--- Comment #3 from Martin Sebor <msebor at gcc dot gnu.org> ---
On powerpc64le, both 4.9.2 and 5.3.0 emit similar code for the test case as
current trunk.  Since the change referenced in the Description (in r230167) is
a testsuite-only change, is this really a target regression?  It seems that
it's regression in the testsuite, which would presumably make this a lower
priority than some other bugs.

As a data point, though, Clang emits the following with -O2:
