All versions of LLDB support all file formats which is currently: ELF, mach-o and COFF. > 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? I would think that the GDB JIT support should work no matter which platform. The code is in a generic plug-in that uses the internal abstracted interface to object files (ELF, mach-o and COFF all look the same to the plug-in). It really comes down to making sure the symbol names are the same between all JIT'ed binaries for the different OSs. Let me know if you have any questions.
