INSTRUCTIONS AND SUPPORT FOR CONDITIONAL COMPARISON AND TEST

Techniques for conditional test or comparison using a single instruction are described. An example instruction includes one or more fields to identify a first source operand location, one or more fields to identify a first source operand location, and an opcode to indicate execution circuitry is to...

More Information
Summary:Techniques for conditional test or comparison using a single instruction are described. An example instruction includes one or more fields to identify a first source operand location, one or more fields to identify a first source operand location, and an opcode to indicate execution circuitry is to conditionally perform a comparison of data from the identified first source operand to the identified second source operand based at least in part on an evaluation of a source condition code and update a flags register, wherein a payload of the prefix is to provide most significant bits to identify at least one of the first and second source operand locations.
