摘要： Methods and apparatuses provide for referencing thread local variables (TLVs) with techniques such as stack address mapping. A method may involve a head pointer that points to a set of thread local variables (TLVs) of a thread. A method according to one embodiment may include an operation for storing the head pointer in a global data structure in a user space of a processing system. The head pointer may subsequently be retrieved from the global data structure and used to access one or more TLVs associated with the thread. In one embodiment, the head pointer is retrieved without executing any kernel system calls. In an example embodiment, the head pointer is stored in a global array, and a stack address for the thread is used to derive an index into the array. Other embodiments are described and claimed.

摘要： A method and system are provided for improving inlining using stack trace cache-based dynamic profiling. In one embodiment, a relationship map is provided to map a key representing a caller-callee relationship with a corresponding value indicating a frequency of call site executions. Whether a last stack frame of a stack frame trace is cached is determined. A caller-callee relationship is recorded if the last stack frame is not cached, wherein the caller-callee relationship is recorded in the relationship map, and the relationship map is updated with the recorded caller-callee relationship and then monitored via a recompilation scheduler, the monitoring to determine when a compilation or recompilation of callers and callees is to be performed. A turning on or turning off of dynamic profiling is conducted to perform partial unwinding of the frames in the stack trace.

摘要： An arrangement is provided for using a stack trace cache when performing root set enumeration in a stack of a thread during garbage collection. During the first root set enumeration in the stack, full stack unwinding may be performed and a stack trace cache may be created to cache stack trace information relating to stack frames. Subsequent sessions of root set enumeration in the stack may access and copy parts or the entire cached stack trace information instead of performing full stack unwinding.
