2010-11-10Instantiate class member template partial specialization declarationsDouglas Gregor
in the order they occur within the class template, delaying out-of-line member template partial specializations until after the class has been fully instantiated. This fixes a regression introduced by r118454 (itself a fix for PR8001). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@118704 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-10Region-allocate all AttributeList objects from a factory object instead of ↵Ted Kremenek
manually managing them using new/delete and OwningPtrs. After memory profiling Clang, I witnessed periodic leaks of these objects; digging deeper into the code, it was clear that our management of these objects was a mess. The ownership rules were murky at best, and not always followed. Worse, there are plenty of error paths where we could screw up. This patch introduces AttributeList::Factory, which is a factory class that creates AttributeList objects and then blows them away all at once. While conceptually simple, most of the changes in this patch just have to do with migrating over to the new interface. Most of the changes have resulted in some nice simplifications. This new strategy currently holds on to all AttributeList objects during the lifetime of the Parser object. This is easily tunable. If we desire to have more bound the lifetime of AttributeList objects more precisely, we can have the AttributeList::Factory object (in Parser) push/pop its underlying allocator as we enter/leave key methods in the Parser. This means that we get simple memory management while still having the ability to finely control memory use if necessary. Note that because AttributeList objects are now BumpPtrAllocated, we may reduce malloc() traffic in many large files with attributes. This fixes the leak reported in: <rdar://problem/8650003> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@118675 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-07Remove broken support for variadic templates, along with the variousDouglas Gregor
abstractions (e.g., TemplateArgumentListBuilder) that were designed to support variadic templates. Only a few remnants of variadic templates remain, in the parser (parsing template type parameter packs), AST (template type parameter pack bits and TemplateArgument::Pack), and Sema; these are expected to be used in a future implementation of variadic templates. But don't get too excited about that happening now. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@118385 91177308-0d34-0410-b5e6-96231b3b80d8

2010-10-25Improve the tracking of source locations for parentheses in constructor calls.Chandler Carruth
This adds them where missing, and traces them through PCH. We fix at least one bug in the extents found by the Index library, and make a lot of refactoring tools which care about the exact formulation of a constructor call easier to write. Also some minor cleanups to more consistently follow the friend pattern instead of the setter pattern when rebuilding a serialized AST. Patch originally by Samuel Benzaquen. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@117254 91177308-0d34-0410-b5e6-96231b3b80d8

2010-10-22When we perform name lookup for a template, we may end up finding anDouglas Gregor

2010-10-19Tweak code-completion result priorities, so that exact and similarDouglas Gregor
type matches have a bigger impact. The impetus for this change was that, when initializing an enumeration value, we want enumerators of that enumeration type to have a higher priority than, e.g., unrelated local variables. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116774 91177308-0d34-0410-b5e6-96231b3b80d8

2010-10-12Introduce support for emitting diagnostics (warnings + their notes)Douglas Gregor
that are suppressed during template argument deduction. This change queues diagnostics computed during template argument deduction. Then, if the resulting function template specialization or partial specialization is chosen by overload resolution or partial ordering (respectively), we will emit the queued diagnostics at that point. This addresses most of PR6784. However, the check for unnamed/local template arguments (which existed before this change) is still only skin-deep, and needs to be extended to look deeper into types. It must be improved to finish PR6784. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116373 91177308-0d34-0410-b5e6-96231b3b80d8
