I ported llvm backend and lldb recently. Both tools can basically work.
lldb is able to debug programs in asm style and frame unwinding is OK.
But "frame variable XX" does not work because lldb is not able to determine
the address of
XX from debug info.
I recently did some work with the debug info as generated by llvm, and
there are a lot of bugs. LLVM writes wrong DWARF info. My impression is
that DWARF writer is barely passable with clang-generated code, or maybe
it malfunctions with clang as well. People don't hold debug info to the
same high standard as the code itself.
Here is an example when variable info generated is plain wrong:
