Vocabulary

Class description
Instruction that copies an 8 byte value from a XMM register to a memory location addressed by a normal register. This instruction is often turned into a cheaper ##store-memory instruction in the value-numbering pass.

base	Vreg that contains the base address.
offset	Offset in bytes from the address to where the data should be written.
rep	Value representation in the vector register.
src	Vreg that contains the item to set.
