Abstract
Instruction execution is controlled by a single test that determines whether processing should continue in mainline processing or fall through to a test set. The single test compares a dynamically set variable to an instruction counter. If the test is met, mainline processing continues. Otherwise, processing falls through to a test set.
Claims20
An article of manufacture comprising:
- at least one computer usable medium having computer readable program code logic to control instruction execution in a processing environment, said computer readable program code logic when executing performing the following:
- executing an instruction routine of an instruction stream;
- employing, in response to executing the instruction routine, a single test to determine whether processing is to continue to another instruction routine of the instruction stream or fall through to a test set;
- and
- executing the another instruction routine or the test set, in response to the determination.
A method of controlling instruction execution in a processing environment, said method comprising:
- executing an instruction routine of an instruction stream;
- employing, in response to executing the instruction routine, a single test to determine whether processing is to continue to another instruction routine of the instruction stream or fall through to a test set;
- and
- executing the another instruction routine or the test set, in response to the determination.
A system of controlling instruction execution in a processing environment, said system comprising:
- an instruction routine of an instruction stream;
- a routine to employ, in response to executing the instruction routine, a single test to determine whether processing is to continue to another instruction routine of the instruction stream or fall through to a test set;
- and
- a processor to execute the another instruction routine or the test set, in response to the determination.
