I didn't stop working on it, but I didn't make real progress anymore
either. The current state of the LLVM code
generator is that everything works on Darwin/x86-64, except for
a) exception handling in general: indeed needs DWARF-EH support in
the RTL,
This is something I would like to work for years on already. So maybe
its now a good opportunity to start with it.
I started a branch for
it:https://svn.freepascal.org/svn/fpc/branches/debug_eh
As a first step, I'll depend on libgcc unwinding, let's see how far
we get.
Using libgcc's foreign exception support works somewhat, but is not
very usable in practice due to the limitation of having only one
exception in flight. I simply started translating all of libgcc's
exception support to Pascal, since it's also licensed under LGPL +
linking exception (I took the one from gcc 4.2.1 for the people who
don't like (L)GPL3).
As you already started working on translating that part of libgcc, would
you please provide what you have so far? :)
Regards,
Sven
