Assert that the path from the derived to the base class in CodeGenFunction::GetAddressOfBaseClass is not ambiguous.

function declaration, since it may end up being changed (e.g.,
"extern" can become "static" if a prior declaration was static). Patch
by Enea Zaffanella and Paolo Bolzoni.

llvm-svn: 101826

Have the CXXBaseOrMemberInitializer keep track of whether an initializer initializes a virtual base or not.

llvm-svn: 101004

This introduces FunctionType::ExtInfo to hold the calling convention and the
noreturn attribute. The next patch will extend it to include the regparm
attribute and fix the bug.

Use the new function in EmitClassAggrMemberwiseCopy, fixing the same assert as seen in PR6628 but for arrays this time.

Handle default arguments when calling copy constructors for bases or members when synthesizing a copy constructor. Fixes PR6628.

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

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

llvm-svn: 99787

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.

1) emit base destructors as aliases to their unique base class destructors
under some careful conditions.  This is enabled for the same targets that can
support complete-to-base aliases, i.e. not darwin.

2) Emit non-variadic complete constructors for classes with no virtual bases
as calls to the base constructor.  This is enabled on all targets and in
theory can trigger in situations that the alias optimization can't (mostly
involving virtual bases, mostly not yet supported).

These are bundled together because I didn't think it worthwhile to split them,
not because they really need to be.

llvm-svn: 96842

Fix some bugs with function-try-blocks and simplify normal try-block
code generation.

This implementation excludes a deleting destructor's call to
operator delete() from the function-try-block, which I believe
is correct but which I can't find straightforward support for at
a moment's glance.

llvm-svn: 96670

calling them as subroutines.  This triggers whenever the alias optimization
doesn't, i.e. when the dtor has linkonce linkage or there are virtual bases
or it's the deleting dtor.

llvm-svn: 96605

change.

llvm-svn: 96564

repeatedly reloading from an alloca.  We still need to create the alloca
for debug info purposes (although we currently create it in all cases
because of some abstraction boundaries that're hard to break down).

llvm-svn: 96403

the offset to the virtual bases statically inside of relying on the virtual
base offsets in the object's vtable(s).  This is both more efficient and
sound against the destructor's manipulation of the vtables.

Also extract a few helper routines.

Oh and we seem to pass all tests with an optimized clang now.

If a constructor throws an exception we need to execute the destructors for all fully constructed members. Fixes ctor_dtor_count.cpp in the test suite.

follows (as conservatively as possible) gcc's current behavior:  attributes
written on return types that don't apply there are applied to the function
instead, etc.  Only parse CC attributes as type attributes, not as decl attributes;
don't accepet noreturn as a decl attribute on ValueDecls, either (it still
needs to apply to other decls, like blocks).  Consistently consume CC/noreturn
information throughout codegen;  enforce this by removing their default values
in CodeGenTypes::getFunctionInfo().

llvm-svn: 95436

Revert the new reference binding code; I came up with a way simpler solution for the reference binding bug that is preventing self-hosting.

llvm-svn: 95223

Set the correct vtable pointers _before_ generating code for any member initializers. Fixes about ~2000 clang/LLVM tests in the clang-on-clang build.
