Function Documentation

_fxrstor()

__inline__ void __DEFAULT_FN_ATTRS _fxrstor ( void * __p )

static

Restores the XMM, MMX, MXCSR and x87 FPU registers from the 512-byte memory region pointed to by the input parameter __p.

The contents of this memory region should have been written to by a previous _fxsave or _fxsave64 intrinsic.

This intrinsic corresponds to the FXRSTOR instruction.

Parameters

__p	A pointer to a 512-byte memory region. The beginning of this memory region should be aligned on a 16-byte boundary.

_fxsave()

__inline__ void __DEFAULT_FN_ATTRS _fxsave ( void * __p )

static

Saves the XMM, MMX, MXCSR and x87 FPU registers into a 512-byte memory region pointed to by the input parameter __p.

This intrinsic corresponds to the FXSAVE instruction.

Parameters

__p	A pointer to a 512-byte memory region. The beginning of this memory region should be aligned on a 16-byte boundary.
