2013-04-02Fix some inconsistent use of indentation.Daniel Jasper
Basically we have always special-cased the top-level statement of an unwrapped line (the one with ParenLevel == 0) and that lead to several inconsistencies. All added tests were formatted in a strange way, for example: Before: aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa .aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa .aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa .aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa(); if (aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa .aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa .aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa .aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa()) { } After: aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa .aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa .aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa .aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa(); if (aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa .aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa .aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa .aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa()) { } git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@178542 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-02Add -Wstatic-local-in-inline, which warns about using a static localJohn McCall
variable in a C99 inline (but not static-inline or extern-inline) function definition. The standard doesn't actually say that this doesn't apply to "extern inline" definitions, but that seems like a useful extension, and it at least doesn't have the obvious flaw that a static mutable variable in an externally-available definition does. rdar://13535367 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@178520 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-02[analyzer] Teach invalidateRegions that regions within LazyCompoundVal need ↵Anna Zaks
to be invalidated Refactor invalidateRegions to take SVals instead of Regions as input and teach RegionStore about processing LazyCompoundVal as a top-level “escaping” value. This addresses several false positives that get triggered by the NewDelete checker, but the underlying issue is reproducible with other checkers as well (for example, MallocChecker). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@178518 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-02[analyzer] For now, don't inline [cd]tors of C++ containers.Jordan Rose
This is a heuristic to make up for the fact that the analyzer doesn't model C++ containers very well. One example is modeling that 'std::distance(I, E) == 0' implies 'I == E'. In the future, it would be nice to model this explicitly, but for now it just results in a lot of false positives. The actual heuristic checks if the base type has a member named 'begin' or 'iterator'. If so, we treat the constructors and destructors of that type as opaque, rather than inlining them. This is intended to drastically reduce the number of false positives reported with experimental destructor support turned on. We can tweak the heuristic in the future, but we'd rather err on the side of false negatives for now. <rdar://problem/13497258> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@178516 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-02[analyzer] Cache whether a function is generally inlineable.Jordan Rose
Certain properties of a function can determine ahead of time whether or not the function is inlineable, such as its kind, its signature, or its location. We can cache this value in the FunctionSummaries map to avoid rechecking these static properties for every call. Note that the analyzer may still decide not to inline a specific call to a function because of the particular dynamic properties of the call along the current path. No intended functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@178515 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-02[analyzer] Use inline storage in the FunctionSummary DenseMap.Jordan Rose
The summaries lasted for the lifetime of the map anyway; no reason to include an extra allocation. Also, use SmallBitVector instead of BitVector to track the visited basic blocks -- most functions will have less than 64 basic blocks -- and use bitfields for the other fields to reduce the size of the structure. No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@178514 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-02[analyzer] Allow suppressing diagnostics reported within the 'std' namespaceJordan Rose
This is controlled by the 'suppress-c++-stdlib' analyzer-config flag. It is currently off by default. This is more suppression than we'd like to do, since obviously there can be user-caused issues within 'std', but it gives us the option to wield a large hammer to suppress false positives the user likely can't work around. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@178513 91177308-0d34-0410-b5e6-96231b3b80d8
