When should I use function inlining?

What is function inlining and when should I use it?

Function inlining is a technique where the compiler replaces a function call with the actual code of the function. You should use it when the function is small and called frequently, as it can reduce the overhead of function calls.

Are there any downsides to using function inlining?

Yes, inlining can increase the size of the binary if used excessively, which may lead to cache misses and negatively impact performance.

How do I decide if a function is suitable for inlining?

Consider the function's size, frequency of calls, and whether it has side effects. Small, frequently called functions without side effects are usually good candidates.

Can inlining affect debugging?

Yes, inlining can make debugging more challenging because the original function call is replaced with the function's code, making stack traces less clear.
