Hi all,
As reported (https://gcc.gnu.org/ml/gcc-patches/2016-04/msg00094.html)
these two tests now fail to perform shrinkwrapping after a regalloc change,
but at least on arm the resulting code is not worse (not clear if better
either).
They have also been reported to fail on powerpc
One of the proposed solutions for now is to XFAIL them on arm and powerpc, which
is what this patch does.
Is this ok for GCC 6? Or would you like to remove arm and powerpc from the
tested
targets for this altogether?
Thanks,
Kyrill
P.S. I've filed PR rtl-optimization/70681 for this.
