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. Added dedicated tests for the metafunction. Reviewers: klimek git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@176024 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-25Add matcher for AccessSpecDecls.Daniel Jasper

2013-02-25[analyzer] add the notion of an "interesting" lvalue expression for ↵Ted Kremenek
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
2013-02-24[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

2013-02-22Replace some typically large vectors with SmallVector.Benjamin Kramer
This may seem counter-intuitive but the POD-like optimization helps when the vectors grow into multimegabyte buffers.

commands Add an ability to specify custom documentation block comment commands via a new class CommentOptions.

2013-02-22[analyzer] Place all inlining policy checks into one palceAnna Zaks
Previously, we had the decisions about inlining spread out over multiple functions. In addition to the refactor, this commit ensures that we will always inline BodyFarm functions as long as the Decl is available. This fixes false positives due to those functions not being inlined when no or minimal inlining is enabled such (as shallow mode). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@175857 91177308-0d34-0410-b5e6-96231b3b80d8

to control the check for the C 5.2.4.1 / C++ [implimits] restriction on nesting levels for parentheses, brackets and braces. Some code with heavy macro use exceeds the default limit of 256, but we don't want to increase it generally to avoid stack overflow on stack-constrained systems. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@175855 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-22[analyzer] Make sure a materialized temporary matches its bindings.Jordan Rose
This is a follow-up to r175830, which made sure a temporary object region created for, say, a struct rvalue matched up with the initial bindings being stored into it. This does the same for the case in which the AST actually tells us that we need to create a temporary via a MaterializeObjectExpr. I've unified the two code paths and moved a static helper function onto ExprEngine. This also caused a bit of test churn, causing us to go back to describing temporary regions without a 'const' qualifier. This seems acceptable; it's our behavior from a few months ago. <rdar://problem/13265460> (part 2) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@175854 91177308-0d34-0410-b5e6-96231b3b80d8
