2012-03-09Improve our semantic error recovery.Argyrios Kyrtzidis
When an error made a record member invalid, the record would stay as "isBeingDefined" and not "completeDefinition". Even easily recoverable errors ended up propagating records in such "beingDefined" state, for example: struct A { ~A() const; // expected-error {{'const' qualifier is not allowed on a destructor}} }; struct B : A {}; // A & B would stay as "not complete definition" and "being defined". This weird state was impending lookups in the records and hitting assertion in the ASTWriter.

starting with an underscore is ill-formed. Since this rule rejects programs that were using <inttypes.h>'s macros, recover from this error by treating the ud-suffix as a separate preprocessing-token, with a DefaultError ExtWarn. The approach of treating such cases as two tokens is under discussion for standardization, but is in any case a conforming extension and allows existing codebases to keep building while the committee makes up its mind. Reword the warning on the definition of literal operators not starting with underscores (which are, strangely, legal) to more explicitly state that such operators can't be called by literals. Remove the special-case diagnostic for hexfloats, since it was both triggering in the wrong cases and incorrect. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@152287 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-07AST representation for user-defined literals, plus just enough of semanticRichard Smith
analysis to make the AST representation testable. They are represented by a new UserDefinedLiteral AST node, which is a sugared CallExpr. All semantic properties, including full CodeGen support, are achieved for free by this representation. UserDefinedLiterals can never be dependent, so no custom instantiation behavior is required. They are mangled as if they were direct calls to the underlying literal operator. This matches g++'s apparent behavior (but not its actual mangling, which is broken for literal-operator-ids). User-defined *string* literals are now fully-operational, but the semantic analysis is quite hacky and needs more work. No other forms of user-defined literal are created yet, but the AST support for them is present. This patch committed after midnight because we had already hit the quota for new kinds of literal yesterday. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@152211 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-07Refactor Clang sema attribute handling.Michael Han
This submission improves Clang sema handling by using Clang tablegen to generate common boilerplate code. As a start, it implements AttributeList enumerator generation and case statements for AttributeList::getKind. A new field "SemaHandler" is introduced in Attr.td and by default set to 1 as most of attributes in Attr.td have semantic checking in Sema. For a small number of attributes that don't appear in Sema, the value is set to 0. Also there are a small number of attributes that only appear in Sema but not in Attr.td. Currently these attributes are still hardcoded in Sema AttributeList.

In the included testcase, soma thinks that we already have a definition after we see the out of line decl. Codegen puts it in a deferred list, to be output if a use is seen.
