| | | | | | | | | concerning qualified declarator-ids. We now diagnose extraneous qualification at namespace scope (which we had previously missed) and diagnose these qualification errors for all kinds of declarations; it was rather uneven before. Fixes <rdar://problem/11135644>. llvm-svn: 153577

| | | | | | | | | | | search for the specialization (in a folding set) and, if not found form a *Decl that is then inserted into that folding set. In rare cases, the folding set may be reallocated between the search and the insertion, causing a crash. No test case, because triggering rehashing consistently in a small test case is not feasible.

* Move the emission of strict enum range metadata behind a flag (the sameChandler Carruth2012-03-277-3/+24
| | | | | | | | | | | | | | | | | | | | | flag as GCC uses: -fstrict-enums). There is a *lot* of code making unwarranted assumptions about the underlying type of enums, and it doesn't seem entirely reasonable to eagerly break all of it. Much more importantly, the current state of affairs is *very* good at optimizing based upon this information, which causes failures that are very distant from the actual enum. Before we push for enabling this by default, I think we need to implement -fcatch-undefined-behavior support for instrumenting and trapping whenever we store or load a value outside of the range. That way we can track down the misbehaving code very quickly. I discussed this with Rafael, and currently the only important cases he is aware of are the bool range-based optimizations which are staying hard enabled. We've not seen any issue with those either, and they are much more important for performance. llvm-svn: 153550

* [analyzer] Add an option to re-analyze a dead-end path without inlining.Anna Zaks2012-03-2715-77/+346
| | | | | | | | | | | | | | | | | | | | | The analyzer gives up path exploration under certain conditions. For example, when the same basic block has been visited more than 4 times. With inlining turned on, this could lead to decrease in code coverage. Specifically, if we give up inside the inlined function, the rest of parent's basic blocks will not get analyzed. This commit introduces an option to enable re-run along the failed path, in which we do not inline the last inlined call site. This is done by enqueueing the node before the processing of the inlined call site with a special policy encoded in the state. The policy tells us not to inline the call site along the path. This lead to ~10% increase in the number of paths analyzed. Even though we expected a much greater coverage improvement. The option is turned off by default for now. llvm-svn: 153534

We want the macro expansions to be considered as before-in-translation-unit for everything in the included file. -In the preprocessing record take into account that only inclusion directives can be encountered as "out-of-order" (by comparing the start of the range which for inclusions is the hash location) and use binary search if there is an extreme number of macro expansions in the include directive.

* Change RetainCountChecker to eagerly "escape" retained objects when they areTed Kremenek2012-03-273-1/+35
| | | | | | | | | | | | assigned to a struct. This is fallout from inlining results, which expose far more patterns where people stuff CF objects into structs and pass them around (and we can reason about it). The problem is that we don't have a general way to detect when values have escaped, so as an intermediate step we need to eagerly prune out such tracking. Fixes <rdar://problem/11104566>. llvm-svn: 153489
* When we see 'Class(X' or 'Class::Class(X' and we suspect that it names aRichard Smith2012-03-273-8/+62
| | | | | | | | | | | | | constructor, but X is not a known typename, check whether the tokens could possibly match the syntax of a declarator before concluding that it isn't a constructor. If it's definitely ill-formed, assume it is a constructor. Empirical evidence suggests that this pattern is much more often a constructor with a typoed (or not-yet-declared) type name than any of the other possibilities, so the extra cost of the check is not expected to be problematic. llvm-svn: 153488

* Forward-declared enumerations are now complete, except for an interactionRichard Smith2012-03-262-1/+2

* Add a special-case diagnostic for one of the more obnoxious special cases ofRichard Smith2012-03-263-0/+58
| | | | | | | | | | | | | | | unscoped enumeration members: an enumerator name which is visible in the out-of-class definition of a member of a templated class might not actually exist in the instantiation of that class, if the enumeration is also lexically defined outside the class definition and is explicitly specialized. Depending on the result of a CWG discussion, we may have a different resolution for a class of problems in this area, but this fixes the immediate issue of a crash-on-invalid / accepts-invalid (depending on +Asserts). Thanks to Johannes Schaub for digging into the standard wording to find how this case is currently specified to behave. llvm-svn: 153461
