2012-02-17Index "12" holds the vtable, not "9".Eric Christopher
Fixes lots of gdb testsuite failures. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@150797 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-16Reapply r150631:Eric Christopher
"Add a completed/incomplete type difference. This allows us to have partial types for contexts and forward decls while allowing us to complete types later on for debug purposes. This piggy-backs on the metadata replacement and rauw changes for temporary nodes and takes advantage of the incremental support I added in earlier. This allows us to, if we decide, to limit adding methods and variables to structures in order to limit the amount of debug information output into a .o file. The caching is a bit complicated though so any thoughts on untangling that are welcome." with a fix: - Remove all RAUW during type construction by adding stub versions of types that we later complete. and some TODOs: - Add an RAUW cache for forward declared types so that we can replace them at the end of compilation. - Remove the code that updates on completed types because we no longer need to have that happen. We emit incomplete types on purpose and only want to know when we want to complete them. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@150752 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-09Don't cache the artificial type for the this pointer, there's noEric Christopher
difference in the qual type. This is a workaround for the fact that the type isn't artificial but the this decl is, however, we don't have any way of representing it in the current metadata. For now, however, just don't cache the full type. Fixes rdar://10831526 and probably a couple of others. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@150159 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-07Revert my patches which removed Diagnostic.h includes by moving some ↵Benjamin Kramer
operator overloads out of line. This seems to negatively affect compile time onsome ObjC tests (which use a lot of partial diagnostics I assume). I have to come up with a way to keep them inline without including Diagnostic.h everywhere. Now adding a new diagnostic requires a full rebuild of e.g. the static analyzer which doesn't even use those diagnostics. This reverts commit 6496bd10dc3a6d5e3266348f08b6e35f8184bc99.

2012-01-14constexpr irgen: Add irgen support for APValue::Struct, APValue::Union,Richard Smith
APValue::Array and APValue::MemberPointer. All APValue values can now be emitted as constants. Add new CGCXXABI entry point for emitting an APValue MemberPointer. The other entrypoints dealing with constant member pointers are no longer necessary and will be removed in a later change. Switch codegen from using EvaluateAsRValue/EvaluateAsLValue to VarDecl::evaluateValue. This performs caching and deals with the nasty cases in C++11 where a non-const object's initializer can refer indirectly to previously-initialized fields within the same object. Building the intermediate APValue object incurs a measurable performance hit on pathological testcases with huge initializer lists, so we continue to build IR directly from the Expr nodes for array and record types outside of C++11. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@148178 91177308-0d34-0410-b5e6-96231b3b80d8
