From 81043d1ad854ddd57fc4a7f398cbac5c7740ed09 Mon Sep 17 00:00:00 2001 From: Roland McGrath Date: Thu, 16 Jan 2003 11:28:59 +0000 Subject: 2003-01-16 Roland McGrath Tweak merged .abilist file format to merge duplicate symbols in different sets into multi-version stanzas with new "| SET regexp..." header continuation lines. * scripts/merge-abilist.awk: Rewritten for new format. * scripts/extract-abilist.awk: Likewise. --- scripts/extract-abilist.awk | 87 ++++++++++++++++---- scripts/merge-abilist.awk | 194 +++++++++++++++++++------------------------- 2 files changed, 153 insertions(+), 128 deletions(-) (limited to 'scripts') diff --git a/scripts/extract-abilist.awk b/scripts/extract-abilist.awk index c5b76e1309..e4f466e6a9 100644 --- a/scripts/extract-abilist.awk +++ b/scripts/extract-abilist.awk @@ -2,43 +2,94 @@ # This must be passed run with awk -v config=TUPLE to specify the configuration # tuple we will match.
