Sorry for the slow response, was away last week. On x86 host, I built a compiler

configure --enable-languages=c,c++,lto --target=s390-none-linux-gnu
make all-gcc
make check-gcc RUNTESTFLAGS=tree-ssa.exp=ssa-dom-cse-2.c

and that shows the tests passing. gcc -v shows little further:
Reading specs from ./gcc/specs
COLLECT_GCC=./gcc/xgcc
COLLECT_LTO_WRAPPER=./gcc/lto-wrapper
Target: s390-none-linux-gnu
Configured with: /work/alalaw01/src2/gcc/configure --enable-languages=c,c++,lto 
--target=s390-none-linux-gnu
Thread model: posix
gcc version 6.0.0 20151206 (experimental) (GCC)

I speculate that perhaps the -march=z13 is default for s390 *linux* ???

If you can send me alternative configury, or dumps from your failing compiler 
(dom{2,3}-details, optimized), I can take a look.

Thanks, Alan
