2010-09-03Revert "Another i1 vs. i8 type mismatch issue. This time", it breaks some ↵Daniel Dunbar
projects. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112922 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-03Get rid of the "functions declared 'noreturn' should have a 'void' result ↵Anders Carlsson
type" warning. The rationale behind this is that it is normal for callback functions to have a non-void return type and it should still be possible to mark them noreturn. (JavaScriptCore is a good example of this). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112918 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-03It's not safe to use the generic CXXMethodDecl overload of CGT::getFunctionInfoJohn McCall

2010-09-02Reapply 112850 and 112839 with a constructor for the BinaryOperatorData ↵Tom Care
struct. Clang would zero out the enum and pointer in the struct in some conditions, but GCC would never zero out the values. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112909 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-02Improved error reporting in IdempotentOperationCheckerTom Care
- SourceRange highlighting is only given for the relevant side of the operator (assignments give both) - Added PostVisitBinaryOperator hook to retrieve the ExplodedNode for an operator - Added a BugReporterVisitor to display the last store to every VarDecl in a Stmt - Changed bug reporting to use the new BugReporterVisitor git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112839 91177308-0d34-0410-b5e6-96231b3b80d8

a 'bool' byref variable in memory. Fixes radar 8382559. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112835 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-02Use the unmangled name for the display name in Objective-C debug info. This ↵David Chisnall
should have no effect with the Mac runtime where clang (unlike GCC) uses the display name symbol name. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112833 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-02Fix more i1/i8 pointer madness. Here, an overactive assertionDouglas Gregor
complains when the element type of a C++ "delete" expression is different from what we would expect from the pointer type. When deleting a bool*, we end up with an i1 on one side (where we compute the LLVM type from the Clang bool type) and i8 on the other (where we grab the LLVM type from the LLVM pointer type). I've weakened the assertion appropriately, and the Boost Parallel Graph Library now passes its regression tests. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112821 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-02Fix a crash involving pointer-to-data-members of boolean type. We wereDouglas Gregor
constructing an LLVM PointerType directly from the "bool"'s LLVM type (i1), which resulted in unfortunate pointer type i1*. The fix is to build the LLVM PointerType from the corresponding Clang PointerType, so that we get i8* in the case of a bool. John, please review. I also left a FIXME there because we seem to be dropping "volatile", which would be rather unfortunate. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112819 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-02Abstract IR generation of array cookies into the C++ ABI class andJohn McCall
implement ARM array cookies. Also fix a few unfortunate bugs: - throwing dtors in deletes prevented the allocation from being deleted - adding the cookie to the new[] size was not being considered for overflow (and, more seriously, was screwing up the earlier checks) - deleting an array via a pointer to array of class type was not causing any destructors to be run and was passing the unadjusted pointer to the deallocator - lots of address-space problems, in case anyone wants to support free store in a variant address space :) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112814 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-02For GRExprEngine::EvalBind() (and called visitors), unifiy StoreE and ↵Ted Kremenek
AssignE. Now StoreE (const Stmt*) represents the expression where the store took place, which is the assignment expression if it takes place in an assignment. This removes some conceptual dissidence as well as removes an extra parameter from the Checker::PreVisitBind() visitor. It also improves ranges and source location information in analyzer diagnostics. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112789 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-01Partial fix for PR 8015 (fix is actually by Jordy Rose, and I added a test ↵Ted Kremenek
case for follow-on work). This patch adds a bandaid for RegionStore's limited reasoning about symbolic array values. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112766 91177308-0d34-0410-b5e6-96231b3b80d8

with zext/sext operations, instead of to llvm intrinsics. I have a plan to avoid the clang builtins for these, but it is going to take a little longer and I want to get the NEON intrinsics updated before the 2.8 release. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112764 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-01Implement libclang support for using declarations. Clang actually usesDouglas Gregor
three different kinds of AST nodes to represent using declarations: UsingDecl, UnresolvedUsingValueDecl, and UnresolvedUsingTypenameDecl. These three are collapsed into a single cursor kind for using declarations, since libclang clients don't need the distinction. Several related changes here: - Cursor visitation of the three AST nodes for using declarations - Proper source-range computation for these AST nodes - Using declarations have no USRs, since they don't actually declare any entities. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112730 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-01Split ObjCInterfaceDecl::ReferencedProtocols into two lists: ↵Ted Kremenek
ReferencedProtocols and AllReferencedProtocols. ReferencedProtocols (and thus protocol_begin(), protocol_end()) now only contains the list of protocols that were directly referenced in an @interface declaration. 'all_referenced_protocol_[begin,end]()' now returns the set of protocols that were referenced in both the @interface and class extensions. The latter is needed for semantic analysis/codegen, while the former is needed to maintain the lexical information of the original source. Fixes <rdar://problem/8380046>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112691 91177308-0d34-0410-b5e6-96231b3b80d8

caused by my ABI work.

2010-09-01Improve location information in the representation of namespaceDouglas Gregor
aliases. Previously, the location of the alias was at the "namespace" keyword. Now, it's on the identifier being declared (as is the custom for Clang), and we keep a separate source location for the "namespace" keyword. Also, added a getSourceRange() member function to NamespaceAliasDecl to correctly compute the source range. Finally, removed a bunch of setters from NamespaceAliasDecl and gave ASTReaderDecl friendship so that it could set the corresponding fields directly. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112681 91177308-0d34-0410-b5e6-96231b3b80d8
