2011-12-06Switch a cast to a dyn_cast and check the pointer before using. Fixes a crashRichard Trieu
in the following code: void test4(bool (&x)(void)) { while (x); } git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@145918 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-05Add a warning for implicit conversion from function literals (and staticLang Hames

2011-11-28When checking a call to a builtin atomic operation, be sure toDouglas Gregor
consider the _<width> variants as well, which we'll see if we're performing the type checking in a template instantiation where the call expression itself was originally not type-dependent. Fixes PR11411. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@145248 91177308-0d34-0410-b5e6-96231b3b80d8
2011-11-16Fix Neon builtin pointer argument checking for "sret" builtins.Bob Wilson
The code for checking Neon builtin pointer argument types was assuming that there would only be one pointer argument. But, for vld2-4 builtins, the first argument is a special sret pointer where the result will be stored. So, instead of scanning all the arguments to find a pointer, have TableGen figure out the index of the pointer argument that needs checking. That's better than scanning all the arguments regardless. <rdar://problem/10448804> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@144834 91177308-0d34-0410-b5e6-96231b3b80d8
2011-11-10Constant expression evaluation: support for evaluation of structs and unions ofRichard Smith
literal types, as well as derived-to-base casts for lvalues and derived-to-virtual-base casts. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@144265 91177308-0d34-0410-b5e6-96231b3b80d8
2011-11-10There's no good reason to track temporaries in ExprWithCleanups,John McCall
but it is sometimes useful to track blocks. Do so. Also optimize the storage of these expressions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@144263 91177308-0d34-0410-b5e6-96231b3b80d8
2011-11-08Mark the overloaded atomic builtins as having custom type checking,Douglas Gregor
which they do. This avoids all of the default argument promotions that we (1) don't want, and (2) undo during that custom type checking, and makes sure that we don't run into trouble during template instantiation. Fixes PR11320. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@144110 91177308-0d34-0410-b5e6-96231b3b80d8
2011-11-08Check pointer types for arguments of Neon load/store macros. rdar://9958031Bob Wilson
The Neon load/store intrinsics need to be implemented as macros to avoid hiding alignment attributes on the pointer arguments, and the macros can only evaluate those pointer arguments once (in case they have side effects), so it has been hard to get the right type checking for those pointers. I tried various alternatives in the arm_neon.h header, but it's much more straightforward to just check directly in Sema. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@144075 91177308-0d34-0410-b5e6-96231b3b80d8
2011-11-08Clean up type flags for overloaded Neon builtins. No functional change.Bob Wilson
This patch just adds a simple NeonTypeFlags class to replace the various hardcoded constants that had been used until now. Unfortunately I couldn't figure out a good way to avoid duplicating that class between clang and TableGen, but since it's small and rarely changes, that's not so bad. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@144054 91177308-0d34-0410-b5e6-96231b3b80d8

2011-11-06Change the AST representation of operations on Objective-CJohn McCall
property references to use a new PseudoObjectExpr expression which pairs a syntactic form of the expression with a set of semantic expressions implementing it. This should significantly reduce the complexity required elsewhere in the compiler to deal with these kinds of expressions (e.g. IR generation's special l-value kind, the static analyzer's Message abstraction), at the lower cost of specifically dealing with the odd AST structure of these expressions. It should also greatly simplify efforts to implement similar language features in the future, most notably Managed C++'s properties and indexed properties. Most of the effort here is in dealing with the various clients of the AST. I've gone ahead and simplified the ObjC rewriter's use of properties; other clients, like IR-gen and the static analyzer, have all the old complexity *and* all the new complexity, at least temporarily. Many thanks to Ted for writing and advising on the necessary changes to the static analyzer. I've xfailed a small diagnostics regression in the static analyzer at Ted's request. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@143867 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-29Rename Expr::Evaluate to Expr::EvaluateAsRValue to make it clear that it willRichard Smith
implicitly perform an lvalue-to-rvalue conversion if used on an lvalue expression. Also improve the documentation of Expr::Evaluate* to indicate which of them will accept expressions with side-effects. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@143263 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-28Fix for PR9751 to change the behavior of -Wformat warnings. If the formatRichard Trieu
string is part of the function call, then there is no difference. If the format string is not, the warning will point to the call site and a note will point to where the format string is. Fix-it hints for strings are moved to the note if a note is emitted. This will prevent changes to format strings that may be used in multiple places. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@143168 91177308-0d34-0410-b5e6-96231b3b80d8

2011-10-25Introduce a placeholder type for "pseudo object"John McCall
expressions: expressions which refer to a logical rather than a physical l-value, where the logical object is actually accessed via custom getter/setter code. A subsequent patch will generalize the AST for these so that arbitrary "implementing" sub-expressions can be provided. Right now the only client is ObjC properties, but this should be generalizable to similar language features, e.g. Managed C++'s __property methods. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@142914 91177308-0d34-0410-b5e6-96231b3b80d8
