2013-02-25Add a front-end test case for r176036.Chad Rosier
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@176038 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-25Fix empty declaration printing.Michael Han
Don't print the semicolon when visiting an empty declaration because the semicolon will be printed as a terminator later. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@176035 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-25[analyzer] Base regions may be invalid when layered on symbolic regions.Jordan Rose
While RegionStore checks to make sure casts on TypedValueRegions are valid, it does not do the same for SymbolicRegions, which do not have perfect type info anyway. Additionally, MemRegion::getAsOffset does not take a ProgramState, so it can't use dynamic type info to determine a better type for the regions. (This could also be dangerous if the type of a super-region changes!) Account for this by checking that a base object region is valid on top of a symbolic region, and falling back to "symbolic offset" mode if not. Fixes PR15345. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@176034 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-25Re-add hack that caused regression.Daniel Jasper
This fixes llvm.org/PR15350. Before: Constructor(int Parameter = 0) : aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa(aaaaaaaaaaaaaaaaa), aaaaaaaaaaaa(aaaaaaaaaaaaaaaaa) {} After: Constructor(int Parameter = 0) : aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa(aaaaaaaaaaaaaaaaa), aaaaaaaaaaaa(aaaaaaaaaaaaaaaaa) {} I think the correct solution is to put the VariablePos into ParenState, not LineState. Added FIXME. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@176027 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-25Adding hasDeclaration overload for TemplateSpecializationTypeEdwin Vane
TemplateSpecializationType doesn't quite have getDecl(). Need to go through TemplateName to get a TemplateDecl. Added test cases for the hasDeclaration() overload for TemplateSpecializationType. Also introduced the type matcher templateSpecializationType() used by the new hasDeclaration() test case. Updated LibASTMatchersReference.

2013-02-25Support in hasDeclaration for types with getDecl()Edwin Vane
Re-introducing r175532. The has_getDecl metafunction didn't compile with Visual Studio. This revision uses approaches has_getDecl from a different angle that isn't a problem for Visual Studio.

2013-02-25[analyzer] Relax assumption in FindLastStoreBRVisitor that the thing we are ↵Ted Kremenek
looking for is always a VarRegion. This was triggering assertion failures when analyzing the LLVM codebase. This is fallout from r175988. I've got delta chewing away on a test case, but I wanted the fix to go in now. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@176011 91177308-0d34-0410-b5e6-96231b3b80d8

ExplodedNode pruning. r175988 modified the ExplodedGraph trimming algorithm to retain all nodes for "lvalue" expressions. This patch refines that notion to only "interesting" expressions that would be used for diagnostics. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@176010 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-24Allow breaking between a type and name in variable declarations.Daniel Jasper
This fixes llvm.org/PR14967 and is generall necessary to avoid situations where the column limit is exceeded. The challenge is restricting such lines splits, otherwise clang-format suddenly starts breaking at bad places. Before: ReallyLongReturnType<TemplateParam1, TemplateParam2> ReallyReallyLongFunctionName( const std::string &SomeParameter, const SomeType<string, SomeOtherTemplateParameter> &ReallyReallyLongParameterName, const SomeType<string, SomeOtherTemplateParameter> &AnotherLongParameterName) {} After: ReallyLongReturnType<TemplateParam1, TemplateParam2> ReallyReallyLongFunctionName( const std::string &SomeParameter, const SomeType<string, SomeOtherTemplateParameter> & ReallyReallyLongParameterName, const SomeType<string, SomeOtherTemplateParameter> & AnotherLongParameterName) {} git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@175999 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-24[analyzer] tracking stores/constraints now works for ObjC ivars or struct ↵Ted Kremenek
fields. This required more changes than I originally expected: - ObjCIvarRegion implements "canPrintPretty" et al - DereferenceChecker indicates the null pointer source is an ivar - bugreporter::trackNullOrUndefValue() uses an alternate algorithm to compute the location region to track by scouring the ExplodedGraph. This allows us to get the actual MemRegion for variables, ivars, fields, etc. We only hand construct a VarRegion for C++ references. - ExplodedGraph no longer drops nodes for expressions that are marked 'lvalue'. This is to facilitate the logic in the previous bullet. This may lead to a slight increase in size in the ExplodedGraph, which I have not measured, but it is likely not to be a big deal. I have validated each of the changed plist output. Fixes <rdar://problem/12114812> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@175988 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-24Add "KnownSVal" to represent SVals that cannot be UnknownSVal.Ted Kremenek

2013-02-23Better formatting of conditional expressions.Daniel Jasper
In conditional expressions, if the condition is split over multiple lines, also break before both operands. This prevents formattings like: aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa == aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa ? b : c; Which are bad, because they suggestion incorrect operator precedence: aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa == (aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa ? b : c); This lead to the discovery that the expression parser incorrectly handled conditional operators and that it could also handle semicolons (which in turn reduced the amount of special casing for for-loops). As a side-effect, we can now apply the bin-packing configuration to the sections of for-loops. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@175973 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-23Remove the hack that avoided mangling static functions in extern C contexts.Rafael Espindola
Weather we should give C language linkage to functions and variables with internal linkage probably depends on how much code assumes it. The standard says they should have no language linkage, but gcc and msvc assign them C language linkage. This commit removes the hack that was preventing the mangling on static functions declare in extern C contexts. It is an experiment to see if we can implement the rules in the standard. If it turns out that many users depend on these functions and variables having C language linkage, we should change isExternC instead and try to convince the CWG to change the standard. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@175937 91177308-0d34-0410-b5e6-96231b3b80d8
