git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@120131 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-18Refactoring of Diagnostic class.Argyrios Kyrtzidis
-Move the stuff of Diagnostic related to creating/querying diagnostic IDs into a new DiagnosticIDs class. -DiagnosticIDs can be shared among multiple Diagnostics for multiple translation units. -The rest of the state in Diagnostic object is considered related and tied to one translation unit. -Have Diagnostic point to the SourceManager that is related with. Diagnostic can now accept just a SourceLocation instead of a FullSourceLoc. -Reflect the changes to various interfaces. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@119730 91177308-0d34-0410-b5e6-96231b3b80d8

2010-10-31Baby steps towards using only CharUnits for base class offsets in ↵Anders Carlsson
ASTRecordLayout. Start by storing the offsets in CharUnits in the ASTRecordLayout object. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@117869 91177308-0d34-0410-b5e6-96231b3b80d8

2010-10-14Store in PCH the key function of C++ class to avoid deserializing the ↵Argyrios Kyrtzidis
complete declaration context in order to compute it. Progress for rdar://7260160. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116508 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-13Embrace C++ ABI 5.2.6 and consider that template instantiations don't have ↵Argyrios Kyrtzidis
key functions (same as GCC). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116391 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-22Implement -Wpadded and -Wpacked.Argyrios Kyrtzidis
-Wpadded warns when undesired padding is introduced in a struct. (rdar://7469556) -Wpacked warns if a struct is given the packed attribute, but the packed attribute has no effect on the layout or the size of the struct. Such structs may be mis-aligned for little benefit. The warnings are emitted at the point where layout is calculated, that is at RecordLayoutBuilder. To avoid calculating the layouts of all structs regardless of whether they are needed or not, I let the layouts be lazily constructed when needed. This has the disadvantage that the above warnings will be emitted only when they are used for IR gen, and not e.g with -fsyntax-only: $ cat t.c struct S { char c; int i; }; void f(struct S* s) {} $ clang -fsyntax-only -Wpadded t.c $ clang -c -Wpadded t.c -o t.o t.c:3:7: warning: padding struct 'struct S' with 3 bytes to align 'i' [-Wpadded] int i; ^ 1 warning generated. This is a good tradeoff between providing the warnings and not calculating layouts for all structs in case the user has enabled a couple of rarely used warnings. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@114544 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-25Use a smart pointer instead of delete.Argyrios Kyrtzidis
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112005 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-23Add a virtual destructor to the base of another class hierarchy with virtualChandler Carruth
methods. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111804 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-19Add some enum goodness as requested by Chris. Now instead of storing theCharles Davis
active C++ ABI as a raw string, we store it as an enum. This should improve performance somewhat. And yes, this time, I started from a clean build directory, and all the tests passed. :) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111507 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111498 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-19Add a special RecordLayoutBuilder for the Microsoft C++ ABI.Charles Davis
All it does right now is add space for two vtable pointers instead of one when a class has both virtual methods and virtual bases. This is a requirement of the Microsoft ABI, since it has separate vtables for methods and bases. Other stuff will come up over time, but we'll cross those bridges when we get to them. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111493 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-18Generate Attr subclasses with TableGen.Sean Hunt
Now all classes derived from Attr are generated from TableGen. Additionally, Attr* is no longer its own linked list; SmallVectors or Attr* are used. The accompanying LLVM commit contains the updates to TableGen necessary for this. Some other notes about newly-generated attribute classes: - The constructor arguments are a SourceLocation and a Context&, followed by the attributes arguments in the order that they were defined in Attr.td - Every argument in Attr.td has an appropriate accessor named getFoo, and there are sometimes a few extra ones (such as to get the length of a variadic argument). Additionally, specific_attr_iterator has been introduced, which will iterate over an AttrVec, but only over attributes of a certain type. It can be accessed through either Decl::specific_attr_begin/end or the global functions of the same name. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111455 91177308-0d34-0410-b5e6-96231b3b80d8

2010-06-29Sema: Fix a subtle i64 -> i32 truncation which broke layout of large structuresDaniel Dunbar
with bit-fields. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@107185 91177308-0d34-0410-b5e6-96231b3b80d8
2010-06-29Delete assert in ComputeKeyFunction. The function runs fine without it, sinceJeffrey Yasskin
there's an explicit guard on isPolymorphic, and virtual bases don't affect the key function calculation. This allows people to call ASTContext::getKeyFunction on arbitrary classes. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@107143 91177308-0d34-0410-b5e6-96231b3b80d8

2010-06-13Implement part of the EmptySubobjectMap optimization described in PR6998. We ↵Anders Carlsson
still need to do this for bases. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@105919 91177308-0d34-0410-b5e6-96231b3b80d8

2010-05-30Turn on the new empty base subobject tracking code. It's a bit faster than ↵Anders Carlsson
the previous code. However, it still has quadratic performance, something which I intend to fix shortly in a subsequent patch. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@105161 91177308-0d34-0410-b5e6-96231b3b80d8

2010-05-29Change RecordLayoutBuilder::LayoutBase to take a BaseSubobjectInfo. No ↵Anders Carlsson
functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@105112 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-29Rework the way virtual primary bases are added when laying out classes. ↵Anders Carlsson
Instead of doing it as a separate step, we now use the BaseSubobjectInfo and use it when laying out the bases. This fixes a bug where we would either not add a primary virtual base at all, or add it at the wrong offset. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@105110 91177308-0d34-0410-b5e6-96231b3b80d8

2010-05-29Change RecordLayoutBuilder::LayoutNonVirtualBase to take a ↵Anders Carlsson
