Subject: [PATCH] recordmcount.pl: look for jgnop instruction as well as bcrl on s390
Date: Fri, 10 Dec 2021 10:38:27 +0100 [thread overview]
Message-ID: <20211210093827.1623286-1-jmarchan@redhat.com> (raw)
On s390, recordmcount.pl is looking for "bcrl 0,<xxx>" instructions in
the objdump -d outpout. However since binutils 2.37, objdump -d
display "jgnop <xxx>" for the same instruction. Update the
mcount_regex so that it accepts both.
