Abstract: A method of compressing instructions in a program may include extracting unique bit patterns from the instructions in the program and constructing a linear programming formulation or an integer programming formulation from the unique bit patterns, the instructions, and/or the size of a memory storage. The linear programming formulation or the integer programming formulation may be solved to produce a solution. The method may include compressing at least some of the instructions based on the solution by storing at least some of the unique bit patterns in a memory and placing corresponding indices to the memory in new compressed instructions.

Abstract: A method to optimize speculative parallel thread execution comprises selecting a plurality of partition candidate pairs for speculative parallel thread execution, transforming each partition candidate pair of the plurality of partition candidate pairs to improve the expected performance gain of each pair, and selecting a set of one or more transformed partition candidate pairs that do not interfere with each other and produce a maximum expected performance gain.

Abstract: An apparatus, method, and program product for optimizing code that contains dynamically-allocated memory. The aliasing behavior of internal pointers of dynamically-allocated memory is used to disambiguate memory accesses and to eliminate false data dependencies. It is determined whether a dynamically-allocated array will behave like a statically-allocated array throughout the entire program execution once it has been allocated. This determination is used to improve the instruction scheduling efficiency, which yields better performance.
Abstract translation: 一种用于优化包含动态分配内存的代码的设备，方法和程序产品。 动态分配内存的内部指针的混叠行为用于消除内存访问歧义并消除虚假的数据依赖性。 一旦动态分配的数组被分配，整个程序执行过程中，动态分配的数组是否会像一个静态分配的数组。 该决定用于提高指令调度效率，从而产生更好的性能。

Abstract: In some embodiments, a data structure may be received in a first processing system. The data structure may represent a plurality of instructions for a second processing system. For at least one instruction of the plurality of instructions, a determination may be made as to whether the instruction can be replaced by a compact instruction for the second processing system. A compact instruction may be generated if the instruction can be replaced by a compact instruction. In some embodiments, an instruction may be received in a processing system. A determination may be made as to whether the instruction is a compact instruction. A decompacted instruction may be generated if the instruction is a compact instruction.
