[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.
(re_compile_fastmap_iter, init_dfa, init_word_char, optimize_subexps,
lower_subexp): Adjust for new bitset_t definition.
(lower_subexp, parse_bracket_exp, built_charclass_op): Likewise.

All uses changed.
(BITSET_WORDS): Renamed from BITSET_UINTS. All uses changed.
(bitset_word_t): New type, replacing 'unsigned int' for bitset uses.
All uses changed.
(BITSET_WORD_MAX): New macro.
(bitset_set, bitset_clear, bitset_contain, bitset_empty,
(bitset_set_all, bitset_copy): Adjust for bitset_t change.
(bitset_empty, bitset_copy):
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.
All callers changed.
* 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.
mbrtowc for very simple UTF-8 case.
2005-09-01 Paul Eggert <eggert@cs.ucla.edu>

* posix/regexec.c (re_search_internal): Simplify update of
rm_so and rm_eo by replacing "if (A == B) A += C - B;"
with the equivalent of "if (A == B) A = C;".
2005-09-06 Ulrich Drepper <drepper@redhat.com>
* posix/regcomp.c (re_compile_internal): Change third parameter type
to size_t.
(init_dfa): Likewise. Make sure that arithmetic on pat_len doesn't
overflow.
* posix/regex_internal.h (struct re_dfa_t): Change type of nodes_alloc
and nodes_len to size_t.
* posix/regex_internal.c (re_dfa_add_node): Use size_t as type for
new_nodes_alloc. Check for overflow.
2005-08-31 Paul Eggert <eggert@cs.ucla.edu>

(optimize_subexps, lower_subexp):
Don't assume 1<<31 has defined behavior on hosts with 32-bit int,
since the signed shift might overflow. Use 1u<<31 instead.

Likewise.
* posix/regexec.c (check_dst_limits_calc_pos_1): Likewise.

* posix/regexec.c (check_dst_limits_calc_pos_1):
(check_subexp_matching_top): Likewise.
* posix/regcomp.c (init_dfa): Make table_size unsigned, so that we
don't have to worry about portability issues when shifting it left.
Remove no-longer-needed test for table_size > 0.
* posix/regcomp.c (parse_sub_exp): Do not shift more bits than there
are in a word, as the resulting behavior is undefined.
* posix/regexec.c (check_dst_limits_calc_pos_1): Likewise;
in one case, a <= should have been an <, and in another case the
whole test was missing.
* posix/regex_internal.h (BYTE_BITS): Remove. All uses changed to
the standard name CHAR_BIT.
next_last_offset.
(struct re_dfa_t): Remove unused member states_alloc.
* posix/regcomp.c (init_dfa): Don't initialize unused members.

* posix/regexec.c (set_regs): Don't alloca with an unbounded size.
alloca modernization/simplification for regex.
* posix/regex.c: Remove portability cruft for alloca. This no longer
needs to be at the start of the file, and can be moved into
regex_internal.h and simplified.
* posix/regex_internal.h: Include <alloca.h>.
(__libc_use_alloca) [!defined _LIBC]: New macro.
* posix/regexec.c (build_trtable): Remove "#ifdef _LIBC",

as per POSIX.
* posix/regex.h (regerror): Likewise.

Similarly for regcomp and regexec. Also, first 2 args of regexec
and 2nd arg of regerror are const.
* posix/regex.c: Do not include <sys/types.h>, as POSIX no longer
requires this. (The code never needed it.)
2005-08-20 Paul Eggert <eggert@cs.ucla.edu>
* posix/regexec.c (sift_states_bkref): re_node_set_insert returns
int, not reg_errcode_t.
* posix/regex_internal.c (calc_state_hash): Put 'inline' before type,
since some broken compilers warn about it otherwise.
* posix/regcomp.c (create_initial_state): Remove duplicate decl.
2005-08-20 Paul Eggert <eggert@cs.ucla.edu>

2005-08-19 Paul Eggert <eggert@cs.ucla.edu>
* posix/regcomp.c (duplicate_node): Return new index, not an error
code, and let the caller return REG_ESPACE if out of space. This
removes an uninitialied-variable warning with GCC 4.0.1, and also
avoids taking the address of a local variable. All callers
changed.
2005-09-06 Ulrich Drepper <drepper@redhat.com>
* include/time.h (__strptime_internal): Rename parameter to avoid
bogus compiler warning.
2005-08-19 Jim Meyering <jim@meyering.net>

re_string_skip_chars just because idx points into a middle of
valid UTF-8 character. Instead, set the wcs bytes which correspond
to the partial character bytes to WEOF.
* posix/regexec.c (re_search_internal): Allocate input.bufs_len + 1
instead of dfa->nodes_len + 1 state_log entries initially.
* posix/bug-regex20.c (main): Uncomment backwards case insensitive
tests.
2003-11-24 Jakub Jelinek <jakub@redhat.com>
* posix/regex_internal.h (re_token_t): Add word_char bit. Add
comment.
(re_dfa_t): Add sb_char field.
(bitset_mask): New function.
* posix/regcomp.c (free_dfa_content): Free sb_char.
(init_dfa): Don't initialize word_char unnecessarily.
Initialize sb_char.
(duplicate_node): Don't duplicate !word_char CHARACTERs with
NEXT_WORD_CONSTRAINT constraint or word_char CHARACTERs with
NEXT_NOTWORD_CONSTRAINT. Return -1 in *new_idx instead.
(duplicate_node_closure): Handle clone_dest == -1 from
duplicate_node.
(peek_token): Initialize word_char bit.
(parse_expression, parse_dup_op): Add comments.
(parse_bracket_exp): Don't set bitmask bits for multi-byte char
starting bytes here at the beginning. Mask off the bits right
before creating SIMPLE_BRACKET.
(build_charclass_op): Likewise.
* posix/regexec.c (group_nodes_into_DFAstates) <case OP_PERIOD>: Only
set accept bits for single-byte characters.
(group_nodes_into_DFAstates): Don't rely on characters 0 .. 127
being single byte encoded and the rest multi-byte.
* posix/bug-regex19.c (tests): Add new tests.
(do_mb_tests): Initialize t to *test.
(main): Fail even on do_mb_tests errors.
2003-11-21 Ulrich Drepper <drepper@redhat.com>
* posix/regcomp.c (fetch_token): Change interface to match
peek_token. This avoid some copying and reduces code size.
2003-11-19 Jakub Jelinek <jakub@redhat.com>
* posix/regexec.c (extend_buffers): Don't allocate
twice as big state_log as needed. Don't modify pstr->valid_len
for mb_cur_max == 1 !icase !trans.
* posix/regcomp.c (free_bin_tree): Removed.
(create_tree): Add dfa argument. Don't call re_malloc for
each tree, instead allocate from str_tree_storage.
(re_dfa_add_tree_node): New function.
(free_dfa_content): Handle freeing if dfa->nodes == NULL
or dfa->state_table == NULL.
(re_compile_internal): Call free_dfa_content if init_dfa
fails. Call free_workarea_compile, re_string_destruct
and free_dfa_content for most of the other failure paths.
(init_dfa): Initialize str_tree_storage_idx.
Don't clear any fields on allocation failure.
(free_workarea_compile): Free str_tree_storage chunks
instead of free_bin_tree (dfa->str_tree).
(parse): Call re_dfa_add_tree_node instead of re_dfa_add_node
followed by create_tree. Add dfa argument to remaining
create_tree calls. Remove new_idx variable. Remove calls
to free_bin_tree.
(parse_reg_exp, parse_branch, parse_expression, parse_sub_exp,
parse_dup_op, parse_bracket_exp, build_charclass_op): Likewise.
(duplicate_tree): Remove calls to free_bin_tree, add dfa
argument to create_tree.
* posix/regex_internal.h (BIN_TREE_STORAGE_SIZE): Define.
(bin_tree_storage_t): New type.
(re_dfa_t): Add str_tree_storage and str_tree_storage_idx
fields.
* posix/Makefile (tests): Add bug-regex21.
(generated): Add bug-regex21-mem, bug-regex21.mtrace,
tst-rxspencer-mem and tst-rxspencer.mtrace.
(tests): Depend on $(objpfx)bug-regex21-mem
and $(objpfx)tst-rxspencer-mem.
(bug-regex21-ENV, tst-rxspencer-ENV): Set.
($(objpfx)bug-regex21-mem, $(objpfx)tst-rxspencer-mem): New.
* posix/tst-rxspencer.c (main): Add call to mtrace.
Free line at the end.
* posix/bug-regex21.c: New test.
* posix/regexec.c (get_subexp): After calling get_subexp_sub
* posix/regex_internal.h (re_token_type_t): Remove unused ALT,
END_OF_RE_TOKEN_T and SUBEXP. Reorder values. Add OP_UTF8_PERIOD
and EPSILON_BIT.
(IS_EPSILON_NODE): Just test if EPSILON_BIT is set.
(ACCEPT_MB_NODE): Return 1 for OP_UTF8_PERIOD as well.
* posix/regex_internal.c (create_ci_newstate, create_cd_newstate):
Handle OP_UTF8_PERIOD.
(re_string_reconstruct): Set valid_len for single byte char searching
with no translation and case sensitivity.
* posix/regcomp.c (re_compile_fastmap_iter, calc_first): Handle
OP_UTF8_PERIOD.
(re_compile_internal): Don't call optimize_utf8 if preg->translate
!= NULL.
(optimize_utf8): Remove BACK_SLASH case.
Transform OP_PERIOD into OP_UTF8_PERIOD if the searching can be
optimized.
(parse_bracket_exp): Don't create SIMPLE_BRACKET if it doesn't have
any bits set and COMPLEX_BRACKET is used.
* posix/regexec.c (transit_state_mb): Fix comment typo.
(group_nodes_into_DFAstates, check_node_accept): Handle
OP_UTF8_PERIOD.
(check_node_accept_bytes): Likewise. Reorder slightly so that
re_string_char_size_at and re_string_elem_size_at are called
only when needed.
* posix/bug-regex20.c (BRE, ERE): Define.
(tests): Use them to make lines shorter. Expect . to be
optimized. Add lots of new tests.
(main): Run (ATM just case sensitive) test with backwards searching
as well.
