2009-08-11Refactor the template-instantiation logic for expressions into aDouglas Gregor
generic tree transformation (also used for recanonicalization) and a small amount of template-instantiation-specific logic. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@78645 91177308-0d34-0410-b5e6-96231b3b80d8

Fixes PR4704 problems Addresses Eli's patch feedback re: ugly cast code Updates all postfix operators to remove ParenListExprs.

2009-08-09AltiVec-style vector initializer syntax, vec4 a = (vec4)(a, b, c, d);Nate Begeman
In addition to being defined by the AltiVec PIM, this is also the vector initializer syntax used by OpenCL, so that vector literals are compatible with macro arguments. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@78535 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-29[llvm up]Douglas Gregor
A template name can refer to a set of overloaded function templates. Model this in TemplateName, which can now refer to an OverloadedFunctionDecl that contains function templates. This removes an unspeakable hack in Sema::isTemplateName. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@77488 91177308-0d34-0410-b5e6-96231b3b80d8

templates, such as make<int&>. These template-ids are only barely functional for function calls; much more to come. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74563 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-30Refactor ActOnDeclarationNameExpr into a "parsing action" part and aDouglas Gregor
"semantic analysis" part. Use the "semantic analysis" part when performing template instantiation on a DeclRefExpr, rather than an ad hoc list of rules to construct DeclRefExprs from the instantiation. A test case for this change will come in with a large commit, which illustrates what I was actually trying to work on. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74528 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-30De-ASTContext-ify DeclContext.Argyrios Kyrtzidis
Remove ASTContext parameter from DeclContext's methods. This change cascaded down to other Decl's methods and changes to call sites started "escalating".

2009-06-25Improved semantic analysis and AST respresentation for functionDouglas Gregor
templates. For example, this now type-checks (but does not instantiate the body of deref<int>): template<typename T> T& deref(T* t) { return *t; } void test(int *ip) { int &ir = deref(ip); } Specific changes/additions: * Template argument deduction from a call to a function template. * Instantiation of a function template specializations (just the declarations) from the template arguments deduced from a call. * FunctionTemplateDecls are stored directly in declaration contexts and found via name lookup (all forms), rather than finding the FunctionDecl and then realizing it is a template. This is responsible for most of the churn, since some of the core declaration matching and lookup code assumes that all functions are FunctionDecls. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74213 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-22Rework the way we track which declarations are "used" duringDouglas Gregor
compilation, and (hopefully) introduce RAII objects for changing the "potentially evaluated" state at all of the necessary places within Sema and Parser. Other changes: - Set the unevaluated/potentially-evaluated context appropriately during template instantiation. - We now recognize three different states while parsing or instantiating expressions: unevaluated, potentially evaluated, and potentially potentially evaluated (for C++'s typeid). - When we're in a potentially potentially-evaluated context, queue up MarkDeclarationReferenced calls in a stack. For C++ typeid expressions that are potentially evaluated, we will play back these MarkDeclarationReferenced calls when we exit the corresponding potentially potentially-evaluated context. - Non-type template arguments are now parsed as constant expressions, so they are not potentially-evaluated. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@73899 91177308-0d34-0410-b5e6-96231b3b80d8

2009-06-05Several improvements to template argument deduction:Douglas Gregor
- Once we have deduced template arguments for a class template partial specialization, we use exactly those template arguments for instantiating the definition of the class template partial specialization. - Added template argument deduction for non-type template parameters. - Added template argument deduction for dependently-sized array types. With these changes, we can now implement, e.g., the remove_reference type trait. Also, Daniel's Ackermann template metaprogram now compiles properly. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72909 91177308-0d34-0410-b5e6-96231b3b80d8

2009-05-29Reduce the amount of stack space we use in SmallVectors duringDouglas Gregor
template instantiation. This helps reduce our stack footprint when performing deep template instantiations. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72582 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-27Simplify, and improve the performance of, template instantiation forDouglas Gregor
declaration references. The key realization is that dependent Decls, which actually require instantiation, can only refer to the current instantiation or members thereof. And, since the current context during instantiation contains all of those members of the current instantiation, we can simply find the real instantiate that matches up with the "current instantiation" template. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72486 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-27Improve name lookup for and template instantiation of declarationDouglas Gregor
references. There are several smallish fixes here: - Make sure we look through template parameter scope when determining whether we're parsing a nested class (or nested class *template*). This makes sure that we delay parsing the bodies of inline member functions until after we're out of the outermost class (template) scope. - Since the bodies of member functions are always parsed "out-of-line", even when they were declared in-line, teach unqualified name lookup to look into the (semantic) parents. - Use the new InstantiateDeclRef to handle the instantiation of a reference to a declaration (in DeclRefExpr), which drastically simplifies template instantiation for DeclRefExprs. - When we're instantiating a ParmVarDecl, it must be in the current instantiation scope, so only look there. Also, remove the #if 0's and FIXME's from the dynarray example, which now compiles and executes thanks to Anders and Eli. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72481 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-27Initial stab at a generalized operation for determining theDouglas Gregor
instantiation of a declaration from the template version (or version that lives in a template) and a given set of template arguments. This needs much, much more testing, but it suffices for simple examples like typedef T* iterator; iterator begin(); git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72461 91177308-0d34-0410-b5e6-96231b3b80d8

2009-05-22Template instantiation for qualified declaration referenceDouglas Gregor
expressions. We are now missing template instantiation logic for only three classes of expressions: - Blocks-related expressions (BlockExpr, BlockDeclRefExpr) - C++ default argument expressions - Objective-C expressions Additionally, our handling of DeclRefExpr is still quite poor, since it cannot handle references to many kinds of declarations. As part of this change, converted the TemplateExprInstantiator to use iteration through all of the expressions via clang/AST/StmtNodes.def, ensuring that we don't forget to add template instantiation logic for any new expression node kinds. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72303 91177308-0d34-0410-b5e6-96231b3b80d8

2009-05-22Representation of and template instantiation for memberDouglas Gregor
expressions. This change introduces another AST node, CXXUnresolvedMemberExpr, that captures member references (x->m, x.m) when the base of the expression (the "x") is type-dependent, and we therefore cannot resolve the member reference yet. Note that our parsing of member references for C++ is still quite poor, e.g., we don't handle x->Base::m or x->operator int. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72281 91177308-0d34-0410-b5e6-96231b3b80d8
