2010-01-25Split libAnalysis into two libraries: libAnalysis and libChecker.Ted Kremenek
(1) libAnalysis is a generic analysis library that can be used by Sema. It defines the CFG, basic dataflow analysis primitives, and inexpensive flow-sensitive analyses (e.g. LiveVariables). (2) libChecker contains the guts of the static analyzer, incuding the path-sensitive analysis engine and domain-specific checks. Now any clients that want to use the frontend to build their own tools don't need to link in the entire static analyzer. This change exposes various obvious cleanups that can be made to the layout of files and headers in libChecker. More changes pending. :) This change also exposed a layering violation between AnalysisContext and MemRegion. BlockInvocationContext shouldn't explicitly know about BlockDataRegions. For now I've removed the BlockDataRegion* from BlockInvocationContext (removing context-sensitivity; although this wasn't used yet). We need to have a better way to extend BlockInvocationContext (and any LocationContext) to add context-sensitivty. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@94406 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-20Unused ivar checker: ivars referenced by lexically nested functions should ↵Ted Kremenek

2009-06-30De-ASTContext-ify DeclContext.Argyrios Kyrtzidis
Remove ASTContext parameter from DeclContext's methods. This change cascaded down to other Decl's methods and changes to call sites started "escalating". Timings using pre-tokenized "cocoa.h" showed only a ~1% increase in time run between and after this commit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74506 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-30Remove the ASTContext parameter from the getBody() methods of Decl and ↵Argyrios Kyrtzidis
subclasses. Timings showed no significant difference before and after the commit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74504 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-30Remove the ASTContext parameter from the attribute-related methods of Decl.Argyrios Kyrtzidis
The implementations of these methods can Use Decl::getASTContext() to get the ASTContext. This commit touches a lot of files since call sites for these methods are everywhere. I used pre-tokenized "carbon.h" and "cocoa.h" headers to do some timings, and there was no real time difference between before the commit and after it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74501 91177308-0d34-0410-b5e6-96231b3b80d8

2009-06-18Move the static DeclAttrs map into ASTContext. Fixes <rdar://problem/6983177>.Douglas Gregor
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@73702 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-23Eliminate the three SmallVectors in ObjCImplDecl (for instanceDouglas Gregor
methods, class methods, and property implementations) and instead place all of these entities into the DeclContext. This eliminates more linear walks when looking for class or instance methods and should make PCH (de-)serialization of ObjCDecls trivial (and lazy). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69849 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-18FunctionDecl::getBody() is getting an ASTContext argument for use inDouglas Gregor
lazy PCH deserialization. Propagate that argument wherever it needs to be. No functionality change, except that I've tightened up a few PCH tests in preparation. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69406 91177308-0d34-0410-b5e6-96231b3b80d8

2008-11-24Rename NamedDecl::getName() to getNameAsString(). Replace a bunch of Chris Lattner
uses of getName() with uses of getDeclName(). This upgrades a bunch of diags to take DeclNames instead of std::strings. This also tweaks a couple of diagnostics to be cleaner and changes CheckInitializerTypes/PerformInitializationByConstructor to pass around DeclarationNames instead of std::strings. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59947 91177308-0d34-0410-b5e6-96231b3b80d8
