- mem
-
A memory reference to FXSAVE area. The 512-bytes memory addressed by the reference must be 16-bytes aligned.
- save_mask
-
A bit mask specifying the extended states to be saved.
Saves the states of x87 FPU, MMX, XMM, YMM, and MXCSR registers to memory. The xsave64 intrinsic maps to XSAVE64 instruction, the xsavec64 intrinsic maps to XSAVEC64 instruction, and the xsaves64 intrinsic maps to XSAVES64 instruction. See the Intel® 64 and IA-32 Architectures Software Developer's Manual for information on how the three instructions differ.
