摘要： Mechanisms for extracting data dependencies during runtime are provided. With these mechanisms, a portion of code having a loop is executed. A first parallel execution group is generated for the loop, the group comprising a subset of iterations of the loop less than a total number of iterations of the loop. The first parallel execution group is executed by executing each iteration in parallel. Store data for iterations are stored in corresponding store caches of the processor, Dependency checking logic of the processor determines, for each iteration, whether the iteration has a data dependence. Only the store data for stores where there was no data dependence determined are committed to memory.

摘要： Mechanisms are provided for evicting cache lines from an instruction cache of the data processing system. The mechanisms store, for a portion of code in a current cache line, a linked list of call sites that directly or indirectly target the portion of code in the current cache line. A determination is made as to whether the current cache line is to be evicted from the instruction cache. The linked list of call sites is processed to identify one or more rewritten branch instructions having associated branch stubs, that either directly or indirectly target the portion of code in the current cache line. In addition, the one or more rewritten branch instructions are rewritten to restore the one or more rewritten branch instructions to an original state based on information in the associated branch stubs.

摘要： Mechanisms are provided for dynamically rewriting branch instructions in a portion of code. The mechanisms execute a branch instruction in the portion of code. The mechanisms determine if a target instruction of the branch instruction, to which the branch instruction branches, is present in an instruction cache associated with the processor. Moreover, the mechanisms directly branch execution of the portion of code to the target instruction in the instruction cache, without intervention from an instruction cache runtime system, in response to a determination that the target instruction is present in the instruction cache. In addition, the mechanisms redirect execution of the portion of code to the instruction cache runtime system in response to a determination that the target instruction cannot be determined to be present in the instruction cache.

摘要： Mechanisms for performing data parallel function calls in code during runtime are provided. These mechanisms may operate to execute, in the processor, a portion of code having a data parallel function call to a target portion of code. The mechanisms may further operate to determine, at runtime by the processor, whether the target portion of code is a data parallel portion of code or a scalar portion of code and determine whether the calling code is data parallel code or scalar code. Moreover, the mechanisms may operate to execute the target portion of code based on the determination of whether the target portion of code is a data parallel portion of code or a scalar portion of code, and the determination of whether the calling code is data parallel code or scalar code.

摘要： Mechanisms are provided for arranging binary code to reduce instruction cache conflict misses. These mechanisms generate a call graph of a portion of code. Nodes and edges in the call graph are weighted to generate a weighted call graph. The weighted call graph is then partitioned according to the weights, affinities between nodes of the call graph, and the size of cache lines in an instruction cache of the data processing system, so that binary code associated with one or more subsets of nodes in the call graph are combined into individual cache lines based on the partitioning. The binary code corresponding to the partitioned call graph is then output for execution in a computing device.

摘要： Mechanisms are provided for rewriting branch instructions in a portion of code. The mechanisms receive a portion of source code having an original branch instruction. The mechanisms generate a branch stub for the original branch instruction. The branch stub stores information about the original branch instruction including an original target address of the original branch instruction. Moreover, the mechanisms rewrite the original branch instruction so that a target of the rewritten branch instruction references the branch stub. In addition, the mechanisms output compiled code including the rewritten branch instruction and the branch stub for execution by a computing device. The branch stub is utilized by the computing device at runtime to determine if execution of the rewritten branch instruction can be redirected directly to a target instruction corresponding to the original target address in an instruction cache of the computing device without intervention by an instruction cache runtime system.
