vmopt
vmopt
|
When evaluated, this vm instruction either starts or stops the AIS Lisp compiler
from optimizing all Assembler instructions. Issuing a (vmopt start:) instruction causes the AIS Lisp compiler to optimize all
Assembler instructions issued, between this (vmopt start:) instruction, and the next
(vmopt stop:) instruction. Issuing a (vmopt stop:) instruction causes the AIS Lisp
compiler to compile "as is" all Assembler instructions issued, between this
(vmopt stop:) instruction, and the next (vmopt start:) instruction
The default state of the AIS Lisp compiler when entering any Lambda
(lambda expression) is optimization ON.
The vmopt instruction is a compiler directive only and is never generated in the
Lambda pcode vector.
The valid commands for this instruction are as follows.

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.
