Abstract
Instructions are grouped into instruction groups based on optimizations that may be performed. An instruction is obtained, and a determination is made as to whether the instruction is to be included in a current instruction group or another instruction group. This determination is made based on whether the instruction is a candidate for optimization, such as decode time instruction optimization. If it is determined that the instruction is to be included in another group, then the other group is formed to include the instruction.
Claims10
A method of facilitating processing in a processing environment, said computer program product comprising:
- obtaining an instruction to be executed in the processing environment;
- determining whether the instruction is to be included in a current group of instructions or a new group of instructions, wherein the determining is based on whether the instruction is a candidate for optimization with another instruction according to an optimization criterion;
- based on determining the instruction is to be included in the new group of instructions, forming the new group of instructions, the new group of instructions including the instruction and the other instruction;
- and
- based on forming the new group of instructions, executing at least one instruction associated with the new group of instructions.
