2013-02-20[preprocessor] Split the MacroInfo class into two separate concepts, ↵Argyrios Kyrtzidis
MacroInfo class for the data specific to a macro definition (e.g. what the tokens are), and MacroDirective class which encapsulates the changes to the "macro namespace" (e.g. the location where the macro name became active, the location where it was undefined, etc.) (A MacroDirective always points to a MacroInfo object.) Usually a macro definition (MacroInfo) is where a macro name becomes active (MacroDirective) but splitting the concepts allows us to better model the effect of modules to the macro namespace (also as a bonus it allows better modeling of push_macro/pop_macro #pragmas). Modules can have their own macro history, separate from the local (current translation unit) macro history; MacroDirectives will be used to model the macro history (changes to macro namespace). For example, if "@import A;" imports macro FOO, there will be a new local MacroDirective created to indicate that "FOO" became active at the import location. Module "A" itself will contain another MacroDirective in its macro history (at the point of the definition of FOO) and both MacroDirectives will point to the same MacroInfo object. Introducing the separation of macro concepts is the first part towards better modeling of module macros. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@175585 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-18Replace TypeLoc llvm::cast support to be well-defined.David Blaikie
The TypeLoc hierarchy used the llvm::cast machinery to perform undefined behavior by casting pointers/references to TypeLoc objects to derived types and then using the derived copy constructors (or even returning pointers to derived types that actually point to the original TypeLoc object). Some context is in this thread: http://lists.cs.uiuc.edu/pipermail/llvmdev/2012-December/056804.html Though it's spread over a few months which can be hard to read in the mail archive. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@175462 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-16Rework the traversal of Objective-C categories and extensions toDouglas Gregor
consider (sub)module visibility. The bulk of this change replaces myriad hand-rolled loops over the linked list of Objective-C categories/extensions attached to an interface declaration with loops using one of the four new category iterator kinds: visible_categories_iterator: Iterates over all visible categories and extensions, hiding any that have their "hidden" bit set. This is by far the most commonly used iterator. known_categories_iterator: Iterates over all categories and extensions, ignoring the "hidden" bit. This tends to be used for redeclaration-like traversals. visible_extensions_iterator: Iterates over all visible extensions, hiding any that have their "hidden" bit set. known_extensions_iterator: Iterates over all extensions, whether they are visible to normal name lookup or not. The effect of this change is that any uses of the visible_ iterators will respect module-import visibility. See the new tests for examples. Note that the old accessors for categories and extensions are gone; there are *Raw() forms for some of them, for those (few) areas of the compiler that have to manipulate the linked list of categories directly. This is generally discouraged. Part two of <rdar://problem/10634711>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@172665 91177308-0d34-0410-b5e6-96231b3b80d8

per review discussion in r170365 This does limit these typedefs to being sequences, but no current usage requires them to be contiguous (we could expand this to a more general iterator pair range concept at some point). Also, it'd be nice if SmallVector were constructible directly from an ArrayRef but this is a bit tricky since ArrayRef depends on SmallVectorBaseImpl for the inverse conversion.

Summary: Summary: Keep history of macro definitions and #undefs with corresponding source locations, so that we can later find out all macros active in a specified source location. We don't save the history in PCH (no need currently). Memory overhead is about sizeof(void*)*3*<number of macro definitions and #undefs>+<in-memory size of all #undef'd macros> I've run a test on a file composed of 109 .h files from boost 1.49 on x86-64 linux.

As for CPU overhead, it should only be noticeable when iterating over all macros, and should mostly consist of couple extra dereferences and one comparison per macro + skipping of #undef'd macros. It's less trivial to measure, though, as the preprocessor consumes a very small fraction of compilation time.

2012-04-10[code-complete] Introduce CodeCompletionTUInfo which will be used for cachingArgyrios Kyrtzidis
code-completion related strings specific to a translation unit (ASTContext and related data) CodeCompletionAllocator does such limited caching, by caching the name assigned to a DeclContext*, but that is not the appropriate place since that object has a lifetime that can extend beyond that of an ASTContext. Introduce CodeCompletionTUInfo which will be always tied to a translation unit to do this kind of caching and move the caching of CodeCompletionAllocator into this object, and propagate it to all the places where it will be needed.
