20130086337MAINTAINING A TIMESTAMP-INDEXED RECORD OF MEMORY ACCESS OPERATIONS - A memory management system determines a timestamp for a memory access operation that accesses a block of data, and uses the timestamp to access a timestamp-indexed record. The timestamp-indexed record includes a plurality of record arrays, each of which corresponds to a different time range, and includes one or more record entries of a different array-specific time duration. The system selects a record entry that indicates a time range associated with the timestamp, and that indicates an amount of memory accessed during the indicated time range. The system then updates the selected record entry to account for the memory size of the block of data.04-04-2013
20130086338LINKING CODE FOR AN ENHANCED APPLICATION BINARY INTERFACE (ABI) WITH DECODE TIME INSTRUCTION OPTIMIZATION - A code sequence made up multiple instructions and specifying an offset from a base address is identified in an object file.

It is determined that the offset location is within a specified distance of the base address and that a replacement of the identified code sequence with a replacement code sequence will not alter program semantics. The identified code sequence in the object file is replaced with the replacement code sequence that includes a no-operation (NOP) instruction or having fewer instructions than the identified code sequence. Linked executable code is generated based on the object file and the linked executable code is emitted.04-04-2013
