| | | | | | | | | | | | to be considering user-defined conversions in the first place. Doug, please review; I'm not sure what we should be doing if we see a real ambiguity in selecting a copy constructor when otherwise suppressing user-defined conversions. Fixes PR6014. llvm-svn: 93365

* Reimplement constructor declarator parsing to cope with template-idsDouglas Gregor2010-01-138-24/+215
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | that name constructors, the endless joys of out-of-line constructor definitions, and various other corner cases that the previous hack never imagined. Fixes PR5688 and tightens up semantic analysis for constructor names. Additionally, fixed a problem where we wouldn't properly enter the declarator scope of a parenthesized declarator. We were entering the scope, then leaving it when we saw the ")"; now, we re-enter the declarator scope before parsing the parameter list. Note that we are forced to perform some tentative parsing within a class (call it C) to tell the difference between C(int); // constructor and C (f)(int); // member function which is rather unfortunate. And, although it isn't necessary for correctness, we use the same tentative-parsing mechanism for out-of-line constructors to improve diagnostics in icky cases like: C::C C::f(int); // error: C::C refers to the constructor name, but // we complain nicely and recover by treating it as // a type. llvm-svn: 93322
* Record some basic information about bad conversion sequences. Use thatJohn McCall2010-01-134-63/+157

* Improve the reporting of non-viable overload candidates by noting the reasonJohn McCall2010-01-131-44/+107
| | | | | | | | why the candidate is non-viable. There's a lot we can do to improve this, but it's a good start. Further improvements should probably be integrated with the bad-initialization reporting routines. llvm-svn: 93277

This is one of the (few) places where we know for sure that an identifier followed by a '<' must be a template name, so we can diagnose and recover well: test/SemaTemplate/dependent-base-classes.cpp:9:16: error: missing 'template' keyword prior to dependent template name 'T::apply' struct X1 : T::apply<U> { }; // expected-error{{missing 'template' ... ^ template test/SemaTemplate/dependent-base-classes.cpp:12:13: error: unknown template name 'vector' struct X2 : vector<T> { }; // expected-error{{unknown template name 'vector'}} ^ 2 diagnostics generated. llvm-svn: 93257

* Eliminate an embarrassing performance regression in C/ObjC, where weDouglas Gregor2010-01-113-1/+13

Turn off such lookup unless we're in C++ mode, along with the check that determines whether the given identifier is a "current class name", and assert that we don't make this mistake again. llvm-svn: 93207
