GCC Maintainers:
The following patch fixes issues found with the instruction counts for
the vsx-vector-6.h test. It was found that on a BE system where GCC is
configured with --with-cpu=power6 the expected counts in vsx-vector-6-
be.c do not match. This patch fixes the expected counts when
configuring and building GCC using --with-cpu=power6, --with-cpu=power7
and --with-cpu=power8 on a BE system.
The patch was tested on
powerpc64le-unknown-linux-gnu (Power 8 LE)
powerpc64-unknown-linux-gnu (Power 8 BE) configured for power6
powerpc64-unknown-linux-gnu (Power 8 BE) configured for power7
powerpc64-unknown-linux-gnu (Power 8 BE) configured for power8
Please let me know if the patch looks OK for GCC mainline.
Carl Love

gcc/testsuite/ChangeLog:
2018-05-10 Carl Love <c...@us.ibm.com>
* gcc.target/powerpc/vsx-vector-6-be.c (dg-options): Update to run on
Power 6 only.
(dg-final): Update xvcmpgtdp, xvcmpgedp counts for Power 6.
* gcc.target/powerpc/vsx-vector-6-be.p7.c (dg-final): New test file for
Power 7.
* gcc.target/powerpc/vsx-vector-6-be.p8.c (dg-final): New test file for
Power 8.
