When run on powerpc-linux, test obj-c++.dg/encode-3.mm fails with an unexpected
warning:

elm3b11% /opt/gcc-nightly/trunk-20060420/bin/g++ -c encode-3.mm
encode-3.mm: In function ‘int main()’:
encode-3.mm:18: warning: deprecated conversion from string constant to ‘char*’'

Test results for lots of other targets show the test failing.

This testcase has execution failure on mainline for i686 and x86_64:
http://gcc.gnu.org/ml/gcc-testresults/2008-02/msg00466.html
http://gcc.gnu.org/ml/gcc-testresults/2008-02/msg00441.html

On 4.2.x, it passes on both systems:
http://gcc.gnu.org/ml/gcc-testresults/2008-02/msg00468.html
http://gcc.gnu.org/ml/gcc-testresults/2008-02/msg00366.html

on 4.1.x, it passes on i686 but fails on x86_64:
http://gcc.gnu.org/ml/gcc-testresults/2008-02/msg00365.html
http://gcc.gnu.org/ml/gcc-testresults/2008-02/msg00469.html

Between 4.1 and 4.2, there are some changes to the testcase itself that look
like support for lp64 systems.  I believe that explains the failure on 4.1 on
x86_64.  I believe if I backport that testsuite change to 4.1, the testcase
might pass.

However it fails everywhere on mainline, so that is a regression.

If I backport this patch to 4.1:

http://gcc.gnu.org/ml/gcc-patches/2006-09/msg01001.html

the testcase compiles with gcc-4.1 and executes on x86_64.

[Bug objc++/27232] encode-3.mm fails with "deprecated conversion" warning

[ghazi at gcc dot gnu dot org]

------- Comment #6 from ghazi at gcc dot gnu dot org  2008-02-11 04:56 -------
The original issue reported in here was a "deprecated conversion" warning in
gcc-4.2.  Later on to confuse things an execution failure was noted on mainline
and an LP64 problem was reported on gcc-4.1 in the same testcase.

The "deprecated conversion" warning was fixed long ago on 4.2 by the same patch
that fixed LP64.  There was a constification snuck in there that fixed it.  See
the patch in comment#4.

By backporting that change to 4.1, the testcase passes there on LP64 targets
also.  The "dedeprecated conversion" warning was never an issue in 4.1.

Lastly the execution failure remains on mainline, but that bug is a separate
issue and is already noted in PR32052.

Since the execution failure is covered elsewhere, and the other problems are
fixed, I'm closing this one.
