commit ae5c498d93d049d9574d3f8f18e62cac64cbdf5c
Author: DJ Delorie <dj@delorie.com>
Date: Mon Jul 17 15:50:43 2017 -0400
Extend NSS test suite
* nss/nss_test.h: New.
* nss/nss_test1.h: Rewrite to use test-provided data. Add group
tests. Parameterize to allow multiple instances.
* nss/nss_test2.h: New. Second instance.
* nss/nss_test.ver: New.
* nss/nss_test1.c: Update to use new framework.
* nss/nss_test2.c: New.
* nss/nss_test3.c: New.
* nss/nss_test4.c: New.
* nss/nss_test5.c: New.
* nss/Makefile: Build new tests.
* shlib-versions: Add libnss_test2.
Moved nss/Makefile to separate patch to resolve conflicts.
