Due to a mistake on my own part, I need to burn some version numbers.  This does not impact any of the implementation of libc++, and does not impact the ABI in any way.

Previously the analyzer treated all inlined constructors like lvalues,
setting the value of the CXXConstructExpr to the newly-constructed
region. However, some CXXConstructExprs behave like rvalues -- in
particular, the implicit copy constructor into a pass-by-value argument.
In this case, we want only the /contents/ of a temporary object to be
passed, so that we can use the same "copy each argument into the
parameter region" algorithm that we use for scalar arguments.

This may change when we start modeling destructors of temporaries,
but for now this is the last part of <rdar://problem/12137950>.

llvm-svn: 164830

An rvalue has no address, but calling a C++ member function requires a
'this' pointer. This commit makes the analyzer create a temporary region
in which to store the struct rvalue and use as a 'this' pointer whenever
a member function is called on an rvalue, which is essentially what
CodeGen does.

More of <rdar://problem/12137950>. The last part is tracking down the
C++ FIXME in array-struct-region.cpp.

llvm-svn: 164829

Struct rvalues are represented in the analyzer by CompoundVals,
LazyCompoundVals, or plain ConjuredSymbols -- none of which have associated
regions. If the entire structure is going to persist, this is not a
problem -- either the rvalue will be assigned to an existing region, or
a MaterializeTemporaryExpr will be present to create a temporary region.
However, if we just need a field from the struct, we need to create the
temporary region ourselves.

This is inspired by the way CodeGen handles calls to temporaries;
support for that in the analyzer is coming next.

diagnostic count.

If a DiagnosticConsumer sub-class overwrites IncludeInDiagnosticCounts,
this should change diagnostic counts. However, it currently also
influences Diag.ErrorOccurred, which in turn influences the behavior of
parsing and semantic analysis (in a way that can make it crash).

2. As part of this, added assembly format FEXT_RI16_SP_explicit_ins and
moved other lines for FEXT_RI16 formats to be in the right place in the code.
3. Added mayLoad and mayStore assignements for the load/store instructions added and for ones already there that did not have this assignment.
4. Another patch will deal with the problem of load/store byte/halfword to the stack. This is a particular Mips16 problem.

Two changes:  1)  I still didn't have the ABI correct to match the gcc-4.2 std::string under the exception classes.  I think the changes to stdexcept.cpp have got that down now.  2) On Apple platforms I'm seeing visibility bugs in applications with respect to type_info's being hidden.  This is causing dynamic_cast to malfunction because there are multiple type_info's running around for one type within an application, making dynamic_cast believe that one type is actually multiple types.  As a stop gap measure I'm trying to detect this error, print out an error message, but continue with the most likely desired result.  This is all under __APPLE__.  This behavior can be expanded to other platforms if desired.

We can now do:

Specify a path to a debug symbols file:
(lldb) add-dsym <path-to-dsym>

Go and download the dSYM file for the "libunc.dylib" module in your target:
(lldb) add-dsym --shlib libunc.dylib

Go and download the dSYM given a UUID:
(lldb) add-dsym --uuid <UUID>

Go and download the dSYM file for the current frame:
(lldb) add-dsym --frame
