2012-12-11Rename StmtDumper::DumpSubTree() to dumpStmt()Alexander Kornienko
Summary: Also rename DumpDeclarator() to dumpDecl(). Once Decl dumping is added, these will be the two main methods of the class, so this is just for consistency in naming. There was a DumpStmt() method already, but there was no point in having it, so I have merged it into VisitStmt(). Similarly, DumpExpr() is merged into VisitExpr().

2012-12-04Sort all of Clang's files under 'lib', and fix up the broken headersChandler Carruth
uncovered. This required manually correcting all of the incorrect main-module headers I could find, and running the new llvm/utils/sort_includes.py script over the files. I also manually added quite a few missing headers that were uncovered by shuffling the order or moving headers up to be main-module-headers. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@169237 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-30Add info to ObjCPropertyRefExpr to indicate whether the dot syntax propertyArgyrios Kyrtzidis
reference is going to message the setter, the getter, or both. Having this info on the ObjCPropertyRefExpr node makes it easier for AST clients (like libclang) to reason about the meaning of the property reference. [AST/Sema] -Use 2 bits (with a PointerIntPair) in ObjCPropertyRefExpr to record the above info -Have ObjCPropertyOpBuilder set the info appropriately. [libclang] -When there is an implicit property reference (property syntax using methods) have clang_getCursorReferenced return a cursor for the method. If the property reference is going to result in messaging both the getter and the setter choose to return a cursor for the setter because it is less obvious from source inspection that the setter is getting called. The general idea has the seal of approval by John. rdar://11151621 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@153709 91177308-0d34-0410-b5e6-96231b3b80d8

NSNumber, and boolean literals. This includes both Sema and Codegen support. Included is also support for new Objective-C container subscripting. My apologies for the large patch. It was very difficult to break apart. The patch introduces changes to the driver as well to cause clang to link in additional runtime support when needed to support the new language features. Docs are forthcoming to document the implementation and behavior of these features. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@152137 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-22Generate an AST for the conversion from a lambda closure type to aDouglas Gregor
block pointer that returns a block literal which captures (by copy) the lambda closure itself. Some aspects of the block literal are left unspecified, namely the capture variable (which doesn't actually exist) and the body (which will be filled in by IRgen because it can't be written as an AST). Because we're switching to this model, this patch also eliminates tracking the copy-initialization expression for the block capture of the conversion function, since that information is now embedded in the synthesized block literal. -1 side tables FTW. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@151131 91177308-0d34-0410-b5e6-96231b3b80d8

2011-11-06Change the AST representation of operations on Objective-CJohn McCall
property references to use a new PseudoObjectExpr expression which pairs a syntactic form of the expression with a set of semantic expressions implementing it. This should significantly reduce the complexity required elsewhere in the compiler to deal with these kinds of expressions (e.g. IR generation's special l-value kind, the static analyzer's Message abstraction), at the lower cost of specifically dealing with the odd AST structure of these expressions. It should also greatly simplify efforts to implement similar language features in the future, most notably Managed C++'s properties and indexed properties. Most of the effort here is in dealing with the various clients of the AST. I've gone ahead and simplified the ObjC rewriter's use of properties; other clients, like IR-gen and the static analyzer, have all the old complexity *and* all the new complexity, at least temporarily. Many thanks to Ted for writing and advising on the necessary changes to the static analyzer. I've xfailed a small diagnostics regression in the static analyzer at Ted's request. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@143867 91177308-0d34-0410-b5e6-96231b3b80d8

2011-05-01Add an optional field attached to a DeclRefExpr which points back to theChandler Carruth
Decl actually found via name lookup & overload resolution when that Decl is different from the ValueDecl which is actually referenced by the expression. This can be used by AST consumers to correctly attribute references to the spelling location of a using declaration, and otherwise gain insight into the name resolution performed by Clang. The public interface to DRE is kept as narrow as possible: we provide a getFoundDecl() which always returns a NamedDecl, either the ValueDecl referenced or the new, more precise NamedDecl if present. This way AST clients can code against getFoundDecl without know when exactly the AST has a split representation. For an example of the data this provides consider: % cat x.cc namespace N1 { struct S {}; void f(const S&); } void test(N1::S s) { f(s); using N1::f; f(s); } % ./bin/clang -fsyntax-only -Xclang -ast-dump x.cc [...] void test(N1::S s) (CompoundStmt 0x5b02010 <x.cc:5:20, line:9:1> (CallExpr 0x5b01df0 <line:6:3, col:6> 'void' (ImplicitCastExpr 0x5b01dd8 <col:3> 'void (*)(const struct N1::S &)' <FunctionToPointerDecay> (DeclRefExpr 0x5b01d80 <col:3> 'void (const struct N1::S &)' lvalue Function 0x5b01a20 'f' 'void (const struct N1::S &)')) (ImplicitCastExpr 0x5b01e20 <col:5> 'const struct N1::S' lvalue <NoOp> (DeclRefExpr 0x5b01d58 <col:5> 'N1::S':'struct N1::S' lvalue ParmVar 0x5b01b60 's' 'N1::S':'struct N1::S'))) (DeclStmt 0x5b01ee0 <line:7:3, col:14> 0x5b01e40 "UsingN1::;") (CallExpr 0x5b01fc8 <line:8:3, col:6> 'void' (ImplicitCastExpr 0x5b01fb0 <col:3> 'void (*)(const struct N1::S &)' <FunctionToPointerDecay> (DeclRefExpr 0x5b01f80 <col:3> 'void (const struct N1::S &)' lvalue Function 0x5b01a20 'f' 'void (const struct N1::S &)' (UsingShadow 0x5b01ea0 'f'))) (ImplicitCastExpr 0x5b01ff8 <col:5> 'const struct N1::S' lvalue <NoOp> (DeclRefExpr 0x5b01f58 <col:5> 'N1::S':'struct N1::S' lvalue ParmVar 0x5b01b60 's' 'N1::S':'struct N1::S')))) Now we can tell that the second call is 'using' (no pun intended) the using declaration, and *which* using declaration it sees. Without this, we can mistake calls that go through using declarations for ADL calls, and have no way to attribute names looked up with using declarations to the appropriate UsingDecl. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@130670 91177308-0d34-0410-b5e6-96231b3b80d8

2011-02-17Change the representation of GNU ?: expressions to use a different expressionJohn McCall
class and to bind the shared value using OpaqueValueExpr. This fixes an unnoticed problem with deserialization of these expressions where the deserialized form would lose the vital pointer-equality trait; or rather, it fixes it because this patch also does the right thing for deserializing OVEs. Change OVEs to not be a "temporary object" in the sense that copy elision is permitted. This new representation is not totally unawkward to work with, but I think that's really part and parcel with the semantics we're modelling here. In particular, it's much easier to fix things like the copy elision bug and to make the CFG look right. I've tried to update the analyzer to deal with this in at least some obvious cases, and I think we get a much better CFG out, but the printing of OpaqueValueExprs probably needs some work. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@125744 91177308-0d34-0410-b5e6-96231b3b80d8

2011-02-07A few more tweaks to the blocks AST representation: John McCall
- BlockDeclRefExprs always store VarDecls - BDREs no longer store copy expressions - BlockDecls now store a list of captured variables, information about how they're captured, and a copy expression if necessary With that in hand, change IR generation to use the captures data in blocks instead of walking the block independently. Additionally, optimize block layout by emitting fields in descending alignment order, with a heuristic for filling in words when alignment of the end of the block header is insufficient for the most aligned field. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@125005 91177308-0d34-0410-b5e6-96231b3b80d8

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
