I will look into this and see if the instruction counts have changed for some
reason.

I recently committed a patch to fix the counts.
commit 5d336ae49528fde3904c9e5bfc83a450429b2961
Author: Carl Love <cel@us.ibm.com>
Date: Fri Mar 10 18:16:52 2023 -0500
rs6000: Fix test int_128bit-runnable.c instruction counts
The test reports two failures on Power 10LE:
FAIL: .../int_128bit-runnable.c scan-assembler-times \\\\mvdivsq\\\\M 1
FAIL: .../int_128bit-runnable.c scan-assembler-times \\\\mvextsd2q\\\\M 6
The current counts are :
vdivsq 3
vextsd2q 4
....
I tested mainline with the head at commit
commit 90685c365794e9afabc6cdc7eae7892ba5d2be3d (HEAD -> master, origin/trunk,
origin/master, origin/HEAD)
Author: Aldy Hernandez <aldyh@redhat.com>
Date: Mon May 22 20:15:19 2023 +0200
Implement some miscellaneous zero accessors for Value_Range.
...
Test gcc.target/powerpc/int_128bit-runnable.c is currently passing without any
regression failures.
I believe this bugzilla is ready to close.
