__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.
This __declspec attribute has the function attribute equivalent
