For the 64-bit PowerPC SVR4 subtarget, an error occurs in the pass_v8qi
function during instruction selection on one of the GCC ABI compatibility
tests, as follows:

spawn /home/wschmidt/llvm/install/llvm-base/bin/clang -w -DSKIP_DECIMAL_FLOAT
-DSKIP_DECIMAL_FLOAT -c -m64 -o c_compat_x_alt.o
/home/wschmidt/gcc/gcc-mainline-base/gcc/testsuite/gcc.dg/compat//vector-1_x.c

compiler exited with status 1
output is:
