2012-02-10Track whether a function type has a trailing return type as type sugar. Use thisRichard Smith
to pretty-print such function types better, and to fix a case where we were not instantiating templates in lexical order. In passing, move the Variadic bit from Type's bitfields to FunctionProtoType to get the Type bitfields down to 32 bits. Also ensure that we always substitute the return type of a function when substituting explicitly-specified arguments, since that can cause us to bail out with a SFINAE error before we hit a hard error in parameter substitution. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@150241 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-08Revise the SplitQualType interface to make it its own thing instead ofJohn McCall
a typedef of std::pair. This slightly improves type-safety, but mostly makes code using it clearer to read as well as making it possible to add methods to the type. Add such a method for efficiently single-step desugaring a split type. Add a method to single-step desugaring a locally-unqualified type. Implement both the SplitQualType and QualType methods in terms of that. Also, fix a typo ("ObjCGLifetime"). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@150028 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-07Revert my patches which removed Diagnostic.h includes by moving some ↵Benjamin Kramer
operator overloads out of line. This seems to negatively affect compile time onsome ObjC tests (which use a lot of partial diagnostics I assume). I have to come up with a way to keep them inline without including Diagnostic.h everywhere. Now adding a new diagnostic requires a full rebuild of e.g. the static analyzer which doesn't even use those diagnostics. This reverts commit 6496bd10dc3a6d5e3266348f08b6e35f8184bc99.

2012-01-14De-virtualize getPreviousDecl() and getMostRecentDecl() when we knowDouglas Gregor
we have a redeclarable type, and only use the new virtual versions (getPreviousDeclImpl() and getMostRecentDeclImpl()) when we don't have that type information. This keeps us from penalizing users with strict type information (and is the moral equivalent of a "final" method). Plus, settle on the names getPreviousDecl() and getMostRecentDecl() throughout. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@148187 91177308-0d34-0410-b5e6-96231b3b80d8

2011-11-30Add bigger method type encodings to protocol objects. <rdar://problem/10492418>Bob Wilson
The new metadata are method @encode strings with additional data. 1. Each Objective-C object is marked with its class name and protocol names. The same is done for property @encode already. 2. Each block object is marked with its function prototype's @encoding. For example, a method parameter that is a block object that itself returns void and takes an int would look like: @?<v@?i> These new method @encode strings are stored in a single array pointed to by structs protocol_t and objc_protocol_ext.
