Binary optimizer
A binary optimizer, also known as an object code optimizer, takes a program's object code or machine code either from a linked executable binary file, or from live program memory, and produces sections of optimized code, invoked through either redirection or code replacement, that is functionally equivalent yet more performant. Program speedup is a common optimization goal. Some are intended to modernize old binaries to take better advantage of updated hardware, while others lean heavily on profile-guided optimization and interprocedural optimization to deliver performance gains. Some utilize run-time mechanisms to introspectively improve performance using techniques similar to JIT compilers.
