X-Git-Tag: upstream/2.30~19562
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=f0248ca59ce89cd5191553b58ce74863f3af6f24;p=external%2Fglibc.git

* scripts/abilist.awk: If given -v filename_regexp and/or -v

	libname_regexp when parsing names, then produce output only

	stanzas for a final sorting by stanza header at the end.
