Bug ID: 93965
Summary: Problematic ld_date configure check
Product: gcc
Version: 9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: other
Assignee: unassigned at gcc dot gnu.org
Reporter: marxin at gcc dot gnu.org
Target Milestone: ---
We're trying as SUSE to update binutils in our Factory and I noticed strange
configure detection. We've got the following version of ld:
$ ld -v
GNU ld (GNU Binutils; openSUSE Tumbleweed) 2.34.0.20200216-385
which is then wrongly parsed in gcc/configure.ac:
ld_date=`echo $ld_ver | sed -n
's,^.*\([2-9][0-9][0-9][0-9]\)[-]*\([01][0-9]\)[-]*\([0-3][0-9]\).*$,\1\2\3,p'`
$ echo "GNU ld (GNU Binutils; openSUSE Tumbleweed) 2.34.0.20200216-385" | sed
-n
's,^.*\([2-9][0-9][0-9][0-9]\)[-]*\([01][0-9]\)[-]*\([0-3][0-9]\).*$,\1\2\3,p'
20021638
Obvious fix would be removal of the '[-]*' parts of the regex.
Is there any ld that uses 2020-02-28 datetime format? The code is there for at
least 16 years.
