# C++ build test

This build-only app can be used to check if certain headers, macros or features can be successfully compiled in a C++ source file.

To add a new test, create a new file `main/test_<name>.cpp` and add it to main/CMakeLists.txt.

If you need to check specific compiler flags, use `set_source_files_properties` CMake function to adjust the compilation flags for the given source file.

soc: make register access macros compatible with C++20 In C++20, using the result of an assignment to a 'volatile' value is deprecated. Breaking change: register "setter" or modification macros can no longer be used as expressions.
