--- Comment #2 from Andreas Krebbel <krebbel at gcc dot gnu.org> ---
I can confirm this for GCC 5 branch compiling with -march=z196. It does not
seem to get triggered with older -march levels. It also does work fine with
-mno-lra.
On S/390 we need a memory slot when copying 32 bit entities between FPRs and
GPRs. So from a first glance it appears to be related to the handling of
secondary memory needed in LRA.
