The jm-insns.c test was changed. It caused the contents of the LR and CTR registers to change.
Committed fix. commit f1d6dec60148d1ca7dc660f98e39ff31a9bfb5a0 (HEAD -> master, origin/master, origin/HEAD) Author: Carl Love <cel@us.ibm.com> Date: Tue Sep 28 15:49:10 2021 +0000 Fix tests for mfspr Split out the mfspr tests into a separate test using command line option "-M". The value in the LR and CTR registers changed. It appears the changes are due to changes in the test program jm-insns.c. Splinting these instructions out will help to minimize the size of future updates when the test program changes.
