Add serialization for captured statements and captured decls. Also add a const_capture_iterator to CapturedStmt.

2013-04-17Extended VerifyDiagnosticConsumer to also verify source file for diagnostic.Andy Gibbs
VerifyDiagnosticConsumer previously would not check that the diagnostic and its matching directive referenced the same source file. Common practice was to create directives that referenced other files but only by line number, and this led to problems such as when the file containing the directive didn't have enough lines to match the location of the diagnostic in the other file, leading to bizarre file formatting and other oddities. This patch causes VerifyDiagnosticConsumer to match source files as well as line numbers. Therefore, a new syntax is made available for directives, for example: // expected-error@file:line {{diagnostic message}} This extends the @line feature where "file" is the file where the diagnostic is generated. The @line syntax is still available and uses the current file for the diagnostic. "file" can be specified either as a relative or absolute path - although the latter has less usefulness, I think! The #include search paths will be used to locate the file and if it is not found an error will be generated. The new check is not optional: if the directive is in a different file to the diagnostic, the file must be specified. Therefore, a number of test-cases have been updated with regard to this. This closes out PR15613. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@179677 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-16[PCH/Modules] Change how macro [re]definitions are de/serialized.Argyrios Kyrtzidis
Previously we would serialize the macro redefinitions as a list, part of the identifier, and try to chain them together across modules individually without having the info that they were already chained at definition time. Change this by serializing the macro redefinition chain and then try to synthesize the chain parts across modules. This allows us to correctly pinpoint when 2 different definitions are ambiguous because they came from unrelated modules.

2012-12-08Finish implementing 'selected constructor' rules for triviality in C++11. InRichard Smith
the cases where we can't determine whether special members would be trivial while building the class, we eagerly declare those special members. The impact of this is bounded, since it does not trigger implicit declarations of special members in classes which merely *use* those classes. In order to determine whether we need to apply this rule, we also need to eagerly declare move operations and destructors in cases where they might be deleted. If a move operation were supposed to be deleted, it would instead be suppressed, and we could need overload resolution to determine if we fall back to a trivial copy operation. If a destructor were implicitly deleted, it would cause the move constructor of any derived classes to be suppressed. As discussed on cxx-abi-dev, C++11's selected constructor rules are also retroactively applied as a defect resolution in C++03 mode, in order to identify that class B has a non-trivial copy constructor (since it calls A's constructor template, not A's copy constructor): struct A { template<typename T> A(T &); }; struct B { mutable A a; }; git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@169673 91177308-0d34-0410-b5e6-96231b3b80d8

2012-11-06[PCH] Write out the ClassTemplateDecl::Common::InjectedClassNameType typeArgyrios Kyrtzidis
reference instead of relying on computing it. In general, if storage is no issue, it is preferable to deserialize info from the PCH instead of trying to recompute it after the PCH was loaded. The incentive to change this now was due to r155303 changing how friend template classes in dependent contexts are handled; such classes can now be chained to a previous template class but the computed InjectedClassNameType may be different due to the extra template parameters from the dependent context. The new handling requires more investigation but, in the meantime, writing out InjectedClassNameType fixes PCH issue in rdar://12627738. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@167425 91177308-0d34-0410-b5e6-96231b3b80d8

2012-10-31[PCH] Remove the stat cache from the PCH file.Argyrios Kyrtzidis
The stat cache became essentially useless ever since we started validating all file entries in the PCH. But the motivating reason for removing it now is that it also affected correctness in this situation: -You have a header without include guards (using "#pragma once" or #import) -When creating the PCH: -The same header is referenced in an #include with different filename cases. -In the PCH, of course, we record only one file entry for the header file -But we cache in the PCH file the stat info for both filename cases -Then the source files are updated and the header file is updated in a way that its size and modification time are the same but its inode changes -When using the PCH: -We validate the headers, we check that header file and we create a file entry with its current inode -There's another #include with a filename with different case than the previously created file entry -In order to get its stat info we go through the cached stat info of the PCH and we receive the old inode -because of the different inodes, we think they are different files so we go ahead and include its contents. Removing the stat cache will potentially break clients that are attempting to use the stat cache as a way of avoiding having the actual input files available. If that use case is important, patches are welcome to bring it back in a way that will actually work correctly (i.e., emit a PCH that is self-contained, coping with literal strings, line/column computations, etc.).

the macros that are #define'd or #undef'd on the command line.
