| | | | | | | | | <tr1/hashtable> header, where a friend class template std::tr1::__detail::_Map_base is declared with the wrong template parameters. GCC doesn't catch the problem, so Clang does a little back-flip to avoid diagnosing just this one instance of the problem. llvm-svn: 100790

* Eliminate excessive PCH deserialization caused by the search forDouglas Gregor2010-04-083-36/+12
| | | | | | | | | | | | | | | | | | | | | | __cxxabiv1::__fundamental_type_info in every translation unit. Previously, we would perform name lookup for __cxxabiv1::__fundamental_type_info at the end of IRGen for a each translation unit, to determine whether it was present. If so, we we produce type information for all of the fundamental types. However, this name lookup causes PCH deserialization of a significant part of the translation unit, which has a woeful impact on performance. With this change, we now look at each record type after we've generated its vtable to see if it is __cxxabiv1::__fundamental_type_info. If so, we generate type info for all of the fundamental types. This works because __cxxabiv1::__fundamental_type_info should always have a key function (typically the virtual destructor), that will be defined once in the support library. The fundamental type information will end up there. Fixes <rdar://problem/7840011>. llvm-svn: 100772

| | | | | | | | | | | | | | | | | emitting diagnostics after it has produced that many errors. Give this a default value of 20 which produces plenty of errors for people to fix before recompiling but not so many that their entire console scrolls away when the compiler gets confused. The experience looks like this: $ clang foo.c <tons of crap> foo.c:102:3: error: unknown type name 'somethingbad' somethingbad x; ^ fatal error: too many errors emitted, stopping now 36 warnings and 20 errors generated. llvm-svn: 100689

* Instead of counting totally diagnostics, split the count into a countChris Lattner2010-04-072-7/+18
| | | | | | | | | | | | | | | of errors and warnings. This allows us to emit something like this: 2 warnings and 1 error generated. instead of: 3 diagnostics generated. This also stops counting 'notes' because they are just follow-on information about the previous diag, not a diagnostic in themselves. llvm-svn: 100675
* Improve handling of friend types in several ways:Douglas Gregor2010-04-072-64/+63
| | | | | | | | | | | - When instantiating a friend type template, perform semantic analysis on the resulting type. - Downgrade the errors concerning friend type declarations that do not refer to classes to ExtWarns in C++98/03. C++0x allows practically any type to be befriended, and ignores the friend declaration if the type is not a class. llvm-svn: 100635
* Split Sema::ActOnFriendTypeDecl into Sema::CheckFriendTypeDecl (forDouglas Gregor2010-04-072-35/+63
| | | | | | | | semantic analysis) and Sema::ActOnFriendTypeDecl (the action callback). This is a prerequisite for improving template instantiation of friend type declarations. llvm-svn: 100633

This allows us to diagnose invalid inline asms with such nice diagnostics as: <inline asm>:1:2: error: unrecognized instruction abc incl %eax ^ asm.c:2:12: note: generated from here __asm__ ("abc incl %0" : "+r" (X)); ^ 2 diagnostics generated. llvm-svn: 100608

* Implement the protected access restriction ([class.protected]), which requiresJohn McCall2010-04-068-256/+485
| | | | | | | | that protected members be used on objects of types which derive from the naming class of the lookup. My first N attempts at this were poorly-founded, largely because the standard is very badly worded here. llvm-svn: 100562
* When code completion produces an overload set as its results (e.g.,Douglas Gregor2010-04-061-3/+2
