------- Comment #34 from howarth at nitro dot med dot uc dot edu 2009-09-18 19:24 ------- If I understand those messages from llvm-dev properly, on Snow Leopard symbols from libgcc_s are ignored and the unwinder is gotten from libSystem now. So doesn't this mean we are just seeing the incompatibilities (code forking) between the system unwinder in darwin10 and that used in FSF gcc trunk? It seems for darwin10 that we would have to either build against the system libgcc with --with-slib or move the unwinder into a libgcc-ext (as was proposed in PR3988 for providing the emutls symbols). Otherwise the unwinder in FSF and system libgcc_s is ignored in favor of that in libSystem in darwin >= 10.6, if I am reading this correctly.
