Abstract: Instruction sets in computing environments may execute within one of several domains, such as a natively executing domain, an interpretively executing domain, and a debugging executing domain. These domains may store values in a shared region of memory in different ways. It may be difficult to perform operations on such values, particularly if a domain that generated a particular value cannot be identified or no longer exist, which may obstruct shared accessing of values and evaluative tasks such as stack walks. Instead, accessors may be associated with a stored value that perform various operations (such as low-level assembly instructions like Load, Store, and Compare) according to the standards of the value-generating domain, and domains may be configured to operate on the value through the accessors. This configuration may promote consistent accessing of values without having to identify or consult the value-generating domain or reconfiguring the instruction sets.

Abstract: Within the field of computing, many scenarios involve the execution of an instruction set within a domain that is configured to support an execution context. However, various portions of the instruction set may be preferably executed in different domains, such as for promoting performance and for providing debugging features like the ability to simulate execution of a debuggee function without incurring side-effects in the debuggee. Portions of the instruction set may therefore be executed in different domains by inserting domain switch points in the instruction set specifying a target domain. The instruction set may then initiate execution in an initial domain, and upon reaching a domain switch point, may transition to the target domain. In some embodiments, the domain switch points may be automatically inserted into the target instruction set based on various domain switch criterion, such as performance, reliability, and affinity of an instruction with a particular domain.
