Abstract: 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.

Abstract: A system of permitting stack allocation in a program with open-world features is described. The system includes an escape analysis module to (1) determine which objects of the program can be stack-allocated under a closed-world assumption and (2) analyze, after stack allocation, which stack allocation is invalidated due to the occurrence of an open-world feature. A stack allocation module is provided to stack-allocate these objects based on the determination of the escape analysis module. A stack allocation recovery module is provided to recover those invalidated stack allocations back to their original allocation in heap based on the analysis of the escape analysis module. A method of permitting stack allocation in a program with open-world features is also described.
