2013-02-09Release notes: mention support for Unicode and UCNs in identifiers.Jordan Rose
I'm using the name "Extended Identifiers" for the feature because that's what GCC calls them. According to the standard, the new feature is "universal character names are now allowed in identifiers", but the more interesting "feature" is that identifiers can now contain Unicode characters, however they are written. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174798 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-09Ensure that type definitions present in just-loaded modules areDouglas Gregor
visible. The basic problem here is that a given translation unit can use forward declarations to form pointers to a given type, say, class X; X *x; and then import a module that includes a definition of X: import XDef; We will then fail when attempting to access a member of X, e.g., x->method() because the AST reader did not know to look for a default of a class named X within the new module. This implementation is a bit of a C-centric hack, because the only definitions that can have this property are enums, structs, unions, Objective-C classes, and Objective-C protocols, and all of those are either visible at the top-level or can't be defined later. Hence, we can use the out-of-date-ness of the name and the identifier-update mechanism to force the update. In C++, we will not be so lucky, and will need a more advanced solution, because the definitions could be in namespaces defined in two different modules, e.g., // module 1 namespace N { struct X; } // module 2 namespace N { struct X { /* ... */ }; } One possible implementation here is for C++ to extend the information associated with each identifier table to include the declaration IDs of any definitions associated with that name, regardless of context. We would have to eagerly load those definitions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174794 91177308-0d34-0410-b5e6-96231b3b80d8

Add warnings under -Wc++11-compat, -Wc++98-compat, and -Wc99-compat when a particular UCN is incompatible with a different standard, and -Wunicode when a UCN refers to a surrogate character in C++03. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174788 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-09[analyzer] Invalidation checker: move the "missing implementation" checkAnna Zaks
The missing definition check should be in the same category as the missing ivar validation - in this case, the intent is to invalidate in the given class, as described in the declaration, but the implementation does not perform the invalidation. Whereas the MissingInvalidationMethod checker checks the cases where the method intention is not to invalidate. The second checker has potential to have a much higher false positive rate. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174787 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-08[analyzer] IvarInvalidation: add annotation for partial invalidationAnna Zaks
The new annotation allows having methods that only partially invalidate IVars and might not be called from the invalidation methods directly (instead, are guaranteed to be called before the invalidation occurs). The checker is going to trust the programmer to call the partial invalidation method before the invalidator.This is common in cases when partial object tear down happens before the death of the object. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174779 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-08Pull Lexer's CharInfo table out for general use throughout Clang.Jordan Rose
Rewriting the same predicates over and over again is bad for code size and code maintainence.

The next commit will try to clean up uses of <ctype.h> functions within Clang. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174765 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-08Implement a tiny expression parser to improve formatting decisions.Daniel Jasper
With this patch, the formatter introduces 'fake' parenthesis according to the operator precedence of binary operators.

2013-02-08Improve filechecking of volatile test.Tim Northover
My previous attempt was extremely deficient, allowing more volatiles to be introduced and not even checking all of the ones that are present. This attempt doesn't try to keep track of the values stored or offsets within particular objects, just that the correct objects are accessed in a correctly volatile manner throughout. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174700 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-08CMake: Include Clang unit tests in check-clang target in standalone builds.Jordan Rose
Also, remove CLANG_BUILD_TESTS option. It won't have consistent behavior between standalone and non-standalone builds, so I'm not going to bother hooking it up for standalone builds. LLVM_BUILD_TESTS will continue to control unit test inclusion in the "all" target in non-standalone builds. Finally, fix the default value of CLANG_INCLUDE_TESTS, which was being set to the boolean value of "LLVM_INCLUDE_TESTS", i.e. OFF, rather than actually reading the variable ${LLVM_INCLUDE_TESTS}! If you picked up my earlier commit, YOU WILL HAVE TO MANUALLY SET THIS OPTION BACK ON. My apologies!

2013-02-08CMake: Optionally allow running the Clang unit tests in standalone builds.Jordan Rose
The reason this is not enabled by default is because there is no way for Clang to guarantee that the LLVM unit testing infrastruture has been built. However, if it /has/ been built, there's no reason why the standalone Clang build can't use it! This should have no effect on existing builds -- in a combined build the value of the CLANG_INCLUDE_TESTS option defaults to the LLVM equivalent, and in a standalone build it defaults to off. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174691 91177308-0d34-0410-b5e6-96231b3b80d8

overloads of a name by claiming that there are no lookup results for that name in modules while loading the names from the module. Lookups in deserialization really don't want to find names which they themselves are in the process of introducing. This also has the pleasant side-effect of automatically caching PCH lookups which found no names.
