Software techniques are employed to mitigate soft errors. In particular, a compiler (or other executable code generator) may emit otherwise duplicative instructions targeting otherwise duplicative storage locations to facilitate run-time detection and, in some cases, mitigation of soft errors. In general, a compiler emits a program sequence of primary instructions that correspond to source code. However, in addition, for those primary instructions that target storage susceptible to soft errors, the compiler may emit corresponding additional instructions that target additional storage. In some implementations the additional storage is not itself susceptible to soft errors. However, more generally, implementations may tolerate soft errors affecting the additional storage, as long as such soft errors are generally uncorrelated with those affecting the storage targeted by the primary instructions.
