[for] obs - studio project at compile time, not to identify iso_volatile

Obs - studio project after download, use CMake generated VS2017 project, running at compile time, error, are iso_volatile_loadXX related

Online, but could not find related information, every brother please help and see what to do

reference 1/f, the truth is right or wrong response:

have no link to the corresponding library

When I was in cmake, indeed some libraries have no link,
Below is CMAKE compiled content, don't identify iso_volatile_load32, which library is?

The Intrinsic Functions provides On Alpha - the Overview
The Intrinsic functions provides (also known as intrinsics) are the function calls that the compiler resolves directly, by generating code, rather than by calling an external function. The Alpha version of the compiler supports a number of intrinsics.

With all the intrinsics, you must explicitly enable the intrinsic before calling it, by using it With the compiler option or the intrinsic pragma. The general syntax for using this pragma is:

# pragma intrinsic (intrinsic - name)

For example, to enable the use of the _InterlockedIncrement intrinsic, include a pragma to, along with the declaration of the function:

Long _InterlockedIncrement (long *);
# pragma intrinsic (_InterlockedIncrement)

The intrinsic functions provides listed in The following sections correspond one - for - one with existing instructions or PAL calls in The Alpha architecture. These functions provides assume that The following type definitions apply:

Typedef signed _ _int 64 int 64;
Typedef unsigned _ 64 uint64 _int;
