Questions tagged [inline]

Use this tag for questions specifically about the effects of the inline keyword, together with the appropriate language tag.

Inline, or inline expansion, is a programming language optimization that inserts the complete body of the function in every place that the function is called. Depending on the programming language, this may be implemented by the compiler, manually or by a keyword.

Historically, in the C and C++ programming languages, an inline function is a function upon which the compiler has been requested to perform inline expansion. In other words, the programmer has requested that the compiler insert the complete body of the function in every place that the function is called, rather than generating code to call the function in the one place it is defined. However, modern compilers usually use their own heuristics and ignore the request. Thus, the inline keyword is now mostly used for its effects on the One Definition Rule.

Inline expansion is used to eliminate the time overhead when a function is called. It is typically used for functions that execute frequently. It also has a space benefit for very small functions, and is an enabling transformation for other optimizations.

Do I need to bother with INLINE/INLINABLE pragmas for small, exported, functions, or will GHC do it for me?

I have a module which collects and exports a bunch of small functions such as: fromEither :: (MonadError e m) => Either e a -> m a fromEither = either throwError return or withError :: MonadError e m => (e -> e) -> m a -> m a withError = flip…

Should I define static inline methods in header file?

I've read about how it is usually best not to define anything in header files because redundant copies are made for every other file that includes the header file. However, in the case of static inline methods, it appears that I have to define it on…

Force a function to be inline in Clang/LLVM

Is there a way to force an inline function in Clang/LLVM? AFAIK, the following is just a hint to the compiler but it can ignore the request. __attribute__((always_inline)) I don’t mind that the compilation will fail if it can’t inline the function.
