I just realized that unikernel apparently already has the symbol file support: https://github.com/unikraft/unikraft/blob/b920d20bcbf62d5bad7ed88407692af1580a2839/plat/kvm/Linker.uk#L60

  • Try it, understanding the structure
  • How many symbols are gone after LTO and DCE? How can we keep some symbols?
  • Integrate with ushell

If we enable CONFIG_OPTIMIZE_SYMFILE=y, then the build system creates build/app-kvm-x86_64.sym using nm command. So basically this is the same as what we are doing now to get symbol information.
