pref

Operands

imm, imm($reg)

Variants

Prefetch : Hints that the data at address ($t2 + offset) will be needed soon, so the hardware can begin moving it into cache. The first operand is the hint type. A prefetch is only ever a hint and never changes what a program computes; this simulator has no cache, so it does nothing. It is accepted so that compiler output assembles unchanged. pref 1,-100($t2)
