headers. Future approaches to (de-)serializing ASTs will be based on the PCH infrastructure. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69828 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-28Change compound assignment operators to keep track of both the promoted Eli Friedman
LHS type and the computation result type; this encodes information into the AST which is otherwise non-obvious. Fix Sema to always come up with the right answer for both of these types. Fix IRGen and the analyzer to account for these changes. This fixes PR2601. The approach is inspired by PR2601 comment 2. Note that this changes real *= complex in CodeGen from a silent miscompilation to an explicit error. I'm not really sure that the analyzer changes are correct, or how to test them... someone more familiar with the analyzer should check those changes. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@67889 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-19Generalize printing of nested-name-specifier sequences for use in bothDouglas Gregor
QualifiedNameType and QualifiedDeclRefExpr. We now keep track of the exact nested-name-specifier spelling for a QualifiedDeclRefExpr, and use that spelling when printing ASTs. This fixes PR3493. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@67283 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-13Implement template instantiation for several more kinds of expressions:Douglas Gregor
- C++ function casts, e.g., T(foo) - sizeof(), alignof() More importantly, this allows us to verify that we're performing overload resolution during template instantiation, with argument-dependent lookup and the "cached" results of name lookup from the template definition. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66947 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-04Change Parser::ParseCaseStatement to use an iterative approach to parsingChris Lattner
multiple sequential case statements instead of doing it with recursion. This fixes a problem where we run out of stack space parsing 100K directly nested cases. There are a couple other problems that prevent this from being useful in practice (right now the example only parses correctly with -disable-free and doesn't work with -emit-llvm), but this is a start. I'm not including a testcase because it is large and uninteresting for regtesting. Sebastian, I would appreciate it if you could scrutinize the smart pointer gymnastics I do. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66011 91177308-0d34-0410-b5e6-96231b3b80d8

the various PPTokens that are pasted together to make it. In the course of working on this, I discovered ParseObjCStringLiteral which needs some work. I'll tackle it next. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64892 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-13Remove DeclGroupOwningRef, since we intend for declarations to be ownedDouglas Gregor
by DeclContexts (always) rather than by statements. DeclContext currently goes out of its way to avoid destroying any Decls that might be owned by a DeclGroupOwningRef. However, in an error-recovery situation, a failure in a declaration statement can cause all of the decls in a DeclGroupOwningRef to be destroyed after they've already be added into the DeclContext. Hence, DeclContext is left with already-destroyed declarations, and bad things happen. This problem was causing failures that showed up as assertions on x86 Linux in test/Parser/objc-forcollection-neg-2.m. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64474 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-07Overhaul of Stmt allocation:Ted Kremenek
- Made allocation of Stmt objects using vanilla new/delete a *compiler error* by making this new/delete "protected" within class Stmt. - Now the only way to allocate Stmt objects is by using the new operator that takes ASTContext& as an argument. This ensures that all Stmt nodes are allocated from the same (pool) allocator. - Naturally, these two changes required that *all* creation sites for AST nodes use new (ASTContext&). This is a large patch, but the majority of the changes are just this mechanical adjustment. - The above changes also mean that AST nodes can no longer be deallocated using 'delete'. Instead, one most do StmtObject->Destroy(ASTContext&) or do ASTContextObject.Deallocate(StmtObject) (the latter not running the 'Destroy' method). Along the way I also... - Made CompoundStmt allocate its array of Stmt* using the allocator in ASTContext (previously it used std::vector). There are a whole bunch of other Stmt classes that need to be similarly changed to ensure that all memory allocated for ASTs comes from the allocator in ASTContext. - Added a new smart pointer ExprOwningPtr to Sema.h. This replaces the uses of llvm::OwningPtr within Sema, as llvm::OwningPtr used 'delete' to free memory instead of a Stmt's 'Destroy' method. Big thanks to Doug Gregor for helping with the acrobatics of making 'new/delete' private and the new smart pointer ExprOwningPtr! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63997 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-06Move StringLiteral to allocate its internal string data using the allocator inTed Kremenek
ASTContext. This required changing all clients to pass in the ASTContext& to the constructor of StringLiteral. I also changed all allocations of StringLiteral to use new(ASTContext&). Along the way, I updated a bunch of new()'s in StmtSerialization.cpp to use the allocator from ASTContext& (not complete). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63958 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-04Fix our semantic analysis ofDouglas Gregor
unqualified-id '(' in C++. The unqualified-id might not refer to any declaration in our current scope, but declarations by that name might be found via argument-dependent lookup. We now do so properly. As part of this change, CXXDependentNameExpr, which was previously designed to express the unqualified-id in the above constructor within templates, has become UnresolvedFunctionNameExpr, which does effectively the same thing but will work for both templates and non-templates. Additionally, we cope with all unqualified-ids, since ADL also applies in cases like operator+(x, y) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63733 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-20Remove ScopedDecl, collapsing all of its functionality into Decl, soDouglas Gregor
that every declaration lives inside a DeclContext. Moved several things that don't have names but were ScopedDecls (and, therefore, NamedDecls) to inherit from Decl rather than NamedDecl, including ObjCImplementationDecl and LinkageSpecDecl. Now, we don't store empty DeclarationNames for these things, nor do we try to insert them into DeclContext's lookup structure. The serialization tests are temporarily disabled. We'll re-enable them once we've sorted out the remaining ownership/serialiazation issues between DeclContexts and TranslationUnion, DeclGroups, etc. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62562 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-16Part one of handling C++ functional casts. This handles semanticDouglas Gregor
analysis and AST-building for the cases where we have N != 1 arguments. For N == 1 arguments, we need to finish the C++ implementation of explicit type casts (C++ [expr.cast]). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62329 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-06Add QualifiedDeclRefExpr, which retains additional source-locationDouglas Gregor
information for declarations that were referenced via a qualified-id, e.g., N::C::value. We keep track of the location of the start of the nested-name-specifier. Note that the difference between QualifiedDeclRefExpr and DeclRefExpr does have an effect on the semantics of function calls in two ways: 1) The use of a qualified-id instead of an unqualified-id suppresses argument-dependent lookup 2) If the name refers to a virtual function, the qualified-id version will call the function determined statically while the unqualified-id version will call the function determined dynamically (by looking up the appropriate function in the vtable). Neither of these features is implemented yet, but we do print out qualified names for QualifiedDeclRefExprs as part of the AST printing. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@61789 91177308-0d34-0410-b5e6-96231b3b80d8

Implement most of the parsing job for the G++ type traits extension. Fully implement the low-hanging fruit of the type traits: __is_pod: Whether a type is a POD. __is_class: Whether a type is a (non-union) class. __is_union: Whether a type is a union. __is_enum: Whether a type is an enum. __is_polymorphic: Whether a type is polymorphic (C++ [class.virtual]p1). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@61746 91177308-0d34-0410-b5e6-96231b3b80d8

2008-12-06Add support for calls to dependent names within templates, e.g.,Douglas Gregor
template<typename T> void f(T x) { g(x); // g is a dependent name, so don't even bother to look it up g(); // error: g is not a dependent name } Note that when we see "g(", we build a CXXDependentNameExpr. However, if none of the call arguments are type-dependent, we will force the resolution of the name "g" and replace the CXXDependentNameExpr with its result. GCC actually produces a nice error message when you make this mistake, and even offers to compile your code with -fpermissive. I'll do the former next, but I don't plan to do the latter. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@60618 91177308-0d34-0410-b5e6-96231b3b80d8
2008-12-04Several things...Steve Naroff
- Implement RewritePropertySetter(). While the routine is simple, there were some tricky changes to RewriteFunctionBodyOrGlobalInitializer(), the main rewriter loop. It also required some additional instance data to distinguish setters from getters, as well as some changes to RewritePropertyGetter(). - Implement FIXME: for pretty printing ObjCPropertyRefExpr's. - Changed ObjCPropertyRefExpr::getSourceRange() to point to the end of the property name (not the beginning). Also made a minor name change from "Loc"->"IdLoc" (to make it clear the Loc does not point to the "."). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@60540 91177308-0d34-0410-b5e6-96231b3b80d8

2008-11-14Add a new expression node, CXXOperatorCallExpr, which expresses aDouglas Gregor
function call created in response to the use of operator syntax that resolves to an overloaded operator in C++, e.g., "str1 + str2" that resolves to std::operator+(str1, str2)". We now build a CXXOperatorCallExpr in C++ when we pick an overloaded operator. (But only for binary operators, where we actually implement overloading) I decided *not* to refactor the current CallExpr to make it abstract (with FunctionCallExpr and CXXOperatorCallExpr as derived classes). Doing so would allow us to make CXXOperatorCallExpr a little bit smaller, at the cost of making the argument and callee accessors virtual. We won't know if this is going to be a win until we can parse lots of C++ code to determine how much memory we'll save by making this change vs. the performance penalty due to the extra virtual calls. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59306 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-12Implement support for operator overloading using candidate operatorDouglas Gregor
functions for built-in operators, e.g., the builtin bool operator==(int const*, int const*) can be used for the expression "x1 == x2" given: struct X { operator int const*(); } x1, x2; The scheme for handling these built-in operators is relatively simple: for each candidate required by the standard, create a special kind of candidate function for the built-in. If overload resolution picks the built-in operator, we perform the appropriate conversions on the arguments and then let the normal built-in operator take care of it. There may be some optimization opportunity left: if we can reduce the number of built-in operator overloads we generate, overload resolution for these cases will go faster. However, one must be careful when doing this: GCC generates too few operator overloads in our little test program, and fails to compile it because none of the overloads it generates match. Note that we only support operator overload for non-member binary operators at the moment. The other operators will follow. As part of this change, ImplicitCastExpr can now be an lvalue. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59148 91177308-0d34-0410-b5e6-96231b3b80d8

2008-10-27Refactor the expression class hierarchy for casts. Most importantly:Douglas Gregor
- CastExpr is the root of all casts - ImplicitCastExpr is (still) used for all explicit casts - ExplicitCastExpr is now the root of all *explicit* casts - ExplicitCCastExpr (new name needed!?) is a C-style cast in C or C++ - CXXFunctionalCastExpr inherits from ExplicitCastExpr - CXXNamedCastExpr inherits from ExplicitCastExpr and is the root of all of the C++ named cast expression types (static_cast, dynamic_cast, etc.) - Added classes CXXStaticCastExpr, CXXDynamicCastExpr, CXXReinterpretCastExpr, and CXXConstCastExpr to Also, fixed returned-stack-addr.cpp, which broke once when we fixed reinterpret_cast to diagnose double->int* conversions and again when we eliminated implicit conversions to reference types. The fix is in both testcase and SemaChecking.cpp. Most of this patch is simply support for the renaming. There's very little actual change in semantics. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@58264 91177308-0d34-0410-b5e6-96231b3b80d8
