Thank you. As you mentioned function f, could you please tell for which
function respected stack is created and what is that function f is
responsible for?

Longjmp.S provides setjmp/longjmp and "call a function f on a new stack"
support for multiple CPU architectures. Switching stacks involves saving, restoring, and
avoiding damage to registers. The file is written in multiple assembly languages.
If you have specific questions, I'm willing to take a shot at answering them.
You'll need to look at instruction set reference documents and compiler ABI
documents to fully understand each implementation.
If you're not experienced with assembly language programming, I'd be tempted to
steer clear. Stipulate that the code works, and move on...
Thanks... Dave
