So far the only case observed is "Root":
the JIT stores it as a [5 x i8] = i40 (no kidding);
StoredValue says it should go onto the heap (or its member buffer) as it's an array.
Now the StoredValue knows where to get the array's values from.
git-svn-id: http://root.cern.ch/svn/root/trunk@46494 27541ba8-7e3a-0410-8455-c3a389f83636
The StoredValue has to be heap allocated, so it can be deleted when refcount == 0.
But the value it points to now is simply contained inside the StoredValue if
* it fits into the GenericValue (double,...)
* it is <= 80 bytes.
This grows StoredValue (not Ref!) from 48 to 128 bytes on Linux 64bit.
Given that many OSes allocate an extra 16 bytes for each allocation (i.e. the actual cost is 80-16 bytes), this is still reasonable.

they are no longer needed.
The referenceness of a dummy arg passed by reference
is carried in the value kind, and must be removed from
the type.

findFuntionArgs().
These two functions are now so similar they can be combined
or turned into small wrappers around a common part.

* InterpreterExternalSemaSource::setCallbacks is not needed any more.
It can be set in the constructor instead.

lookups that are expected (by the compiler) to fail and those which should not fail.
I was misled (wasn't thinking at all: Thanks Axel for questioning the checkin)
because I thought we cannot distinguish those two different cases in the test
callback.
Silly mistake:
Revert the changes in the testsuite.
Revert the default setup of the test callback in enableDynamicLookup
The problem is solved by extracting out the function which determines whether
a lookup is not expected to fail. (It still needs better place.)

it looks for typeinfo of the InterpreterCallbacks (compiled with fno-rtti).
*Move the SymbolResolverCallback into InterpreterCallbacks.(h,cpp). Ideally it is
used only in the testsuite so we could hack in the build system to build the
SymbolResolverCallback with fno-rtti and include just the header file but that's
for later.
*Set the symbol resolver callback in enableDynamicLookup for now.
*Clear up the logic behind InterpreterExternalSemaSource and InterpreterCallbacks.
*Now the DynamicIDHandler derives from InterpreterExternalSemaSource.
*Adapt the testsuite to the change.
*Request the InterpreterCallback constructor to be put in the binary.

to be a single object.
ASTReader (aka PCM reader) attaches itself as an ExternalSemaSource.
When cling attaches a callback class and the ASTReader attaches itself they step
on one another's feet.
The patch implements in clang the notion of multiplex ExternalSemaSources and
adapts cling to make use of it. It will be soon proposed to end up in clang
mainline.

no dynamic scopes are involved. The information about a failed lookup comes from
slightly different channel - ExternalSemaSource (if attached to sema).
In order to make the callback LookupObject work when we attach an arbitrary
callback class we should attach ExternalSemaSource to Sema as well. This require
a default implementation for an ExternalSemaSource.

changes anyway.

Use "m_" as member prefix.
Remove adopt() - not needed.
Remove hasValue() - it's meaningless (use isValid() to check validity of value).

Add cling::StoredValueRef: a ref-counted value with automatic storage management.
Update Interpreter to use that instead of cling::Value.
This fixes an issue where the called neded to guess the return type of the wrapper function, such that for instance Interpreter::Evaluate() has storage for the wrapper's aggregate SRet return value if needed.
Instead, the Interpreter now allocates the proper storage for return values, and hands out references to it.
StoredValueRef is tiny (8bytes on 64bit Linux); default allocation is cheap.

TClingCallFunc: provide storage for fArgs.

This is used because we want to have ASTDeclReader and our custom external source

Update cling to follow interface changes; make note of it in cling/LastKnownGoodLLVMSVNRevision.txt.
Remove all (!) patches from ROOT's version of clang; they are all integrated into clang mainline.
ROOT now starts up with modules without errors; doing almost anything hits

* Implement new callback functions - on transaction committed and transaction unloaded.
* Publish the Transaction class so that it can be visible by TCintWithCling.
* Publish the CompilationOptions needed by Transaction.

qualifiers (const std::string) in template arguments.
Fix the handling of default template argument that are not a type.
No longer drop any default argument except for STL collection (as needed by ROOT I/O).
This fixes support of (for example):
#pragma link C++ class std::pair<const std::string,int>+;
#pragma link C++ class ROOT::TArrayProxy<ROOT::TArrayType<double> >+;
(which is ROOT::TArrayProxy<ROOT::TArrayType<double,0> >)

we are given a qualified typedef (the first node is 'Elaborated' rather
than Typedef), for example ROOT::Math::TDataPoint1D.
Also properly handle the case when the scope of the typedef's underlying
type and the scope of the typedef are different. In the case their are
the same, keeping the version given as input (after 'normalizing).
Prevent the desugaring of _any_ typedef declared within the std namespace
(for now hardcoded in AST.cpp) to avoid exposing to ROOT implementation
details (this is a kind of replacement for CINT's customized STL header)

simple lookups.
This checkin slows down the testsuite because there is no LookupHelper::findVarDecl
and we have to #include a lot of headers at runtime.
