2010-08-07Store inheritance paths after CastExprs instead of inside them.John McCall
This takes some trickery since CastExpr has subclasses (and indeed, is abstract). Also, smoosh the CastKind into the bitfield from Expr. Drops two words of storage from Expr in the common case of expressions which don't need inheritance paths. Avoids a separate allocation and another word of overhead in cases needing inheritance paths. Also has the advantage of not leaking memory, since destructors for AST nodes are never run. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@110507 91177308-0d34-0410-b5e6-96231b3b80d8

2010-06-28Modify the way sub-statements are stored and retrieved from PCH.Argyrios Kyrtzidis
Before this commit, sub-stmts were stored as encountered and when they were placed in the Stmts stack we had to know what index each stmt operand has. This complicated supporting variable sub-stmts and sub-stmts that were contained in TypeSourceInfos, e.g. x = sizeof(int[1]); would crash PCH. Now, sub-stmts are stored in reverse order, from last to first, so that when reading them, in order to get the next sub-stmt we just need to pop the last stmt from the stack. This greatly simplified the way stmts are written and read (just use PCHWriter::AddStmt and PCHReader::ReadStmt accordingly) and allowed variable stmt operands and TypeSourceInfo exprs. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@107087 91177308-0d34-0410-b5e6-96231b3b80d8

2010-05-15Implement semantic analysis and an AST representation for the namedDouglas Gregor
return value optimization. Sema marks return statements with their NRVO candidates (which may or may not end up using the NRVO), then, at the end of a function body, computes and marks those variables that can be allocated into the return slot. I've checked this locally with some debugging statements (not committed), but there won't be any tests until CodeGen comes along. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@103865 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
2010-04-23Improve 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. The resulting AST is slightly more compact (not important) and better represents the actual language semantics (good). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@102221 91177308-0d34-0410-b5e6-96231b3b80d8
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
