Subject: [PATCH] enable default_cxa_atexit for AIX 6.1 and AIX 7.1
From: David Edelsohn <dje.gcc@gmail.com>
To: GCC Patches <gcc-patches@gcc.gnu.org>
Content-Type: text/plain; charset=UTF-8
X-SW-Source: 2015-10/txt/msg02566.txt.bz2

cxa_atexit functionality for AIX was added to libgcc a while ago.  It
seems stable in all of the testing.  This patch enables it by default.

Bootstrapped on powerpc-ibm-aix7.1.0.0, powerpc-ibm-aix7.1.2.0,
powerpc-ibm-aix7.1.3.0

Thanks, David

* config.gcc (powerpc-ibm-aix[6789])[default_use_cxa_atexit]: Set to yes.
