2012-08-16Store SourceManager pointer on PrintingPolicy in the case where we're dumping,Richard Smith
and remove ASTContext reference (which was frequently bound to a dereferenced null pointer) from the recursive lump of printPretty functions. In so doing, fix (at least) one case where we intended to use the 'dump' mode, but that failed because a null ASTContext reference had been passed in. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@162011 91177308-0d34-0410-b5e6-96231b3b80d8

2012-08-15[analyzer] If we call a C++ method on an object, assume it's non-null.Jordan Rose
This is analogous to our handling of pointer dereferences: if we dereference a pointer that may or may not be null, we assume it's non-null from then on. While some implementations of C++ (including ours) allow you to call a non-virtual method through a null pointer of object type, it is technically disallowed by the C++ standard, and should not prune out any real paths in practice. [class.mfct.non-static]p1: A non-static member function may be called for an object of its class type, or for an object of a class derived from its class type... (a null pointer value does not refer to an object) We can also make the same assumption about function pointers. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@161992 91177308-0d34-0410-b5e6-96231b3b80d8

2012-08-15[ms-inline asm] MSVC parses multiple __asm statements on a single line as oneChad Rosier
statement. For example, if (x) __asm out dx, ax __asm out dx, ax results in a single inline asm statement (i.e., both "out dx, ax" statements are predicated on if(x)). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@161986 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-15[analyzer] Correctly devirtualize virtual method calls in constructors.Jordan Rose
This is the other half of C++11 [class.cdtor]p4 (the destructor side was added in r161915). This also fixes an issue with post-call checks where the 'this' value was already being cleaned out of the state, thus being omitted from a reconstructed CXXConstructorCall. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@161981 91177308-0d34-0410-b5e6-96231b3b80d8

2012-08-15[analyzer] Only adjust the type of 'this' when we devirtualize a method call.Jordan Rose
With reinterpret_cast, we can get completely unrelated types in a region hierarchy together; this was resulting in CXXBaseObjectRegions being layered directly on an (untyped) SymbolicRegion, whose symbol was from a completely different type hierarchy. This was what was causing the internal buildbot to fail. Reverts r161911, which merely masked the problem. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@161960 91177308-0d34-0410-b5e6-96231b3b80d8

Previously we were checking -analyzer-ipa=dynamic-bifurcate only, and unconditionally inlining everything else that had an available definition, even under -analyzer-ipa=inlining (but not under -analyzer-ipa=none). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@161916 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-15[analyzer] Correctly devirtualize virtual method calls in destructors.Jordan Rose
C++11 [class.cdtor]p4: When a virtual function is called directly or indirectly from a constructor or from a destructor, including during the construction or destruction of the class’s non-static data members, and the object to which the call applies is the object under construction or destruction, the function called is the final overrider in the constructor's or destructor's class and not one overriding it in a more-derived class. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@161915 91177308-0d34-0410-b5e6-96231b3b80d8
