From bb677c9581b95720df6b28c375a3278d69e06f44 Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Wed, 10 Nov 2004 15:48:06 +0000 Subject: Update. 2004-11-09 Paolo Bonzini * posix/regexec.c (transit_state): Remove the check for out-of-bounds buffers. (check_matching): Check here for out-of-bounds buffers. (re_search_internal): Store into match_kind a set of bits indicating which incantation of fastmap scanning must be used. Use a switch statement instead of multiple ifs. Exit the final "for (;;)" with goto free_return unless the match succeeded, thus simplifying some conditionals. * posix/regex_internal.c (re_string_reconstruct, re_string_context_at): Add several branch predictions for case-sensitive matching and no transition table being used. 2004-11-10 Ulrich Drepper * posix/tst-waitid.c: Don't use error to print error message, they won't end up in the .out file. * nscd/nscd_getgr_r.c: Likewise. Make map externally visible. * nscd/nscd_gethst_r.c: Likewise. --- posix/regex_internal.c | 34 +++--- posix/regexec.c | 288 ++++++++++++++++++++++++++----------------------- posix/tst-waitid.c | 171 ++++++++++++++--------------- 3 files changed, 250 insertions(+), 243 deletions(-) (limited to 'posix') diff --git a/posix/regex_internal.c b/posix/regex_internal.c index 609719f79c..bb1d73d9a0 100644 --- a/posix/regex_internal.c +++ b/posix/regex_internal.c @@ -576,7 +576,7 @@ re_string_reconstruct (pstr, idx, eflags) int idx, eflags; { int offset = idx - pstr->raw_mbs_idx; - if (offset < 0) + if (BE (offset < 0, 0)) { /* Reset buffer. */ #ifdef RE_ENABLE_I18N @@ -596,10 +596,10 @@ re_string_reconstruct (pstr, idx, eflags) offset = idx; } - if (offset != 0) + if (BE (offset != 0, 1)) { /* Are the characters which are already checked remain? */ - if (offset < pstr->valid_raw_len + if (BE (offset < pstr->valid_raw_len, 1) #ifdef RE_ENABLE_I18N /* Handling this would enlarge the code too much.
