2010-10-01Various builtins a require an integer constant. Not providingChris Lattner
one results in an obscure error from the backend that doesn't make sense. Capture this information in the .def files for builtins with a new "I" modifier letter indicating the an argument needs to be an ICE. Nothing uses this yet, but sema will eventually enforce this (eliminating some special cases from semachecking.cpp) and codegen will use this to force an ICE value, preventing backend error messages. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@115302 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-29Move the management of the set of conversion functions in a C++ classDouglas Gregor
into CXXRecordDecl. The only part that we do not handle this way are using declarations, since that would require extra name lookup that we don't currently want to pay for. This fixes <rdar://problem/8459981>, so that LLDB can build a CXXRecordDecl and magically get all of the right bits set. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@115026 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-29Move the maintenance of CXXRecordDecl::DefinitionData's Abstract bitDouglas Gregor
completely into CXXRecordDecl, by adding a new completeDefinition() function. This required a little reshuffling of the final-overrider checking code, since the "abstract" calculation in the presence of abstract base classes needs to occur in CXXRecordDecl::completeDefinition() but we don't want to compute final overriders more than one in the common case. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@115007 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-28Centralize the management of CXXRecordDecl::DefinitionData's Empty bitDouglas Gregor
in CXXRecordDecl itself. Yes, this is also part of <rdar://problem/8459981>. This reinstates r114924, with one crucial bug fix: we were ignoring the implicit fields created by anonymous structs/unions when updating the bits in CXXRecordDecl, which means that a class/struct containing only an anonymous class/struct would be considered "empty". Hilarity follows. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@114980 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-27Clean up the handling of the DeclaredDefaultConstructor andDouglas Gregor
DeclaredCopyConstructor bits in CXXRecordDecl's DefinitionData structure. Rather than having Sema call addedConstructor or set the bits directly at semi-random places, move all of the logic for managing these bits into CXXRecordDecl itself and tie the addedConstructor call into DeclContext::addDecl(). This makes it easier for AST-building clients to get the right bits set in DefinitionData, and is one small part of <rdar://problem/8459981>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@114889 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

2010-09-15one piece of code is responsible for the lifetime of every aggregateJohn McCall
slot. The easiest way to do that was to bundle up the information we care about for aggregate slots into a new structure which demands that its creators at least consider the question. I could probably be convinced that the ObjC 'needs GC' bit should be rolled into this structure. Implement generalized copy elision.
