Thanks

Thank you thank you thank you thank you.

Supporting struct and class internals would be great, but I guess we'll take this some step at a time...

How about strings?  GDB seems to detect them as "unsigned long long"... Once you get struct internals working, you should probably make dynamic arrays structs, but until then, why not make strings appear as char*?  They should then work with GDB, since DMD puts a null character in them.

If there's anything that GDB doesn't quite support, but DWARF seems to, then let me know... No promises, but I'll poke around GDB and (if sucessful) add stuff to the patch.  It's very possible that there's stuff for dealing with classes and such in DWARF and GDB, but won't currently work with GDB since GDB treats D code like C code.  I can probably fix at least some of that.

You're welcome!

Yes.

The trouble is that strings are arrays. Arrays are a 64 bit type. If dmd puts it out as a struct, then gdb wrongly assumes that it's returned like a struct, instead of in the EDX:EAX register pair. (windbg has the same problem)

The number one thing would be to support the D array type. A DW_TAG_dynamic_array_type would work.

The number two thing would be to support register variables in register pairs. Although you can specify that to codeview, there seems no way to do it in dwarf.
