|
When evaluated, this vm instruction adds the register source integer
value (left shifted by the number of bits in the specified datatype immediate
value) to the register target pointer value and places the resulting
pointer in the target register. The result will be returned as a type pointer.
This instruction may return an Error value. After the operation, the Instruction
Pointer is promoted. The operation of this vm instruction is expressed in the
following C expression:
The valid datatype arguments are any immediate integer value,
indicating the number of bits to left shift, or any one of the following
symbolic shift sizes:

AIS Lambdas are designed to be write-once-run-anywhere executable objects. This is accomplished via the virtual machine concept of software Lambda execution. Lambda virtual machines are designed to be mapped onto the actual host microchip at the server location, providing faithful Lambda execution wherever the Lambda may travel on the Internet. There are currently several virtual machines operating within Analytic Information Server. The DRM virtual machine uses a Dynamically typed Register Machine model to provide portable Lambda execution from high level dynamically typed instructions all the way to super fast microchip-level register execution. The DRM virtual machine runs in emulation mode during the testing and debug phases of Lambda development, and there is an AIS Lambda debugger available for Lambdas running on this virtual machine. During the final release phases of Lambda development, DRM virtual machine Lambdas are automatically converted to the NATIVE virtual machine on the host computer, using the just-in-time compiler. The NATIVE virtual machine is a faithful machine language translation of the execution rules in the DRM virtual machine onto the actual host microchip at the server location. NATIVE virtual machine execution runs at microchip-level execution speeds.
