What I've been working on for the last month or so.

https://github.com/D-Programming-Language/dmd/pull/5324

For Linux 64 anyway. Anyone who wants to do PRs to extend it to Linux 32, OSX and FreeBSD, feel free! Unfortunately, this is of no help with Win64, which uses its own unique system. DMD for Win32 already can catch C++ exceptions, but Win32 is a dead platform.

This is an enabling technology that will confer on D the ability to catch C++ exceptions, which is key to interaction with native C++ libraries.

Next up: actually catching C++ exceptions!

Thanks to everyone who helped out with this.

Congrats!

What is involved in catching C++ exceptions? Was this the hard part of the whole thing?

So, we have ELF binaries and DWARF exceptions. Are we going to get something related to orcs or goblins next? ;)

Naw, but I am secretly working on the Eye of Sauron.

DMD doesn't catch them yet. But C++ on Linux throws them in Dwarf format, so supporting that is the first step.

I don't know about that, but with better C++ interop, it might be easier to bind to OGRE. (See http://www.ogre3d.org/)

LOL. And wouldn't _that_ show how powerful D is. ;)

Very cool.  Is it conceivable that DMD, GDC, and LDC might one day share common support code in druntime (personality, etc)?  Could be many benefits like a larger test population.

Useless work.
Almost nobody will throw exceptions from C++ code to D code.
Same old same old : Walter could fix regressions, but instead he found a new nice useless toy to play, and after that, it will be a cause of new regressions.

That's why D is always dead in the water.

Probably not the personality routine, though that won't matter.
