Ah, that was a while ago, some things have changed :) Since about seven years ago you can configure GDB with --enable-targets=all (or some subset that you're interested in). It's not the default, it takes longer to build, but if you do build like that it should work. > I know about the register numbering stuff and I would love to see > support for the "$qXfer:features:" added to LLDB.

I have to admit that I've not done any work on GDB at the register level and my knowledge of DWARF is such that I know what it is and what it's for but that's all, so I am guessing here. > So please do submit patches that implement this and we will be happy > to approve them. I've worked on GDB, so any code I write is likely tainted from a licensing standpoint. I can make suggestions though. I know that the different licenses block a lot of cooperation between the LLDB and GDB communities, but for things like the gdbserver protocol we could perhaps cooperate through the protocol documentation in gdb/doc/gdb.texinfo. That's licensed under GNU FDL, not GPLv3.
