In term of Compiler optimization, classical compilers implemented with an effective optimization technique called Peephole optimization. In the early stage of the implementation of this technique basically applied using string pattern matching performed on the regular expression and which are known as ...
Peephole optimizationcan form the basis of a fast and effective instruction selector. A peephole selector consists of a template-driven expander that translates the compiler'sirinto a more detailed low-levelir; a simplifier that uses forward substitution, algebraic simplification,constant propagation, a...

A problem related to optimization of ?le system logs is compiler peephole optimization [2, 9, 10], used to remove redundant instructions from assembly code when a program written in a high level language is compiled. 3. Design The system we have built is designed to be used with a ...
Peek contributes four new components: a lower level semantics for CompCert x86 syntax, a liveness analysis, a library for expressing and verifying peephole optimizations, and a verified peephole optimization pass built into CompCert. Each of these is accompanied by a correctness proof in Coq against...
