Classification of Code Annotations and Discussion of Compiler-Support for Worst-Case Execution Time Analysis

Tools for worst-case execution time (WCET) analysis request several code annotations from the user. However, most of them could be avoided or being annotated more comfortably if the compilers would support WCET analysis. This paper provides a clear categorization of code annotations for WCET analysis and discusses the positive impact on code annotations a compiler-support on WCET analysis would have
