--- Comment #15 from Dominique d'Humieres <dominiq at lps dot ens.fr> ---
With the patch in comment 14, I get

        === obj-c++ Summary for unix/-m64 ===

# of expected passes        3073
# of unexpected failures    13
# of expected failures        19
# of unresolved testcases    8
# of unsupported tests        74

        === obj-c++ Summary ===

# of expected passes        6207
# of unexpected failures    24
# of expected failures        21
# of unresolved testcases    16
# of unsupported tests        142

and

        === objc Summary for unix/-m64 ===

# of expected passes        5939
# of unexpected failures    27
# of expected failures        6
# of unresolved testcases    10
# of unsupported tests        91

        === objc Summary ===

# of expected passes        12045
# of unexpected failures    43
# of expected failures        12
# of unresolved testcases    20
# of unsupported tests        176

The additional failures compared to the use of the 10.9 SDK are

FAIL: obj-c++.dg/torture/strings/const-cfstring-1.mm   -O*  -fnext-runtime
(test for excess errors)
FAIL: objc.dg/torture/strings/const-cfstring-1.m   -O*  -fnext-runtime (test
for excess errors)
FAIL: objc.dg/objc-foreach-4.m -fnext-runtime (test for excess errors)
FAIL: objc.dg/objc-foreach-5.m -fnext-runtime (test for excess errors)

Apparently they are related to the fact that NS_BLOCKS_AVAILABLE is no longer
checked.
