The manual for the compiler I use for the microcontrollers is here:

    https://www.ti.com/lit/ug/spru514z/spru514z.pdf

And here's the relevant excerpt:

"The compiler uses the C++03 version of the C++ standard. See the C++ Standard
 ISO/IEC 14882:2003. The language is also described in Ellis and
Stroustrup's The
 Annotated C++ Reference Manual (ARM), but that is not the standard.
For a description
 of unsupported C++ features, see Section 6.2. • ISO-standard run-time
support: The
 compiler tools come with an extensive run-time library. Library
functions conform to the
 ISO C/C++ library standard unless otherwise stated. The library
includes functions for
 standard input and output, string manipulation, dynamic memory allocation, data
 conversion, timekeeping, trigonometry, and exponential and hyperbolic
functions. Functions
 for signal handling are not included, because these are target-system
specific. For more
 information, see Chapter 8. See Section 6.14 for command line options
to select the C
 or C++ standard your code uses."

In reality though I use C++11 stuff on this compiler all the time, and
I just get a compiler warning saying "Warning: using a C++11 feature".

So this particular compiler is about 15 - 20 years behind. So maybe
when we're using C++38, they'll be catching up with C++20.
