2010-12-23Change all self assignments X=X to (void)X, so that we can turn on aJeffrey Yasskin
new gcc warning that complains on self-assignments and self-initializations. Fix one bug found by the warning, in which one clang::OverloadCandidate constructor failed to initialize its FunctionTemplate member. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@122459 91177308-0d34-0410-b5e6-96231b3b80d8

2010-12-22Unify the consistency checking for deduced template arguments into aDouglas Gregor

2010-12-22Implement template argument deduction for pack expansions whoseDouglas Gregor
pattern is a template argument, which involves repeatedly deducing template arguments using the pattern of the pack expansion, then bundling the resulting deductions into an argument pack. We can now handle a variety of simple list-handling metaprograms using variadic templates. See, e.g., the new "count" metaprogram. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@122439 91177308-0d34-0410-b5e6-96231b3b80d8

2010-12-22When performing template argument deduction where the argument is aDouglas Gregor
dependent template specialization type, the number of template arguments need not match precisely. Rather than checking the number of arguments eagerly (which does not consider argument packs), let the deduction routine for template argument lists cope with too many/too few arguments. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@122425 91177308-0d34-0410-b5e6-96231b3b80d8

2010-12-22Implicitly expand argument packs when performing template argumentDouglas Gregor
deduction. Unify all of the looping over template arguments for deduction purposes into a single place, where argument pack expansion occurs; this is also the hook for deducing from pack expansions, which itself is not yet implemented. For now, at least we can handle a basic "count" metafunction written with variadics. See the new test for the formulation that works. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@122418 91177308-0d34-0410-b5e6-96231b3b80d8

2010-12-22After inlining the CXXConstructExpr, bind the temporary object region to it.Zhongxing Xu
This change is necessary when the variable is a const reference and we need the l-value of the construct expr. After that, when binding the variable, recover the lazy compound value when the variable is not a reference. In Environment, use the value of a no-op cast expression when it has one. Otherwise, blast-through it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@122388 91177308-0d34-0410-b5e6-96231b3b80d8
2010-12-22Redesign the way anonymous fields are handled in designated-initializers.Francois Pichet
Previously designated anonymous fields were found via name lookup. This redesign uses the fact that an IndirectFieldDecl declaration will always follow an anonymous implicit field to remove the special case of name lookup. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@122387 91177308-0d34-0410-b5e6-96231b3b80d8

2010-12-21In C++, if the user redeclares a builtin function with a type that isDouglas Gregor
inconsistent with the type that the builtin *should* have, forget about the builtin altogether: we don't want subsequence analyses, CodeGen, etc., to think that we have a proper builtin function. C is protected from errors here because it allows one to use a library builtin without having a declaration, and detects inconsistent (re-)declarations of builtins during declaration merging. C++ was unprotected, and therefore would crash. Fixes PR8839. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@122351 91177308-0d34-0410-b5e6-96231b3b80d8
2010-12-21Fix a major inconsistency in the representation of Objective-CDouglas Gregor
classes, categories, protocols, and class extensions, where the methods and properties of these entities would be inserted into the DeclContext in an ordering that doesn't necessarily reflect source order. The culprits were Sema::ActOnMethodDeclaration(), which did not perform the insertion of the just-created method declaration into the DeclContext for these Objective-C entities, and Sema::ActOnAtEnd(), which inserted all method declarations at the *end* of the DeclContext. With this fix in hand, clean up the code-completion actions for property setters/getters that worked around this brokenness in the AST. Fixes <rdar://problem/8062781>, where this problem manifested as poor token-annotation information, but this would have struck again in many other places. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@122347 91177308-0d34-0410-b5e6-96231b3b80d8

2010-12-20Extend the parser to support pack expansions within exceptionDouglas Gregor

2010-12-20Further refactoring of the tree transformation for template argumentDouglas Gregor
lists, so that all such transformations go through a single, iterator-based transformation function. This is the only place where we need to implement the logic for transforming pack expansions whose pattern is a template argument. Unfortunately, the new cases this refactoring brings into the fold can't be meaningfully tested yet. We need template argument deduction to work well enough for variadic function templates first. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@122289 91177308-0d34-0410-b5e6-96231b3b80d8
2010-12-20Give the RecursiveASTVisitor a configuration functionDouglas Gregor
shouldWalkTypesOfTypeLocs() that determines whether it should walk the Types within TypeLocs. This walk is redundant, but perhaps required for some clients. Disabling this redundant walk in the unexpanded parameter pack finder produces better results, because we get parameter packs with source location info *unless* such source location information isn't available. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@122287 91177308-0d34-0410-b5e6-96231b3b80d8

2010-12-20Implement basic support for template instantiation of pack expansionsDouglas Gregor
whose patterns are template arguments. We can now instantiate, e.g., typedef tuple<pair<OuterTypes, InnerTypes>...> type; where OuterTypes and InnerTypes are template type parameter packs. There is a horrible inefficiency in TemplateArgumentLoc::getPackExpansionPattern(), where we need to create copies of TypeLoc data because our interfaces traffic in TypeSourceInfo pointers where they should traffic in TypeLocs instead. I've isolated in efficiency in this one routine; once we refactor our interfaces to traffic in TypeLocs, we can eliminate it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@122278 91177308-0d34-0410-b5e6-96231b3b80d8
