Ben Niu b8d1857f0d [MSVC-specific] Define EIGEN_ARCH_x86_64 for native x64 (_M_X64 is defined and _M_ARM64EC is not), and define EIGEN_ARCH_ARM64 for both the native ARM64 (_M_ARM64 is defined) or ARM64EC (_M_ARM64EC is defined). _M_ARM64EC is defined when the code is compiled by MSVC for ARM64EC, a new ARM64 ABI designed to be compatible with x64 application emulation on ARM64. If _M_ARM64EC is defined, _M_X64 and _M_AMD64 are also defined, so x64-specific code (especially intrinsics) is also compiled to ARM64 instructions (compliant with the ARM64EC ABI) for maximum x64 compatibility. Although a majority of x64-specific intrinsics can emulated by ARM64 instructions, it is still a good to simply recompile the native ARM64 code paths to ARM64EC for pure computation tasks, for performance reasons.
