◆ getMappedObjectPointer()

Value getMappedObjectPointer	(	Location	loc,

		ConversionPatternRewriter &	rewriter )

static

The address of the mapped object, as the runtime expects to receive it.

Privatized storage only ever exists on the device, so there is no host address to give. A device address names storage the runtime must not look up, and an object mapped by value has no address at all, so both are handed over in a slot the runtime reads them from.
