Zachary Turner 9739a552c2 Fix DataExtractor failures.
Some code that doesn't get compiled on Windows had some references
that needed updating, and I missed those.

Zachary Turner 29cb868aa4 Isolate Target-specific functionality of DataExtractor.
In an effort to move the various DataBuffer / DataExtractor
classes from Core -> Utility, we have to separate the low-level
functionality from the higher level functionality.  Only a
few functions required anything other than reading/writing
raw bytes, so those functions are separated out into a
more appropriate area.  Specifically, Dump() and DumpHexBytes()
are moved into free functions in Core/DumpDataExtractor.cpp,
and GetGNUEHPointer is moved into a static function in the
only file that it's referenced from.

Zachary Turner 6f9e690199 Move Log from Core -> Utility.
All references to Host and Core have been removed, so this
class can now safely be lowered into Utility.

Zachary Turner c156427ded Don't allow direct access to StreamString's internal buffer.
This is a large API change that removes the two functions from
StreamString that return a std::string& and a const std::string&,
and instead provide one function which returns a StringRef.

Direct access to the underlying buffer violates the concept of
a "stream" which is intended to provide forward only access,
and makes porting to llvm::raw_ostream more difficult in the
future.

Kate Stone b9c1b51e45 *** This commit represents a complete reformatting of the LLDB source code
*** to conform to clang-format’s LLVM style.  This kind of mass change has
*** two obvious implications:

Firstly, merging this particular commit into a downstream fork may be a huge
effort.  Alternatively, it may be worth merging all changes up to this commit,
performing the same reformatting operation locally, and then discarding the
merge for this particular commit.  The commands used to accomplish this
reformatting were as follows (with current working directory as the root of
the repository):

    find . \( -iname "*.c" -or -iname "*.cpp" -or -iname "*.h" -or -iname "*.mm" \) -exec clang-format -i {} +
    find . -iname "*.py" -exec autopep8 --in-place --aggressive --aggressive {} + ;

The version of clang-format used was 3.9.0, and autopep8 was 1.2.4.

Secondly, “blame” style tools will generally point to this commit instead of
a meaningful prior commit.  There are alternatives available that will attempt
to look through this change and find the appropriate prior commit.  YMMV.

Adrian Prantl 6aeba89e89 Support floating point values in 128-bit SSE vector registers
The System-V x86_64 ABI requires floating point values to be passed
in 128-but SSE vector registers (xmm0, ...). When printing such a
variable this currently yields an <invalid load address>.

This patch makes LLDB's DWARF expression evaluator accept 128-bit
registers as scalars. It also relaxes the check that the size of the
result of the DWARF expression be equal to the size of the variable to a
greater-than. DWARF defers to the ABI how smaller values are being placed
in a larger register.

Implementation note: I found the code in Value::SetContext() that changes
the m_value_type after the fact to be questionable. I added a sanity check
that the Value's memory buffer has indeed been written to (this is
necessary, because we may have a scalar value in a vector register), but
really I feel like this is the wrong place to be setting it.

Sean Callanan 9fda9d2177 Add PersistentVariableDelegate to handle language-specific dematerialization.
The concept here is that languages may have different ways of communicating
results.  In particular, languages may have different names for their result
variables and in fact may have multiple types of result variables (e.g.,
error results).  Materializer was tied to one specific model of result handling.

Instead, now UserExpressions can register their own handlers for the result
variables they inject.  This allows language-specific code in Materializer to
be moved into the expression parser plug-in, and it simplifies Materializer.
These delegates are subclasses of PersistentVariableDelegate.

PersistentVariableDelegate can provide the name of the result variable, and is
notified when the result variable is populated.  It can also be used to touch
persistent variables if need be, updating language-specific state.  The
UserExpression owns the delegate and can decide on its result based on
consulting all of its (potentially multiple) delegates.

The user expression itself now makes the determination of what the final result
of the expression is, rather than relying on the Materializer, and I've added a
virtual function to UserExpression to allow this.

Sean Callanan 9301ec1191 Eliminated redundant "constructors" for ClangExpressionVariable.
The ClangExpressionVariable::CreateVariableInList functions looked cute, but                                                                                                                                           
caused more confusion than they solved.  I removed them, and instead made sure                                                                                                                                         
that there are adequate facilities for easily adding newly-constructed                                                                                                                                                 
ExpressionVariables to lists.      

I also made some of the constructors that are common be generic, so that it's
possible to construct expression variables from generic places (like the ABI and
ValueObject) without having to know the specifics about the class.

Sean Callanan 8f1f9a1be3 Now persistent expression data no longer lives with the Target, but rather with
the corresponding TypeSystem.  This makes sense because what kind of data there
is -- and how it can be looked up -- depends on the language.

Functionality that is common to all type systems is factored out into
PersistentExpressionState.

There are still a bunch of dependencies on the plug-in, but this helps to

There are also a few more bits we need to move (and abstract, for example the
ClangPersistentVariables).

Sean Callanan 3820e9cd17 ExpressionVariable now uses llvm::cast() instead of As...() for RTTI.
As part of our overall switch from hand-rolling RTTI to using LLVM-compatible
methods, I've done the same for ExpressionVariable.  The main documentation for
how to do this is in TypeSystem.h, so I've simply referred to that.

Sean Callanan 30e339749f Jim told me about a cleaner way to include headers from plug-ins.
This is still something I need to fix, but at least it's not so ugly, and it's
consistent with the other code that does that so we will catch it when we purge
all such code.

Sean Callanan e33724f371 In preparation for factoring persistent variables into a generic part and a
Clang-specific part, create the ExpressionVariable source/header file and
move ClangExpressionVariable into the Clang expression parser plugin.

It is expected that there are some ugly #include paths... these will be resolved
by either (1) making that code use generic expression variables (once they're
separated appropriately) or (2) moving that code into a plug-in, often
the expression parser plug-in.

Greg Clayton 99558cc424 Final bit of type system cleanup that abstracts declaration contexts into lldb_private::CompilerDeclContext and renames ClangType to CompilerType in many accessors and functions.
Create a new "lldb_private::CompilerDeclContext" class that will replace all direct uses of "clang::DeclContext" when used in compiler agnostic code, yet still allow for conversion to clang::DeclContext subclasses by clang specific code. This completes the abstraction of type parsing by removing all "clang::" references from the SymbolFileDWARF. The new "lldb_private::CompilerDeclContext" class abstracts decl contexts found in compiler type systems so they can be used in internal API calls. The TypeSystem is required to support CompilerDeclContexts with new pure virtual functions that start with "DeclContext" in the member function names. Converted all code that used lldb_private::ClangNamespaceDecl over to use the new CompilerDeclContext class and removed the ClangNamespaceDecl.cpp and ClangNamespaceDecl.h files.

Removed direct use of clang APIs from SBType and now use the abstract type systems to correctly explore types.

Bulk renames for things that used to return a ClangASTType which is now CompilerType:

    "Type::GetClangFullType()" to "Type::GetFullCompilerType()"
    "Type::GetClangLayoutType()" to "Type::GetLayoutCompilerType()"
    "Type::GetClangForwardType()" to "Type::GetForwardCompilerType()"
    "Value::GetClangType()" to "Value::GetCompilerType()"
    "Value::SetClangType (const CompilerType &)" to "Value::SetCompilerType (const CompilerType &)"
    "ValueObject::GetClangType ()" to "ValueObject::GetCompilerType()"
    many more renames that are similar.
