2009-05-30Printing for using directives, e.g.,Douglas Gregor
using namespace std::debug; Extended UsingDirectiveDecl to store the nested-name-specifier that precedes the nominated namespace. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72614 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-30Add a Stmt::printPretty overload which takes an ASTContext; start Eli Friedman
transitioning callers over to pass one in. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72609 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-30Expose an API to print a group of decls (like "int a,b;"). Eli Friedman
Make StmtPrinter use DeclPrinter to print all declarations. Merge declarations in the limited case of an unnamed TagDecl followed by one or more declarations using that TagDecl directly. Change SuppressTypeSpecifiers to the more general SuppressSpecifiers, and use it to suppress stuff like "typedef" and "extern". Replace OwnedTag with SuppressTag, since it's more convenient to print declarations from DeclPrinter at the moment. improvements to declaration printing. Fix pretty-printing for K&R function definitions and __builtin_va_arg. We're now to the point where the pretty-printing output for non-trivial programs can actually be piped back into clang. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72608 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-30Add support for PrintingPolicy::SuppressTypeSpecifiers to type printing. Eli Friedman
(I have a work-in-progress patch which uses this.) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72598 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-30Refactor and clean up the AST printer, so that it uses a DeclVisitor,Douglas Gregor
walks through DeclContexts properly, and prints more of the information available in the AST. The functionality is still available via -ast-print, -ast-dump, etc., and also via the new member functions Decl::dump() and Decl::print(). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72597 91177308-0d34-0410-b5e6-96231b3b80d8

2009-05-29Create a new PrintingPolicy class, which we pass down through the ASTDouglas Gregor
printing logic to help customize the output. For now, we use this rather than a special flag to suppress the "struct" when printing "struct X" and to print the Boolean type as "bool" in C++ but "_Bool" in C. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72590 91177308-0d34-0410-b5e6-96231b3b80d8

2009-05-29If a declarator group declares a type, make sure to add that declaration Eli Friedman
to the DeclGroup. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72559 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-28When we parse a tag specifier, keep track of whether that tagDouglas Gregor
specifier resulted in the creation of a new TagDecl node, which happens either when the tag specifier was a definition or when the tag specifier was the first declaration of that tag type. This information has several uses, the first of which is implemented in this commit: 1) In C++, one is not allowed to define tag types within a type specifier (e.g., static_cast<struct S { int x; } *>(0) is ill-formed) or within the result or parameter types of a function. We now diagnose this. 2) We can extend DeclGroups to contain information about any tags that are declared/defined within the declaration specifiers of a variable, e.g., struct Point { int x, y, z; } p; This will help improve AST printing and template instantiation, among other things. 3) For C99, we can keep track of whether a tag type is defined within the type of a parameter, to properly cope with cases like, e.g., int bar(struct T2 { int x; } y) { struct T2 z; } We can also do similar things wherever there is a type specifier, e.g., to keep track of where the definition of S occurs in this legal C99 code: (struct S { int x, y; } *)0 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72555 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-28Introduced DeclContext::isDependentContext, which determines whether aDouglas Gregor
given DeclContext is dependent on type parameters. Use this to properly determine whether a TagDecl is dependent; previously, we were missing the case where the TagDecl is a local class of a member function of a class template (phew!). Also, make sure that, when we instantiate declarations within a member function of a class template (or a function template, eventually), that we add those declarations to the "instantiated locals" map so that they can be found when instantiating declaration references. Unfortunately, I was not able to write a useful test for this change, although the assert() that fires when uncommenting the FIXME'd line in test/SemaTemplate/instantiate-declref.cpp tells the "experienced user" that we're now doing the right thing. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72526 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-27Reimplement much of the way that we track nested classes in theDouglas Gregor
parser. Rather than placing all of the delayed member function declarations and inline definitions into a single bucket corresponding to the top-level class, we instead mirror the nesting structure of the nested classes and place the delayed member functions into their appropriate place. Then, when we actually parse the delayed member function declarations, set up the scope stack the same way as it was when we originally saw the declaration, so that we can find, e.g., template parameters that are in scope. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72502 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-27restrict is not a keyword in gnu89 mode. Change TokenKinds.def to Eli Friedman
reflect that. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72500 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-27Reintroduce the home for exception specs, and make Sema fill it. However, ↵Sebastian Redl
keep the spec out of the canonical type this time. Net effect is currently nothing, because the spec isn't checked anywhere. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72498 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-27Add a big test case for I-C-Es in C++, and a fix to make it work. The fix ↵Sebastian Redl
might not be the right way to do it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72490 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-27Enumeration declarations that were instantiated from an enumerationDouglas Gregor
within a template now have a link back to the enumeration from which they were instantiated. This means that we can now find the instantiation of an anonymous enumeration. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72482 91177308-0d34-0410-b5e6-96231b3b80d8

2009-05-27Convert ObjC qualified type clients over to using iterators.Steve Naroff

2009-05-26When evaluating a VarDecl as a constant or determining whether it isDouglas Gregor
an integral constant expression, maintain a cache of the value and the is-an-ICE flag within the VarDecl itself. This eliminates exponential-time behavior of the Fibonacci template metaprogram. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72428 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-26Fix for PR4140: Add the start of a Linux toolchain (basically, just Eli Friedman
barely enough to get the given usage of -print-file-name working). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72412 91177308-0d34-0410-b5e6-96231b3b80d8

2009-05-22Modify begin()/end() for AsmStmt iterators to handle the case when Exprs.empty()Ted Kremenek
is true. Because of recent changes to llvm::SmallVector, using these iterators when Exprs was empty would cause an assertion failure. This fixes: PR 4245. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72286 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-22Cannot type cast @selector expressions.Fariborz Jahanian

2009-05-22Representation of and template instantiation for memberDouglas Gregor
expressions. This change introduces another AST node, CXXUnresolvedMemberExpr, that captures member references (x->m, x.m) when the base of the expression (the "x") is type-dependent, and we therefore cannot resolve the member reference yet. Note that our parsing of member references for C++ is still quite poor, e.g., we don't handle x->Base::m or x->operator int. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72281 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-22This patch adds support for sender-aware dispatch in Objective-C for the GNU ↵Fariborz Jahanian
runtime, when compiled with -fobjc-sender-dependent-dispatch. This is used in AOP, COP, implementing object planes, and a few other things. Patch by David Chisnall. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72275 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-22Don't warn about -funit-at-a-time, and reject -fno-unit-at-a-time.Daniel Dunbar
- We could just warn about -fno-unit-at-a-time, but in practice people using it probably aren't going to get what they want out of clang. Also, use "clang" specified error for unsupported things instead of driver unsupported error. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72272 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-22(Next runtime only) check to see if class implements forwardInvocation method Fariborz Jahanian

2009-05-22Remove ParseSimpleParenExpression.Argyrios Kyrtzidis
Embed its functionality into it's only user, ParseCXXCasts. CXXCasts now get the "actual" expression directly, they no longer always receive a ParenExpr. This is better since the parentheses are always part of the C++ casts syntax. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72257 91177308-0d34-0410-b5e6-96231b3b80d8
