摘要： Various embodiments are generally directed to techniques for compiler sheltered nonvolatile memory (NVM) stores, such as based on demarcated atomic persistence regions in source code, for instance. Some embodiments are particularly related to a compiler that effectively shelters updates to NVM-based variables in a compiler implemented register, or register file, until the compiler has recorded undo values into a temporary but nonvolatile log range.

摘要： Embodiments are directed toward techniques to detect a first function associated with an address space initiating a call instruction to a second function in the address space, the first function to call the second function in a deprivileged mode of operation, and define accessible address ranges for segments of the address space for the second function, each segment to a have a different address range in the address space where the second function is permitted to access in the deprivileged mode of operation, Embodiments include switching to the stack associated with the second address space and the second function, and initiating execution of the second function in the deprivileged mode of operation
