Depending on the architecture, this can impact the debugging experience in different ways. For example, on most 32-bit x86 architectures, you can simply -compile with -fno-omit-frame-pointer for GCC and -fdisable-fp-elim for LLVM. +compile with -fno-omit-frame-pointer for GCC and -disable-fp-elim for LLVM. When GDB creates a backtrace, it can properly unwind the stack, but the stack frames owned by JITed code have ??'s instead of the appropriate symbol name. However, on Linux x86_64 in particular, GDB relies on the DWARF CFA debug
