The instruction has two forms: ptr.d (data) and ptr.i (instruction). The intrinsics emit the similarly named form of the instruction. Unlike __ptcg and __ptcga, the operation is local to the processor.

For more information, see the Intel IPF documentation. These routines are only available as intrinsics.
