Data-Flow Based Detection of Loop Bounds
| pdf-format: |

Abstract
To calculate the WCET of a program, safe upper boundson the number of loop iterations for all loops in the program
are needed. As the manual annotation of all loops with such
bounds is difficult and time consuming, the WCET analyzer
aiT originally developed by Saarland University and AbsInt
GmbH uses static analysis to determine the needed bounds
as far as possible.
This paper describes a novel data-flow based analysis
for aiT to calculate the needed loop bounds on the assembler level. The new method is compared with a pattern
based loop analysis already in use by this tool.
