on_failure_jump' (this last one + was already dead code, it seems). + (group_match_null_string_p, alt_match_null_string_p) + (common_op_match_null_string_p): Remove. + +2000-03-08 Dave Love + + * config.in: Don't depend on __STDC__ for volatile. + Add POINTER_TYPE, PTR, PROTOTYPES. + + * hftctl.c, strftime.c: Use PROTOTYPES. + * eval.c (find_handler_clause): Likewise. + + * mem-limits.h: Use POINTER_TYPE. + + * lisp.h (P_): Define based on PROTOTYPES, not __STDC__. + (memory_warnings): Declare using POINTER_TYPE. + 2000-03-08 Gerd Moellmann + * xfns.c (x_set_cursor_type): If ARG is nil, give frame no cursor. + + * xdisp.c (display_echo_area): Temporarily inhibit garbage + collection. + * xfns.c: Remove obsolete code in #if 0. (Fx_focus_frame): New function.
