--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
The test is clearly little-endian only, it fails on powerpc64-linux as well:
FAIL: gcc.dg/torture/pr116037.c -O0 execution test
FAIL: gcc.dg/torture/pr116037.c -O1 execution test
FAIL: gcc.dg/torture/pr116037.c -O2 execution test
FAIL: gcc.dg/torture/pr116037.c -O2 -flto -fno-use-linker-plugin
-flto-partition=none execution test
FAIL: gcc.dg/torture/pr116037.c -O2 -flto -fuse-linker-plugin

FAIL: gcc.dg/torture/pr116037.c -O3 -g execution test
FAIL: gcc.dg/torture/pr116037.c -Os execution test
So, either replace
x &= -((VC) vv)[0];
with
#if __BYTE_ORDER__ == __ORDER_LITTLE_ENDIAN__
x &= -((VC) vv)[0];
#elif __BYTE_ORDER__ == __ORDER_BIG_ENDIAN__
x &= -((VC) vv)[sizeof (__int128) - 1];
#else
x &= -(VC) (vv[0]);
#endif
or so.
