This patch improves upon a recently committed patch to add support for
Power9 vector absolute difference unsigned instructions in two ways:
1. The dg-require-effective-target directive is changed in all tests to
allow the test to run even though the tests are not run on a Power9
platform, as long as the associated as tool understands Power9
instructions. A dg-skip-if directive is added to all tests to disable
these tests on aix hosts, because that platform is known to have
incompatibilities for these tests.
2. The body of the vadsdub-2.c test is modified to test different
behavior than is tested by vadsdub-1.c. In the previous commit, these
two tests were identical.
gcc/testsuite/ChangeLog:
2016-06-16 Kelvin Nilsen <kel...@gcc.gnu.org>
* gcc.target/powerpc/vadsdu-0.c: Replace
dg-require-effective-target directive to allow test to run on more
platforms, and add dg-skip-if directive to disable test on aix
platforms because of known incompatibilities.
* gcc.target/powerpc/vadsdu-1.c: Likewise.
* gcc.target/powerpc/vadsdu-2.c: Likewise.
* gcc.target/powerpc/vadsdu-3.c: Likewise.
* gcc.target/powerpc/vadsdu-4.c: Likewise.
* gcc.target/powerpc/vadsdu-5.c: Likewise.
* gcc.target/powerpc/vadsdub-1.c: Likewise.
* gcc.target/powerpc/vadsdub-2.c: Replace
dg-require-effective-target directive to allow test to run on more
platforms, and add dg-skip-if directive to disable test on aix
platforms because of known incompatibilities.
(doAbsoluteDifferenceUnsigned): Replace __builtin_vec_vadub call
with vec_absdb call to differentiate this test from vadsdub-1.c.
* gcc.target/powerpc/vadsduh-1.c: Replace
dg-require-effective-target directive to allow test to run on more
platforms, and add dg-skip-if directive to disable test on aix
platforms because of known incompatibilities.
* gcc.target/powerpc/vadsduh-2.c: Likewise.
* gcc.target/powerpc/vadsduw-1.c: Likewise.
* gcc.target/powerpc/vadsduw-2.c: Likewise.
