Hi, Some testcases to exercise the vec_splat() built-in. Tested successfully on assorted powerpc Linux systems, in conjunction with the vec-splat() folding patch, which is being posted separately. In building and updating these tests I consciously violated the 80 char per line rule, as I was doing experimentation with the assorted values and making lots of local updates. I've left them as-is just because, but can update that if so desired. OK for trunk? Thanks, -Will [testsuite] 2018-08-07 Will Schmidt <will_schm...@vnet.ibm.com> * gcc.target/powerpc/fold-vec-splat-char.c: New. * gcc.target/powerpc/fold-vec-splat-floatdouble.c: New. * gcc.target/powerpc/fold-vec-splat-int.c: New. * gcc.target/powerpc/fold-vec-splat-longlong.c: New. * gcc.target/powerpc/fold-vec-splat-pixel.c: New. * gcc.target/powerpc/fold-vec-splat-short.c: New.
