The C++ standard for the F-35 Fighter Jet [video]

TL;DR

- no exceptions

- no recursion

- no malloc()/free() in the inner-loop

That’s hardly 90% of C++.

If you compile with -fno-exceptions you just lost almost all of the STL.

You can compile with exceptions enabled, use the STL, but strictly enforce no allocations after initialization. It depends on how strict is the spec you are trying to hit.

Not my experience. I work with a -fno-exceptions codebase. Still quite a lot of std left. (Exceptions come with a surprisingly hefty binary size cost.)

Not exactly sure what your experience is, but if you work with in an -fno-exceptions codebase then you know that STL containers are not usable in that regime (with the exception of std::tuple it seems, see freestanding comment below). I would argue that the majority of use cases of the STL is for its containers.

So, what exact parts of the STL do you use in your code base? Most be mostly compile time stuff (types, type trait, etc).

You can use std containers in a no-exceptions environment. Just know that if an error occurs the program will terminate.
