From: "bonzini at gnu dot org" <sourceware-bugzilla@sources.redhat.com> To: glibc-bugs-regex@sources.redhat.com Subject: [Bug regex/507] New: using a dummy re_node_set causes a mild slowdown in regex Date: Thu, 04 Nov 2004 09:00:00 -0000 [thread overview] Message-ID: <20041104090054.507.bonzini@gnu.org> (raw) Several places use a dummy re_node_set instead of avoiding loops entirely. This has a mild (1%) effect on performance and makes the code less clear IMO, hence the patch at http://sources.redhat.com/ml/libc-alpha/2004-11/msg00017.html which removes this variable. The patch also cleans up sift_states_backward, moving the inner loop out of the function into a new build_sifted_states. -- Summary: using a dummy re_node_set causes a mild slowdown in regex Product: glibc Version: unspecified Status: NEW Severity: normal Priority: P2 Component: regex AssignedTo: bonzini at gnu dot org ReportedBy: bonzini at gnu dot org CC: glibc-bugs-regex at sources dot redhat dot com,glibc- bugs at sources dot redhat dot com OtherBugsDependingO 500 nThis: http://sources.redhat.com/bugzilla/show_bug.cgi?id=507 ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
