Windows

On Windows, there are two debug information formats in common use: the Microsoft PDB (msvc ABI), used primarily by Microsoft toolchains, and DWARF (gnu ABI), originating from Unix toolchains (GCC, LLVM, etc).

LLDB supports both of these formats, however, being a relatively recent addition, PDB support is still somewhat buggy and you may experience problems with it, up to and including debugger crashes. For this reason, when there is a choice, using -gnu ABI compilation targets is recommended (e.g. x86_64-pc-windows-gnu).

Rust users should also be aware that until version 1.55, PDB support in rustc was lacking (most notably around features related to enums). If you must use the msvc ABI, be sure you have a recent version of the compiler.
