This is a port of gcc for Unikraft as an external library.

For the time being we only port libbacktrace and libffi libraries as they are needed for the libgo port. You will need newlib for both libraries to build. In addition,

For libffi you will need the pthread_embedded external library too.

For libbacktrace you will need the following external libraries:

• compiler-rt
• libunwind
• libcxx
• libcxxabi

Note that because of a documented bug in libunwind unw_getcontext leads to a page fault, and in turn backtrace_fullwill also lead to one 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 for further information.
