The technology is generally directed to detecting silent data corruption by selectively re-executing instructions. A renamer may receive decoded instructions from an instruction cache. The renamer may identify one or more of the decoded instructions that can be performed out of order. The reorder buffer may be configured to track instructions that are to be re-executed for purposes of computing their value a second time and comparing the value from the second computation with a value from a first computation. Prior to retiring, or completing, an instruction, an initial result of executing the instruction a first time may be compared with a re-execution result of re-executing the instruction a second or nth time. If the comparison indicates there is a different initial result than the re-execution result, an indication of possible silent data corruption may be generated for the instruction.

A code obfuscation tool has been created to safely rename strings within metadata sections of an executable file or binary to obscure program functionality and structure that may be revealed by class metadata in the binary. The code obfuscation tool parses metadata sections of the binary that have references to metadata that can be potentially renamed safely and locates the corresponding strings. The code obfuscation tool identifies from predetermined metadata sections metadata that is unsafe to rename. The code obfuscation tool evaluates each string that is a candidate for renaming against heuristics-based renaming rules and the determined unsafe strings to identify strings that are safe to rename. The code obfuscation tool generates a new name for each string determined as safe to rename based on renaming constraints. The code obfuscation tool creates a mapping structure that tracks renaming of strings and uses the mapping structure for consistent renaming of string.
