WebSep 9, 2024 · What is type checking in compiler design? A compiler must check that the source program follows both syntactic and semantic conventions of the source language. This checking, called static checking, detects and reports programming errors. How Lex tool is used in compiler design? Lex is a program that generates lexical analyzer. WebIn this article, we propose a novel technique for quantifying compiler-internal events in the optimized code, reducing the profiling perturbation on compiler optimizations. Our technique achieves this by instrumenting the program from within the compiler, and by delaying the instrumentation until the point in the compilation pipeline after ... fmg dailymotion
