[BZ #1302]
Change bitset word type from unsigned int to unsigned long int,
as this has better performance on typical 64-bit hosts. Change
bitset type name to bitset_t.
* posix/regcomp.c (build_equiv_class, build_charclass):
(build_range_exp, build_collating_symbol):
Prefer bitset_t to re_bitset_ptr_t in prototypes, when the actual
argument is a bitset. This is merely a style issue, but it makes
it clearer that an entire array is expected.

Prefer sizeof (bitset_t) to multiplying it out ourselves.
(bitset_not_merge): Remove; unused.
(bitset_contain): Return bool, not unsigned int with one bit on.

* posix/regexec.c (build_trtable): Don't assume bitset_t has no
stricter alignment than re_node_set; do this by defining a new
internal type struct dests_alloc and using it to allocate memory.

* include/features.h (_POSIX_SOURCE, _POSIX_C_SOURCE): Define
if _XOPEN_SOURCE >= 500 even if __STRICT_ANSI__ is defined.
2005-02-16 Roland McGrath <roland@redhat.com>
Update.
2005-01-27 Paolo Bonzini <bonzini@gnu.org>
[BZ #558]
* posix/regcomp.c (calc_inveclosure): Return reg_errcode_t.
Initialize the node sets in dfa->inveclosures.
(analyze): Initialize inveclosures only if it is needed.
Check errors from calc_inveclosure.
* posix/regex_internal.c (re_dfa_add_node): Do not initialize
the inveclosure node set.
* posix/regexec.c (re_search_internal): If nmatch includes unused
subexpressions, reset them to { rm_so: -1, rm_eo: -1 } here.
* posix/regcomp.c (parse_bracket_exp) [!RE_ENABLE_I18N]:
Do build a SIMPLE_BRACKET token.
* posix/regexec.c (transit_state_mb): Do not examine nodes
where ACCEPT_MB is not set.
2005-01-27 Jakub Jelinek <jakub@redhat.com>
* stdlib/tst-fmtmsg.c: Include stdlib.h.
* stdio-common/tst-fmemopen2.c: Include string.h.
* posix/execvp.c: Include stdbool.h.
Update.
2004-12-13 Paolo Bonzini <bonzini@gnu.org>
Separate parsing and creation of the NFA. Avoided recursion on
the (very unbalanced) parse tree.
[BZ #611]
* posix/regcomp.c (struct subexp_optimize, analyze_tree, calc_epsdest,
re_dfa_add_tree_node, mark_opt_subexp_iter): Removed.
(optimize_subexps, duplicate_tree, calc_first, calc_next,
mark_opt_subexp): Rewritten.
(preorder, postorder, lower_subexps, lower_subexp, link_nfa_nodes,
create_token_tree, free_tree, free_token): New.
(analyze): Accept a regex_t *. Invoke the passes via the preorder and
postorder generic visitors. Do not initialize the fields in the
re_dfa_t that represent the transitions.
(free_dfa_content): Use free_token.
(re_compile_internal): Analyze before UTF-8 optimizations. Do not
include optimization of subexpressions.
(create_initial_state): Fetch the DFA node index from the first node's
bin_tree_t *.
(optimize_utf8): Abort on unexpected nodes, including OP_DUP_QUESTION.
Return on COMPLEX_BRACKET.
(duplicate_node_closure): Fix comment.
(duplicate_node): Do not initialize the fields in the
re_dfa_t that represent the transitions.
(calc_eclosure, calc_inveclosure): Do not handle OP_DELETED_SUBEXP.
(create_tree): Remove final argument. All callers adjusted. Rewritten
to use create_token_tree.
(parse_reg_exp, parse_branch, parse_expression, parse_bracket_exp,
build_charclass_op): Use create_tree or create_token_tree instead
of re_dfa_add_tree_node.
(parse_dup_op): Likewise. Also free the tree using free_tree for
"<re>{0}", and lower OP_DUP_QUESTION to OP_ALT: "a?" is equivalent
to "a|". Adjust invocation of mark_opt_subexp.
(parse_sub_exp): Create a single SUBEXP node.
* posix/regex_internal.c (re_dfa_add_node): Remove last parameter,
always perform as if it was 1. Do not initialize OPT_SUBEXP and
DUPLICATED, and initialize the DFA fields representing the transitions.
* posix/regex_internal.h (re_dfa_add_node): Adjust prototype.
(re_token_type_t): Move OP_DUP_PLUS and OP_DUP_QUESTION to the tokens
section. Add a tree-only code SUBEXP. Remove OP_DELETED_SUBEXP.
(bin_tree_t): Include a full re_token_t for TOKEN. Turn FIRST and
NEXT into pointers to trees. Remove ECLOSURE.

[BZ #605]
* posix/regcomp.c (parse_bracket_exp): Do not modify DFA nodes
that were already created.
* posix/regex_internal.c (re_dfa_add_node): Set accept_mb field
in the token if needed.
(create_ci_newstate, create_cd_newstate): Set accept_mb field
from the tokens' field.
* posix/regex_internal.h (re_token_t): Add accept_mb field.
(ACCEPT_MB_NODE): Removed.
* posix/regexec.c (proceed_next_node, transit_states_mb,
build_sifted_states, check_arrival_add_next_nodes): Use
accept_mb instead of ACCEPT_MB_NODE.
2005-01-22 Ulrich Drepper <drepper@redhat.com>
* posix/Makefile: Use CFLAGS-*.os instead of CFLAGS-*.c for frame
pointer option.
* stdlib/Makefile (CFLAGS-system.os): Use this instead of
CFLAGS-system.c for frame pointer option.
2005-01-20 Ulrich Drepper <drepper@redhat.com>
* posix/execl.c: Do not allocate potentially large buffers on the
stack.
* posix/execle.c: Likewise.
* posix/execlp.c: Likewise.
* posix/execlp.c: Likewise.
(script_execute): Removed.
(allocate_scripts_argv): New function. Called at most once to
allocate memory, not every time a script is run. Adjust caller.
* sysdeps/generic/wordexp.c (exec_comm): Add a few
TEMP_FAILURE_RETRY. Reorganize code to avoid multiple calls to
exec_comm_child.
(exec_comm_child): Can now be inlined.
* posix/Makefile: Add -fomit-frame-pointer for a few more files.
* stdlib/Makefile: Likewise.
2005-01-06 Ulrich Drepper <drepper@redhat.com>
* misc/sys/cdefs.h: Define __wur.
* libio/stdio.h: Use __wur for a number of interfaces.
* posix/unistd.h: Likewise.
* posix/regex_internal.c (free_state): Free word_trtable.
2004-04-27 Paolo Bonzini <bonzini@gnu.org>
* posix/regex_internal.h (struct re_dfastate_t): Make
word_trtable a pointer to the 512-item transition table.
* posix/regexec.c (build_trtable): Fill in either state->trtable
or state->word_trtable. Return a boolean indicating success.
(transit_state): Expect state->trtable to be a 256-item
transition table. Reorganize code to have less tests in
the common case, and to save an indentation level.
