[lldb-dev] GDB JIT interface on LLDB for Windows

[Yury Delendik via lldb-dev]

I'm trying to locate more information about the subject. I'm working
on enabling debugging for wasmtime [1]. The wasmtime is a runtime for
WebAssembly code -- a JIT, for purpose of this discussion. Currently,
I'm successfully generate ELF images to be registered using the JIT
interface [2]. It works well on Linux [3] and Mac OS, and now there is
a need to extend it to Windows.

It will be less work for me (and other JIT vendors) if LLDB on Windows
could support ELF/DWARF format. Is or can it be the case? If not, what
will be a preferable format for Windows object file image to be used
in JIT interface, and will it work via __jit_debug_register_code?

Thank you,
Yury
