Available on x86-64 and target feature xsave,xsaves only.
Expand description

Performs a full or partial save of the enabled processor states to memory at mem_addr

xsaves differs from xsave in that it can save state components corresponding to bits set in IA32_XSS MSR and that it may use the modified optimization. State is saved based on bits [62:0] in save_mask and XCR0. mem_addr must be aligned on a 64-byte boundary.
