1Fix test case link failure on PowerPC systems with Altivec
2
3Upstream-Status:backport
4
5On systems where the system compiler supports Altivec by default,
6the libunwind Makefile will attempt to build an extra test case
7ppc64-test-altivec. Unfortunately, the link step will fail since
8the Makefile does not actually link against the libunwind library.
9
10Fixed by adding the appropriate LDADD macro.

4Subject: [PATCH] Link libunwind to libgcc_s rather than libgcc
5
6For some architectures, -lgcc and -lgcc_s are not equivalent. On ARM for
7example, libgcc_s.so.1 contains some symbols needed by libunwind which
8are not present in libgcc.
9
10This causes the following link error when building the X.Org X server
11with libunwind support:
12
13 CCLD Xorg
14 /usr/lib/libunwind.so: undefined reference to `__aeabi_unwind_cpp_pr0'
15 /usr/lib/libunwind.so: undefined reference to `__aeabi_unwind_cpp_pr1'
16
17Linking against libgcc_s explicitly solves this problem.
