Hello! I have recently begun to use mingw-w64 via msys2 and I'm running into an issue compiling an external code due to the apparent absence of the "InterlockedCompareExchange128" intrinsic function. Specifically, this ordinarily appears to be defined in the <intrin.h> header for MSVC:
https://docs.microsoft.com/en-us/cpp/intrinsics/interlockedcompareexchange128?view=msvc-160 However this does not appear to be in the intrin.h header included in /mingw64/x86_64-w64-mingw32/include/intrin.h - the closest option appears to be _InterlockedCompare64Exchange128, which is not the same function signature: https://docs.microsoft.com/en-us/previous-versions/windows/desktop/legacy/ms683553(v=vs.85) Looking both at winnt.h and intrin.h, both seem to have this older version of the function signature but not the current version supported for x64-based applications. Moreover, it seems like this intrinsi has been supported in MSVC since at least MSVC 2015: https://docs.microsoft.com/en-us/cpp/intrinsics/x64-amd64-intrinsics-list?view=msvc-140 Does anyone know anything more about this, including possible workarounds? I am using gcc-10.3.0. To be honest, this is well outside of my domain; I am simply trying to get the Kokkos package (part of Trilinos) to compile and this issue is presently blocking me.
