It however does not support vector __int128_t which is what we're testing here. Peter
[PATCH rs6000] Fix for builtins-4-int128-runnable.c
GCC maintainers: The following patch contains fixes an issue with the 128-bit test on Power 7. Power 7 does not support int128 so the test must be restricted to run on Power 8 and later. The change was tested by hand on a Power 8 machine with the command: make -k check-gcc RUNTESTFLAGS="--target_board=unix'{-mcpu=power7}' powerpc.exp=builtins-4-int128-runnable.c" to verify the test passes cleanly with the change in the dg directives. Please let me know if the patch is OK for trunk. Thanks. Carl Love 2018-02-14 Carl Love * gcc.target/powerpc/builtins-4-int128-runnable.c (dg-require-effective-target): Change vsx_hw to p8vector_hw.
