crafcat7 opened a new pull request, #14537:
URL: https://github.com/apache/nuttx/pull/14537
## Summary
**Why is this change necessary?**
On some compiler platforms, although it is a standard after C11, it does
not provide an ATOMIC toolchain implementation, so we can use this macro to
determine whether it supports toolchain atomic
**Changes:**
add check !defined(__STDC_NO_ATOMICS__)
If the macro constant __STDC_NO_ATOMICS__(C11) is defined by the compiler,
the header <stdatomic.h>, the keyword _Atomic, and all of the names listed here
are not provided.
