4.2.3 __declspec(noinline)
The __declspec(noinline) attribute suppresses the inlining of a function at the call
points of the function.
__declspec(noinline) can also be applied to constant data, to prevent the compiler from
using the value for optimization purposes, without affecting its placement in the object.
This is a feature that can be used for patchable constants, that is, data that is later
patched to a different value. It is an error to try to use such constants in a context where
a constant value is required. For example, an array dimension.
Note
This __declspec attribute has the function attribute equivalent
__attribute__((noinline)).
Examples
/* Prevent y being used for optimization */
__declspec(noinline) const int y = 5;
/* Suppress inlining of foo() wherever foo() is called */
__declspec(noinline) int foo(void);
