Snapdragon Flight Hexagon-side c++11 support?

PX4 Autopilot

Why is Hexagon-side px4 file not compiled with c++11 standard? Are there quirks to this standard or inefficiencies introduced? Context: I would like to use some of the algorithm and functional functions available in c++11 but not prior standards.

Edit: It is in fact compiled with std=gnu++11 standard, but std::any_of() is not a function. Also, QURT OS is not GNU, so why is gnu++11 standard used? Now I’m confused

It’s cmake determining gnu++11. I think that’s because Hexagon is presenting itself as clang, but I haven’t personally used it.
