--- 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:
addis 4, 2, b@toc@ha
lwz 5, b@toc@l(4)
rlwimi 5, 3, 0, 8, 11
stw 5, b@toc@l(4)
