2010-04-30Refactor the AnalysisConsumer to analyze functions after the whole Zhongxing Xu
translation unit is parsed. This enables us to inline some calls when still analyzing one function at a time. Actions are classified into Function, CXXMethod, ObjCMethod, ObjCImplementation. This does not hurt performance much. The analysis time for sqlite3.c: before: real 17m52.440s user 17m49.460s sys 0m2.010s after: real 18m0.500s user 17m56.900s sys 0m2.330s DisplayProgress option is broken now. -inine-call action is removed. It will be reenabled in another form, perhaps as an indenpendant option. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@102689 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-29Teach __builtin_offsetof to compute the offsets of members of baseDouglas Gregor
classes, since we only warn (not error) on offsetof() for non-POD types. We store the base path within the OffsetOfExpr itself, then evaluate the offsets within the constant evaluator. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@102571 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-28Completely reimplement __builtin_offsetof, based on a patch by RobertoDouglas Gregor
Amadini. This change introduces a new expression node type, OffsetOfExpr, that describes __builtin_offsetof. Previously, __builtin_offsetof was implemented using a unary operator whose subexpression involved various synthesized array-subscript and member-reference expressions, which was ugly and made it very hard to instantiate as a template. OffsetOfExpr represents the AST more faithfully, with proper type source information and a more compact representation. OffsetOfExpr also has support for dependent __builtin_offsetof expressions; it can be value-dependent, but will never be type-dependent (like sizeof or alignof). This commit introduces template instantiation for __builtin_offsetof as well. There are two major caveats to this patch: 1) CodeGen cannot handle the case where __builtin_offsetof is not a constant expression, so it produces an error. So, to avoid regressing in C, we retain the old UnaryOperator-based __builtin_offsetof implementation in C while using the shiny new OffsetOfExpr implementation in C++. The old implementation can go away once we have proper CodeGen support for this case, which we expect won't cause much trouble in C++. 2) __builtin_offsetof doesn't work well with non-POD class types, particularly when the designated field is found within a base class. I will address this in a subsequent patch. Fixes PR5880 and a bunch of assertions when building Boost.Python tests. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@102542 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-27Make the InjectedClassNameType the canonical type of the current instantiationJohn McCall
of a class template or class template partial specialization. That is to say, in template <class T> class A { ... }; or template <class T> class B<const T*> { ... }; make 'A<T>' and 'B<const T*>' sugar for the corresponding InjectedClassNameType when written inside the appropriate context. This allows us to track the current instantiation appropriately even inside AST routines. It also allows us to compute a DeclContext for a type much more efficiently, at some extra cost every time we write a template specialization (which can be optimized, but I've left it simple in this patch). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@102407 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-23Improve the AST representation of Objective-C @try/@catch/@finallyDouglas Gregor
statements. Instead of the @try having a single @catch, where all of the @catch's were chained (using an O(n^2) algorithm nonetheless), @try just holds an array of its @catch blocks.

2010-04-21Overhaul the AST representation of Objective-C message sendDouglas Gregor
expressions, to improve source-location information, clarify the actual receiver of the message, and pave the way for proper C++ support. The ObjCMessageExpr node represents four different kinds of message sends in a single AST node: 1) Send to a object instance described by an expression (e.g., [x method:5]) 2) Send to a class described by the class name (e.g., [NSString method:5]) 3) Send to a superclass class (e.g, [super method:5] in class method) 4) Send to a superclass instance (e.g., [super method:5] in instance method) Previously these four cases where tangled together. Now, they have more distinct representations. Specific changes: 1) Unchanged; the object instance is represented by an Expr*. 2) Previously stored the ObjCInterfaceDecl* referring to the class receiving the message. Now stores a TypeSourceInfo* so that we know how the class was spelled. This both maintains typedef information and opens the door for more complicated C++ types (e.g., dependent types). There was an alternative, unused representation of these sends by naming the class via an IdentifierInfo *. In practice, we either had an ObjCInterfaceDecl *, from which we would get the IdentifierInfo *, or we fell into the case below... 3) Previously represented by a class message whose IdentifierInfo * referred to "super". Sema and CodeGen would use isStr("super") to determine if they had a send to super. Now represented as a "class super" send, where we have both the location of the "super" keyword and the ObjCInterfaceDecl* of the superclass we're targetting (statically). 4) Previously represented by an instance message whose receiver is a an ObjCSuperExpr, which Sema and CodeGen would check for via isa<ObjCSuperExpr>(). Now represented as an "instance super" send, where we have both the location of the "super" keyword and the ObjCInterfaceDecl* of the superclass we're targetting (statically). Note that ObjCSuperExpr only has one remaining use in the AST, which is for "super.prop" references. The new representation of ObjCMessageExpr is 2 pointers smaller than the old one, since it combines more storage. It also eliminates a leak when we loaded message-send expressions from a precompiled header. The representation also feels much cleaner to me; comments welcome! This patch attempts to maintain the same semantics we previously had with Objective-C message sends. In several places, there are massive changes that boil down to simply replacing a nested-if structure such as: if (message has a receiver expression) { // instance message if (isa<ObjCSuperExpr>(...)) { // send to super } else { // send to an object } } else { // class message if (name->isStr("super")) { // class send to super } else { // send to class } } with a switch switch (E->getReceiverKind()) { case ObjCMessageExpr::SuperInstance: ... case ObjCMessageExpr::Instance: ... case ObjCMessageExpr::SuperClass: ... case ObjCMessageExpr::Class:... } There are quite a few places (particularly in the checkers) where send-to-super is effectively ignored. I've placed FIXMEs in most of them, and attempted to address send-to-super in a reasonable way. This could use some review. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101972 91177308-0d34-0410-b5e6-96231b3b80d8
