Constructors

[GideonZ]

As promised, hereby the pull request with the necessary changes to the crt0.s and linker script to support the proper initialization of C++ objects by calling the constructors. A small demo shows that the static objects have been initialized properly.

This is amazing!
I did not expect that a c++ setup would work this flawlessly - actually, I did not expect that it would work at all! 😅

Calling the constructor and destructors "manually" from crt0 (and not using call __libc_init_array) seems to be a nice way to avoid library code being pulled in. There shouldn't be any functional difference, right?

I will have a closer look at your code but I think I am absolutely fine with merging this as-is. 👍

edit

Maybe we should merge #323 first to avoid too much merge conflicts here.

@GideonZ you are OK with the changes?

Absolutely. I saw a few typos in the documentation that you may want to have a look at, but it's just minor. Actually I admire your diligence of updating the documentation with these changes!
