This can potentially improve performance by eliminating the overhead associated with function calls, such as stack frame creation and argument passing.
When the `alwaysinline` attribute is applied to a function, the programmer is essentially telling the compiler
However, it's important to note that `alwaysinline` is usually a hint, not a strict command. The compiler
The exact syntax and availability of the `alwaysinline` attribute vary between compilers. For instance, in GCC
