Hi all, hi Joseph,
on x86_64-linux I'm seeing many new warnings which didn't exist until a few days ago, see below.
Is that known? Joseph, can it have something to do with your recent libsupc++ changes?
I noticed them too. These warnings say that the unwind-cxx.h
declarations of the exception ABI functions differ in the throw
specification (nothrow) from those implicitly generated by the compiler
(no spec).
However, a svn log shows that neither unwind-cxx.h nor except.c in the
C++ frontend changed this year in a relevant way. So my guess is that
the warning is what changed. Either the warning settings during
compilation, or a new warning was introduced/activated in the compiler
itself.
