     This is the port of gcc for Unikraft as external library.
     
    +For the time being only libbacktrace and libffi libraries are ported 
because they are 
    +needed for the libgo port. You will need newlib for both libraries. 
    +
    +For libffi you will need pthread\_embedded external library too.
    +
    +Also for libbacktrace you will need the below external libraries:
    ++ compiler-rt 
    ++ libunwind
    ++ libcxx
    ++ libcxxabi
    +
    +Moreover because of a bug in libunwind: `unw_getcontext` leads to page 
fault, 
    +`backtrace_full` function will also lead to page fault, as it uses 
`_Unwind_Backtrace`
    +which calls `unw_getcontext`.
    +
     Please refer to the `README.md` as well as the documentation in the `doc/`
     subdirectory of the main unikraft repository.
