Summary

0001388: Frama-C should not honor -save if when it aborts

Description

This is problematic because it complicates the use of Makefile. Typical pattern: Makefile: foo.sav: $(DEPS) frama-c -save $@ make foo.sav make foo.sav make: `foo.sav' is up to date. Frama-c not creating a foo.sav on the first invocation would solve the problem. What do you think? Are there some good cases when dumping partial saves is useful? In fact, what do those saves contain, since at least one plugin failed. Is the internal state really consistent?

Notes
(0003787) signoles (manager) 2013-04-11 13:22	Actually whether the state is consistent depends on when Frama-C aborts: either the saved state is the last consistent one, or it is at least partially inconsistent. In the former case, it may be really useful for debugging. Even in the latter case, it could be useful depending on the status of the inconsistency. So I understand your issue but, since the state may be useful, I'm not sure it is a good idea to prevent saving anytime Frama-C fails. Maybe we could adopt the following classification: - on normal exit: save (of course) - on Sys.break, system error, user error or feature request: do not save - on fatal error or unexpected error: save, but slighly change the generated filename [f.sav] to [f.crash.sav] or something similar. What do you think of this proposal?
