* Some preparatory work for chained PCH. No functionality change.Sebastian Redl2010-07-084-6/+15

* During code completion, give the "nil" and "NULL" macros the sameDouglas Gregor2010-07-081-4/+22
| | | | | | | priority as other constants. And, if we're in a place where we prefer a pointer type, consider "nil" and "NULL" to be close matches. llvm-svn: 107910
* Allow C-style casts and reinterpret_casts between block pointers andDouglas Gregor2010-07-081-7/+29

* PR7588: Fix the _mm_shufflehi_epi16 macro. (The issue was an oversightEli Friedman2010-07-081-3/+4

* Introduce PCHReader::GetTranslationUnitDecl() and use it instead of ↵Argyrios Kyrtzidis2010-07-081-1/+8

* Support TemplateTemplateParmDecl for PCH.Argyrios Kyrtzidis2010-07-082-4/+19

* For TagType and TemplateSpecializationType, isDependent calculation may be ↵Argyrios Kyrtzidis2010-07-082-10/+24
| | | | | | | | | invalid because some decls that the calculation is using may still be initializing. Thus, store the isDependent flag to PCH and restore directly to Type. llvm-svn: 107873
* Read/write the C++ parts of DeclRefExpr and MemberExpr for PCH.Argyrios Kyrtzidis2010-07-083-16/+111

* Add support for differentiating between attributes ignored when handled andChandler Carruth2010-07-081-1/+2
| | | | | | | | unknown attributes that we discard. Add a diagnostic group for unknown attribute warnings to allow turning these off when we don't care. Also consolidates the tests for this case. llvm-svn: 107864

| | | | | | | | typedefs won't have the same canonical declaration (since they are distinct), so we need to check for this case specifically. Fixes <rdar://problem/8018262>. llvm-svn: 107833

* Simplify code and remove comment that is no longer relevant.Argyrios Kyrtzidis2010-07-071-9/+2
| | | | llvm-svn: 107772
* Remove Decl::getCompoundBody().Argyrios Kyrtzidis2010-07-073-6/+2
| | | | | | | | This has 2 (slight) advantages: -Make explicit at getBody()'s callsite that we expect/handle only CompoundStmt and not CXXTryStmt. -Better tracking of Decl::getBody()'s callsites. llvm-svn: 107771

Finds idempotent and/or tautological operations in a path sensitive context, flagging operations that have no effect or a predictable effect. Example: { int a = 1; int b = 5; int c = b / a; // a is 1 on all paths } - New IdempotentOperationChecker class - Moved recursive Stmt functions in r107675 to IdempotentOperationChecker - Minor refactoring of SVal to allow checking for any integer - Added command line option for check - Added basic test cases llvm-svn: 107706
