------- Comment #3 from howarth at nitro dot med dot uc dot edu 2010-03-31 14:53 ------- Does this change applied to libmudflap (which we don't build on darwin) provide a template for what we might need to do?

Modified: trunk/config/ChangeLog trunk/config/tls.m4 trunk/libmudflap/ChangeLog trunk/libmudflap/config.h.in trunk/libmudflap/configure trunk/libmudflap/configure.ac trunk/libmudflap/mf-hooks3.c trunk/libmudflap/mf-impl.h trunk/libmudflap/mf-runtime.c I noticed they they are opting out of using __thread in a particular case for emulated TLS. Perhaps this is another instance requiring a similar change. This was proposed in... http://gcc.gnu.org/ml/gcc-patches/2009-01/msg00406.html and discussed in the thread leading up to that post (which terminates the thread). -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43602
