Does this mean that the { target c++98 } lines are acceptable in C++11,
while the { xfail c++11 } lines are still errors in C++11, but aren't
detected?  (Daft question really, but wanted to check.)

The reason for asking is that the line:

    g<(void (A::*)()) &B::f>(); // { dg-error "" } 

also fails for C++11 on targets that define TARGET_PTRMEMFUNC_VBIT_LOCATION
to ptrmemfunc_vbit_in_delta.  Is that expected, and if so, is the patch
below OK?  Or should I try to look at it a bit further first?

(This is the only failing C++ test on mips64-linux-gnu.)

Thanks,
Richard


gcc/testsuite/
	* g++.old-deja/g++.pt/ptrmem6.C: xfail a test for ARM and MIPS
	in C++11 mode.

Right.

I'm not sure why that would be, but the patch is OK.  I wouldn't worry 
about trying to get this line right until we fix the other xfails.
