Dear Sir, I want to understand the phase-ordering problem in compilers. My basic doubt is what is the difference between the pass and phase in compilers? As for as I know, Pass something that scans to through the input code snippet and does some transformation to it and whereas phases in the classicle compiler are main components/modules which are Lexical Analysis, Parsing, semantic analysis, IL code Generation, Code Optimization and code Generation. When it comes to phase-ordering in compilers is it actually pass ordering or phase-ordering? How the user can handle/alter phase-ordering in GCC? Is it only through changing the order of the optimization options fed to the compiler or by tweaking the pass_manager? Will there be any impact of repeating optimization options or reordering the optimization options in GCC?
