recompilers
Recompilers are software systems that translate code from one instruction set architecture (ISA) to another, typically to run software on hardware different from the original target. They may operate on binaries or on intermediate representations, and they are used to improve portability, performance, or both. Recompilation can occur offline, producing a retargeted executable, or online, as code is executed.
There are two main modes: static recompilation and dynamic recompilation. Static recompilers translate code before execution
Applications include emulation of legacy hardware, virtualization, and performance enhancement for interpreters or virtual machines. Recompilers
Key challenges include ensuring correctness across complex architectures, handling dynamic code generation, memory management, and synchronization
