| Summary | 0001415: Logging just enough information for failed pre-conditions | ||||||||
| Description | There was a bit of a discussion over an analysis made on an example provided by a StackOverflow user: http://stackoverflow.com/a/16356519/139746 The current message is: .../libc/string.h:54:[value] Function memcpy: precondition got status invalid. That is a bit frustrating. The localization of the call to memcpy() can be found just above in the log: [value] computing for function memcpy <- main. Called from mem.c:13. but the exact nature of the detected issue is only printed as a reference to libc/string.h, a file that the user did not even provide emself. There are at least two solutions suggested by the discussion: - annotate the libc preconditions with nice labels, and when a pre-condition fails, print any label it may have, or - print the entire ACSL pre-condition that failed, including any label it may have. | ||||||||

Properties line numbers will be shown together with the property name. This also require updating the libc to be useful, though. |
