Flip the switch and use the new vtable layout code for everything. I've verified that this passes a self-host but I'll let the bots self host as well before removing the now dead code.

This reduces '-c -g' time on one file in 403.gcc by 12%.

storage for that partial diagnostic via the ASTContext's
BumpPtrAllocator rather than using up slots in the ASTContext's
cache. Now that we do this, we don't have to worry about destroying
dependent diagnostics when destroying a DependentStoredDeclsMap.

cache of PartialDiagnostic::Storage objects into an allocator within
the ASTContext. This eliminates a significant amount of malloc
traffic, for a 10% performance improvement in -fsyntax-only wall-clock
time with 403.gcc's combine.c.

Also, eliminate the RequireNonAbstractType hack I put in earlier,
which was but a symptom of this larger problem.

Fixes <rdar://problem/7806091>.

a 2.47% speedup in 403.gcc.

When collecting virtual bases it's very important to use the canonical type of the base class. Otherwise, we might add the same virtual base class twice if the virtual base is an instantiated template. Fixes PR6251.

end of a struct/class/union in C++, from Justin Bogner!

Fix a nasty bug in the virtual base computation which would lead to us initializing virtual bases in the wrong order.

llvm-svn: 99806

This patch moves some methods from QualType to Type and changes the users to
use -> instead of .

llvm-svn: 99805

More vtable work - it's not possible to use the new vtable code for everything by setting a flag inside CGVtable.cpp. My plan is to run some tests and bootstrap and once that's done flip the bit.

Sprinkle some sed dust over check-ztt to make it work with newer clang asm output. (I am not a sed expert so this might be terribly inefficient :)

llvm-svn: 99802

Only add thunks for the most derived class. This fixes some link errors I was seeing in files generated by the vtable tester utility.

llvm-svn: 99801

Flip the switch to always get vtables from the VTT when necessary, I've verified that clang bootstraps with this.

Make sure to sort the vtable thunks by their vtable index :) With this we now pass the test from http://www.codesourcery.com/public/cxx-abi/abi-examples.html#vtable-ctor successfully.

Use construction vtables when needed. This is currently guarded by -fdump-vtable-layouts since it doesn't work 100% yet :)

llvm-svn: 99787

Two bug fixes, we weren't updating the thunk index when creating the vtable initializer and we weren't storing the secondary virtual pointer indices.

llvm-svn: 99786

Make default arguments to getFunctionNoProtoType an all or nothing option (as they already are in practise).

llvm-svn: 99785

llvm-svn: 99783

Reapply r99775 with a fix for a silly bug - we were setting the vtable pointer for all bases, even those without a vtable pointer :)

llvm-svn: 99777

llvm-svn: 99776

More improvements to setting the vtable pointer. We now no longer set the vtable pointer for non-virtual primary bases. We also do a pre-order traversal of the class hierarchy; this is necessary in order to get the right vbase offset offsets in base ctors/dtors.

llvm-svn: 99775

check deduced non-type template arguments and template template
arguments against the template parameters for which they were deduced,
performing conversions as appropriate so that deduced template
arguments get the same treatment as explicitly-specified template
arguments. This is the bulk of PR6723.

Also keep track of whether deduction of a non-type template argument
came from an array bound (vs. anywhere else). With this information,
we enforce C++ [temp.deduct.type]p17, which requires exact type
matches when deduction deduces a non-type template argument from
something that is not an array bound.

Finally, when in a SFINAE context, translate the "zero sized
arrays are an extension" extension diagnostic into a hard error (for
better standard conformance), which was a minor part of PR6723.
