------- Comment #38 from howarth at nitro dot med dot uc dot edu 2009-12-19 00:35 -------
I've confirmed that both the WalkerTest failures and the gcj compiler crashes
on java code are eliminated on darwin10 if I duplicate the code for
_Unwind_FindEnclosingFunction() as _darwin10_Unwind_FindEnclosingFunction() and
export that via the versioned libgcc_ext. So the entire problem is that
darwin10's _Unwind_FindEnclosingFunction() is non-functional (and just calls
abort()). Fortunately, since FSF gcc builds on darwin10 without compact unwind
we still have access to a functional _Unwind_Find_FDE(). We just need to find
some approach short of adding a new symbol to libgcc that will provide an
alternate means of accessing the code for _Unwind_FindEnclosingFunction() on
darwin.
