Having an OS function to do this is nice but as far as I know it doesn't
port
to ELF (without linking in some elf libs) while the C object ports to OSX.
First, it does cause problems because you will get missing symbols for
_minfo_beg and _minfo_end when it's compiled as a dynamic library, trust
me, I've already done this for Tango. Second, It doesn't have to port to
EFL, it's already platform specific.
In this callback I extract module infos, exception handling tables and
TLS data from the mach_header. This is now where the problem comes. I
need an associative array which maps mach_headers to a struct (or
similar) containing module infos, exception handling tables and TLS
data. But I don't have an associative array that works this earily in
the initialization phase of the runtime.
But it will get called from the thread that runs dlopen.
So how do you add/remove an EH table while another thread is
catching exceptions?
I have no idea from what thread that callback will be called from. I
haven't thought about what should happen.
