August 13, 2025 Commented Hello, As stated explicitly in the C17 standard (7.17.1 6.) It is unspecified whether any generic function declared in is a macro or an identifier declared with external linkage. The compiler may expand the function inline or it may rely on external implementation. This behavior may also depend not only on the function but on the argument types the function was called with. For example: unsigned int flags = 0b00000001; unsigned int old_flags = atomic_fetch_or(&flags, 0b00000100); will be expanded inline and it will link successfully. The following, however, will fall back to a library call and result in the linker error you encountered: unsigned char flags = 0b00000001; unsigned char old_flags = atomic_fetch_or(&flags, 0b00000100); There are no macros to check whether an inline expansion or a library call will be used. The current implementation of the compiler for RX expands inline only the 4 byte variant of the function. Please let us know if we can be of assistance with any other issues. Best regards, The Open Source Tools Team
