Techenical review of Peephole Optimization Technique for analysis and review of Compiler Design and ConstructionIn 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 ...
adjacent operations in thellirmay not operate on the same values. In fact, as target machines offer more instruction-levelparallelism, a compiler's front end and optimizer must generateirprograms that have

Optimization functions are crucial to compiler design. Generally, compiler optimization divides into machine-independent optimization based on the intermediate language and machine-dependent optimization based on the object code. In order to make use of the characteristics of the target machine, this ...
Transformations over assembly code are common in many compilers. These transformations are also some of the most bug-dense compiler components. Such bugs could be eliminated by formally verifying the compiler, but state-of-theart formally verified compilers like CompCert do not support assembly-level...

When compared to the native compiler, our translated code achieves median performance of 67% on large benchmarks and in some small stress tests actually outperforms the native compiler. We also report comparisons with the open source binary translator Qemu and a commercial tool, Apple's Rosetta....
