Marian Buschsieweke	29e963bd95	build system: deprecate RIOT_MCU predefined macro ... This re-adds `RIOT_MCU` as alias for `RIOT_CPU` and marks it as deprecated. That should make life easier for downstream apps that may still use `RIOT_CPU`.	2024-09-28 18:32:49 +02:00
Marian Buschsieweke	cadbbb6e95	build system: Add MACRO_DEPRECATED macro ... Adding this macro in the definition of a macro causes a warning about the deprecation to be emitted when used (and a build failure with `WERROR=1`). This is useful as no other means to deprecate preprocessor macros are provided. The macro will be defined empty for compilers that are not GCC or clang.	2024-09-28 18:32:49 +02:00
Marian Buschsieweke	906e2c3234	build system: document riotbuid.h ... This adds a `riotbuild-prefix.h` that is added to the `riotbuild.h` and processed by Doxygen. It solves two problems: 1. The pre-defined macros where previously fully undocumented, but may be useful to real world applications 2. It provides a place where backward compatibility aliases can be added with a deprecation notice	2024-09-28 18:32:49 +02:00
