// C and C++ handle inline functions differently. In C++, an inline function is
// defined in just the header file, potentially emitted in multiple compilation
// units (in cases the compiler did not inline), but each copy must be identical
// to satisfy ODR. In C, a non-static inline must be manually emitted in exactly
// one compilation unit with a separate extern inline declaration.
//
// In both languages, exported inline functions referencing file-local symbols
// are problematic. C forbids this altogether (though GCC and Clang seem not to
// enforce it). It works in C++, but ODR requires the definitions be identical,
// including all names in the definitions resolving to the "same entity". In
// practice, this is unlikely to be a problem, but an inline function that
// returns a pointer to a file-local symbol
// could compile oddly.
//
// Historically, we used static inline in headers. However, to satisfy ODR, use
// plain inline in C++, to allow inline consumer functions to call our header
// functions. Plain inline would also work better with C99 inline, but that is
// not used much in practice, extern inline is tedious, and there are conflicts
// with the old gnu89 model:
// https://stackoverflow.com/questions/216510/extern-inline
//
// So in C, always use static inline, whereas in C++, use static inline
// only if |BORINGSSL_ALWAYS_USE_STATIC_INLINE| is defined (which may be useful
// for some FFI integrations in conjunction with |BORINGSSL_PREFIX|, as static
// inline functions are local to the compilation unit and need no prefix).
