2011-08-04Match type names and give more info for out-of-line function definition errors.Kaelyn Uhrain
Having a function declaration and definition with different types for a parameter where the types have same (textual) name can occur when an unqualified type name resolves to types in different namespaces in each location. The error messages have been extended by adding notes that point to the first parameter of the function definition that doesn't match the declaration, instead of a generic "member declaration nearly matches". The generic message is still used in cases where the mismatch is not in the paramenter list, such as mismatched cv qualifiers on the member function itself. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@136891 91177308-0d34-0410-b5e6-96231b3b80d8

2011-08-03Introduce the local -> global declaration ID mapping into the ASTDouglas Gregor
reader, to allow AST files to be loaded with their declarations remapped to different ID numbers. Fix a number of places where we were either failing to map local declaration IDs into global declaration IDs or where interpreting the local declaration IDs within the wrong module. I've tested this via the usual "random gaps" method. It works well except for the preamble tests, because our handling of the precompiled preamble requires declaration and preprocessed entity to be stable when parsing code and then loading that back into memory. This property will hold in general, but my randomized testing naturally breaks this property to get more coverage. In the future, I expect that the precompiled preamble logic won't need this property. I am very unhappy with the current handling of the translation unit, which is a rather egregious hack. We're going to have to do something very different here for loading multiple AST files, because we don't want to have to cope with merging two translation units. Likely, we'll just handle translation units entirely via "update" records, and predefine a single, fixed declaration ID for the translation unit. That will come later. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@136779 91177308-0d34-0410-b5e6-96231b3b80d8

2011-08-03Handle "homogeneous aggregates" as required by the ARM AAPCS-VFP ABI.Bob Wilson
A homogeneous aggregate is an aggregate data structure where after flattening any nesting there are 1 to 4 elements of the same base type that is either a float, double, or Neon vector. All Neon vectors of the same size, either 64 or 128 bits, are treated as equivalent for this purpose. When using the AAPCS-VFP ABI, check for homogeneous aggregates and pass them as arguments by expanding them into a sequence of their base types. This requires extending the existing support for expanded arguments to handle not only structs, but also constant arrays and complex types. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@136767 91177308-0d34-0410-b5e6-96231b3b80d8
