Now we consider additional defect patterns that I would classify as "basic" because they are clearly avoidable with good language design and relatively easy to detect with static analysis. However, these are generally more common in code written by experienced programmers than the patterns we saw i...
A method and apparatus for performing compiler optimizations is described. The method determines one or more impossible values for a variable in a program code based on a plurality of values of the variable. The method propagates the one or more impossible values for the variable throughout the...
Many compilers detect (and eliminate) unreachable code. Java’s compiler actually considers many unreachable statements to be a compilation error. This task answers the question: Are there existing files with unreachable statements? A solution to this task is shown in Figure 20.13. Sign in to ...
Note that Tint will need to consider unreachable-code as a warning anyway while transitioning to the new behavioural analysis, as the old specificationrequiredall functions to end in a return, and now this may be treated as an error. Example: ...
Description: $Title Describe your problem(s) In the current implementation, we only remove the code line with the diagnostic. However, we need to remove leading minutiae and the lines following the diagnostic code line which are also unr...
