2010-05-09pchify CXXMemberCallExpr correctly. Before it would serializeChris Lattner
and deserialize as a CallExpr which is close, but ends up deserializing with the wrong stmt class. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@103371 91177308-0d34-0410-b5e6-96231b3b80d8

2010-05-08Fix a silly bootstrap-breaking thinko, where we were trying to convertDouglas Gregor
non-existent condition expressions to boolean values during template instantiation. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@103364 91177308-0d34-0410-b5e6-96231b3b80d8

2010-05-08Improve our handling of the -Wunused-variable warning in templates. InDouglas Gregor
particular, don't complain about unused variables that have dependent type until instantiation time, so that we can look at the type of the variable. Moreover, only complain about unused variables that have neither a user-declared constructor nor a non-trivial destructor. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@103362 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-08Don't complain about an __builtin_va_arg expression's result beingDouglas Gregor

2010-05-08Add a SizeOfLargestEmptySubobject member to ASTRecordLayout. For C++ classes ↵Anders Carlsson
this will hold the largest empty subobject or 0 if the class doesn't have any empty subobjects. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@103359 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-08When instantiating statements that involve conditions (if, while, do,Douglas Gregor
for, and switch), be careful to construct the full expressions as soon as we perform template instantation, so we don't either forget to call temporary destructors or destroy temporaries at the wrong time. This is the template-instantiation analogue to r103187, during which I hadn't realized that the issue would affect the handling of these constructs differently inside and outside of templates. Fixes a regression in Boost.Function. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@103357 91177308-0d34-0410-b5e6-96231b3b80d8

2010-05-08When printing a non-viable overload candidate that failed due toDouglas Gregor
conflicting deduced template argument values, give a more specific reason along with those values, e.g., test/SemaTemplate/overload-candidates.cpp:4:10: note: candidate template ignored: deduced conflicting types for parameter 'T' ('int' vs. 'long') const T& min(const T&, const T&); ^ git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@103339 91177308-0d34-0410-b5e6-96231b3b80d8

2010-05-07If there is not any debug info for type then do not emit debug info for this ↵Devang Patel

2010-05-07The FP constant evaluator was missing a few cases of unary operators that ↵John McCall

2010-05-07Reapply the reference-binding patch applied below, along with a fix toDouglas Gregor
ensure that we complete the type when we need to look at constructors during reference binding. When determining whether the two types involved in reference binding are reference-compatible, reference-related, etc., do not complete the type of the reference itself because it is not necessary to determine well-formedness of the program. Complete the type that we are binding to, since that can affect whether we know about a derived-to-base conversion.

2010-05-07reimplement the guts of SourceManager::isBeforeInTranslationUnitChris Lattner
to be algorithmically faster and avoid an std::map. This routine basically boils down to finding the nearest common ancestor in a tree, and we (implicitly) have information about nesting depth, use it!

2010-05-07reimplement the caching in the SourceManager::isBeforeInTranslationUnit()Chris Lattner
