commit 6ec414025531537bf1bb5d1d9ef9c8dcf43b5789
Author: Wainer dos Santos Moschetta <wainersm@linux.vnet.ibm.com>
Date: Tue Feb 21 10:17:32 2017 -0300
powerpc: Add tests for __ppc_set_ppr_* functions.
The sys/platform/ppc.h header defines a class of __ppc_set_ppr functions
used to set the Program Priority Register (PPR) in PowerPC.
This patch implements test cases for these functions.
Tested on ppc64le, ppc64, and ppc.
* sysdeps/powerpc/tst-set_ppr.c: New file.
Implement test cases for __ppc_set_ppr_* functions.
* sysdeps/powerpc/Makefile ($(subdir),misc): Add tst-set_ppr
in the list of tests.

powerpc: Convert tests to the new support test-driver
Change the powerpc tests to use <support/test-driver.c>.
Also replace some of pthread calls to its xpthread equivalent.
Tested on ppc64le.
* sysdeps/powerpc/test-get_hwcap.c: Use <support/test-driver.c>
instead of test-skeleton.c.
(do_test): Replaced pthread_create and pthread_join with
xpthread_create and xpthread_join. Use TEST_VERIFY_EXIT macro.
Removed unneeded status variable.
* sysdeps/powerpc/test-gettimebase.c: Use <support/test-driver.c>
instead of test-skeleton.c.
* sysdeps/powerpc/tst-tlsopt-powerpc.c: Likewise.
