2009-02-27Fix enumeration in switch warnings, plus misc comment changes. No Eli Friedman
behavior change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65658 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-27Fix PR3612. We ensure that we add builtins to the GlobalDeclMap andMike Stump
we ensure that things added to the module can be found even when they are not in GlobalDeclMap. The later is for increased flexibility, should someone want to do something tricky like extern "Ada" in the same module. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65657 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-27In BuildAnonymousStructUnionMemberReference, we shouldn't invalidate OpLoc whenTed Kremenek
building nested member expressions. This location is used to determine the range of the entire expression, and the expression itself already has its location inherited from its Base. This fixes <rdar://problem/6629829>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65650 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-27Implement the basic approach for instantiating types, with a lot of FIXME'dDouglas Gregor
stubs for those types we don't yet know how to instantiate (everything that isn't a template parameter!). We now instantiate default arguments for template type parameters when needed. This will be our testbed while I fill out the remaining type-instantiation logic. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65649 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-27upgrade various 'implicit int' warnings from an ext-warn to warning when notChris Lattner
in C89 mode. This makes it enabled by default instead of only enabled with -pedantic. Clang defaults to c99 mode, so people will see this more often than with GCC, but they can always use -std=c89 if they really want c89. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65647 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-26Create a new TypeNodes.def file that enumerates all of the types,Douglas Gregor
giving them rough classifications (normal types, never-canonical types, always-dependent types, abstract type representations) and making it far easier to make sure that we've hit all of the cases when decoding types. Switched some switch() statements on the type class over to using this mechanism, and filtering out those things we don't care about. For example, CodeGen should never see always-dependent or non-canonical types, while debug info generation should never see always-dependent types. More switch() statements on the type class need to be moved over to using this approach, so that we'll get warnings when we add a new type then fail to account for it somewhere in the compiler. As part of this, some types have been renamed: TypeOfExpr -> TypeOfExprType FunctionTypeProto -> FunctionProtoType FunctionTypeNoProto -> FunctionNoProtoType There shouldn't be any functionality change... git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65591 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-26Introduce code modification hints into the diagnostics system. When weDouglas Gregor
know how to recover from an error, we can attach a hint to the diagnostic that states how to modify the code, which can be one of: - Insert some new code (a text string) at a particular source location - Remove the code within a given range - Replace the code within a given range with some new code (a text string) Right now, we use these hints to annotate diagnostic information. For example, if one uses the '>>' in a template argument in C++98, as in this code: template<int I> class B { }; B<1000 >> 2> *b1; we'll warn that the behavior will change in C++0x. The fix is to insert parenthese, so we use code insertion annotations to illustrate where the parentheses go: test.cpp:10:10: warning: use of right-shift operator ('>>') in template argument will require parentheses in C++0x B<1000 >> 2> *b1; ^ ( ) Use of these annotations is partially implemented for HTML diagnostics, but it's not (yet) producing valid HTML, which may be related to PR2386, so it has been #if 0'd out. In this future, we could consider hooking this mechanism up to the rewriter to actually try to fix these problems during compilation (or, after a compilation whose only errors have fixes). For now, however, I suggest that we use these code modification hints whenever we can, so that we get better diagnostics now and will have better coverage when we find better ways to use this information. This also fixes PR3410 by placing the complaint about missing tokens just after the previous token (rather than at the location of the next token). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65570 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-26Remove short-circuit evaluation and the extension warnings. I'm Eli Friedman
pretty sure we want to keep constant expression verification outside of Evaluate. Because of that, the short-circuit evaluation doesn't generally make sense, and the comma warning doesn't make sense in its current form. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65525 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-26Rewrite of isIntegerConstantExpr to be centered around Evaluate. This Eli Friedman
is a rather big change, but I think this is the direction we want to go; the code is significantly shorter now, and it doesn't duplicate Evaluate code. There shouldn't be any visible changes as far as I know. There has been some movement towards putting ICE handling into Evaluate (for example, VerifyIntegerConstantExpression uses Evaluate instead of isICE). This patch is sort of the opposite of the approach, making ICE handling work without Evaluate being aware of it. I think this approach is better because it separates the code that does the constant evaluation from code that's calculating a rather arbitrary predicate. The one thing I don't really like about this patch is that the handling of commas in C99 complicates it signficantly. (Seriously, what was the standards committee thinking when they wrote that part?) I think I've come up with a decent approach, but it doesn't feel ideal. I might add some way to check for evaluated commas from Evaluate in a subsequent patch; that said, it might not be worth bothering. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65524 91177308-0d34-0410-b5e6-96231b3b80d8
