--- Comment #3 from Richard Biener <rguenth at gcc dot gnu.org> ---
Doesn't reproduce with a cross. I've configured with just
--target=s390x-suse-linux thus end up with
> ./xgcc -B. -S des.i -g -O3 -std=c99 -fPIC -pthread -v
Reading specs from ./specs

Configured with: /space/rguenther/src/svn/gcc-6-branch/configure

Thread model: posix

COLLECT_GCC_OPTIONS='-B' '.' '-S' '-g' '-O3' '-std=c99' '-fPIC' '-pthread' '-v'

./cc1 -fpreprocessed des.i -quiet -dumpbase des.i -m64 -mzarch -march=z900
-auxbase des -g -O3 -std=c99 -version -fPIC -o des.s
not sure if -march is the one you see this with.
Ah, using -march=z10 is required to reproduce it and it iterates forever in
VRP.
Investiating.
