Remove the -cxx-abi command-line flag. This makes the C++ ABI depend entirely on the target: MS ABI for -win32 triples, Itanium otherwise. It's no longer possible to do weird combinations. To be able to run a test with a specific ABI without constraining it to a specific triple, new substitutions are added to lit: %itanium_abi_triple and %ms_abi_triple can be used to get the current target triple adjusted to the desired ABI. For example, if the test suite is running with the i686-pc-win32 target, %itanium_abi_triple will expand to i686-pc-mingw32.

Special members which are defaulted or deleted on their first declaration are trivial if the implicit declaration would be. Don't forget to set the Trivial flag on the special member as well as on the class. It doesn't seem ideal that we have two separate mechanisms for storing this information, but this patch does not attempt to address that. This leaves us in an interesting position where the has_trivial_X trait for a class says 'yes' for a deleted but trivial X, but is_trivially_Xable says 'no'. This seems to be what the standard requires. llvm-svn: 151465

Correctly propagate defaultedness across template instantiation. This fixes PR9965, but we're not out of the water yet, as we do not successfully handle out-of-line definitions, due to my utter misunderstanding of how we manage templates. llvm-svn: 131920

constexpr irgen: Add irgen support for APValue::Struct, APValue::Union, 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. llvm-svn: 148178
