--- Comment #1 from William Cohen <wcohen at redhat dot com> ---
On a fresh ppc64le Fedora 39 install and build of systemtap git checkout
(83ea7cbc0fcfd9caf).  The reproducer runs reasonably fast:

# rpm -q kernel systemtap elfutils binutils binutils-debuginfo
kernel-6.8.4-200.fc39.ppc64le
systemtap-5.1-1.fc39.ppc64le
elfutils-0.191-2.fc39.ppc64le
binutils-2.40-14.fc39.ppc64le
binutils-debuginfo-2.40-14.fc39.ppc64le
# time stap -L 'process("/usr/bin/ld").statement("*@*:*")'|wc
