摘要： A computer implemented method, apparatus, and computer program product for compiling source code. The source code is scanned to identify a candidate region. A procedure control descriptor is corresponding to the candidate region is generated. The procedure control descriptor identifies, for the candidate region, a condition which, if true at runtime means that the candidate region can be specialized. Responsive to a determination during compile time that satisfaction of at least one condition will be known only at runtime, the procedure control descriptor is used to specialize the candidate region at compile time to create a first version of the candidate region for execution in a case where the condition is true and a second version of the candidate region for execution in a case where the condition is false. Also responsive to the determination, code is further generated to correctly select one of the first region and the second region at runtime.

摘要： A method of compiling source code. The method includes converting pointer-based access in the source code to array-based access in the source code in a first pass compilation of the source code. Information is collected for objects in the source code during the first pass compilation. Candidate objects in the source code are selected based on the collected information to form selected candidate objects. Global stride variables are created for the selected candidate objects. Memory allocation operations are updated for the selected candidate objects in a second pass compilation of the source code. Multiple-level pointer indirect references are replaced in the source code with multi-dimensional array indexed references for the selected candidate objects in the second pass compilation of the source code.

摘要： Computer implemented method, system and computer usable program code for cache management. A cache is provided, wherein the cache is viewed as a sorted array of data elements, wherein a top position of the array is a most recently used position of the array and a bottom position of the array is a least recently used position of the array. A memory access sequence is provided, and a training operation is performed with respect to a memory access of the memory access sequence to determine a type of memory access operation to be performed with respect to the memory access. Responsive to a result of the training operation, a cache replacement operation is performed using the determined memory access operation with respect to the memory access.

摘要： Inter-procedural strength reduction is provided by a mechanism of the present invention to improve data cache performance. During a forward pass, the present invention collects information of global variables and analyzes the usage pattern of global objects to select candidate computations for optimization. During a backward pass, the present invention remaps global objects into smaller size new global objects and generates more cache efficient code by replacing candidate computations with indirect or indexed reference of smaller global objects and inserting store operations to the new global objects for each computation that references the candidate global objects.

摘要： Optimizing program code in a static compiler by determining the live ranges of variables and determining which live ranges are candidates for moving code from the use site to the definition site of source code. Live ranges for variables in a flow graph are determined. Selected live ranges are determined as candidates in which code will be moved from a use site within the source code to a definition site within the source code. Optimization opportunities within the source code are identified based on the code motion.
