Pavel Labath 31bcd2bddd [AppleObjCRuntime] Don't bother looking for the runtime on non-apple targets
Summary:
This short-circuits the GetObjCVersion function to avoid iterating through target modules on
non-apple targets. This function is called on every Process::IsDynamicValue call, so this
overhead is not negligible.

Sean Callanan 4dbb271fcc Moved more Clang-specific parts of the expression parser into the Clang plugin.
There are still a bunch of dependencies on the plug-in, but this helps to
identify them.
There are also a few more bits we need to move (and abstract, for example the
ClangPersistentVariables).

Enrico Granata 0b6003f3e6 Make LanguageRuntime::GetDynamicTypeAndAddress return a ValueType
For C++ and ObjC, dynamic values are always (at least somewhat) pointer-like in nature, so a ValueType of scalar is actually good enough that it could originally be hardcoded as the right choice
Other languages, might have broader notions of things that are dynamic (e.g. a language where a value type can be dynamic). In those cases, it might actually be the case that a dynamic value is a pointer-to the data, or even a host address if dynamic expression results entirely in host space are being talked about

This patch enables the language runtime to make that decision, and makes ValueObjectDynamicValue comply with it

Jim Ingham 151c032c86 This patch makes Clang-independent base classes for all the expression types that lldb currently vends.
Before we had:

ClangFunction
ClangUtilityFunction
ClangUserExpression

and code all over in lldb that explicitly made Clang-based expressions. This patch adds an Expression 
base class, and three pure virtual implementations for the Expression kinds:

FunctionCaller
UtilityFunction
UserExpression

You can request one of these expression types from the Target using the Get<ExpressionType>ForLanguage. 
The Target will then consult all the registered TypeSystem plugins, and if the type system that matches 
the language can make an expression of that kind, it will do so and return it.

Because all of the real expression types need to communicate with their ExpressionParser in a uniform way, 
I also added a ExpressionTypeSystemHelper class that expressions generically can vend, and a ClangExpressionHelper 
that encapsulates the operations that the ClangExpressionParser needs to perform on the ClangExpression types. 
Then each of the Clang* expression kinds constructs the appropriate helper to do what it needs.

The patch also fixes a wart in the UtilityFunction that to use it you had to create a parallel FunctionCaller 
to actually call the function made by the UtilityFunction. Now the UtilityFunction can be asked to vend a 
FunctionCaller that will run its function. This cleaned up a lot of boiler plate code using UtilityFunctions.

Note, in this patch all the expression types explicitly depend on the LLVM JIT and IR, and all the common 
JIT running code is in the FunctionCaller etc base classes. At some point we could also abstract that dependency 
but I don't see us adding another back end in the near term, so I'll leave that exercise till it is actually necessary.

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()"

Dawn Perchik 23b1decbe7 Add support for specifying a language to use when parsing breakpoints.
Target and breakpoints options were added:
    breakpoint set --language lang --name func
    settings set target.language pascal
These specify the Language to use when interpreting the breakpoint's
expression (note: currently only implemented for breakpoints on
identifiers).  If the breakpoint language is not set, the target.language
setting is used.
This support is required by Pascal, for example, to set breakpoint at 'ns.foo'
for function 'foo' in namespace 'ns'.
Tests on the language were also added to Module::PrepareForFunctionNameLookup
for efficiency.

Greg Clayton 358cf1ea30 Resubmitting 240466 after fixing the linux test suite failures.
A few extras were fixed

- Symbol::GetAddress() now returns an Address object, not a reference. There were places where people were accessing the address of a symbol when the symbol's value wasn't an address symbol. On MacOSX, undefined symbols have a value zero and some places where using the symbol's address and getting an absolute address of zero (since an Address object with no section and an m_offset whose value isn't LLDB_INVALID_ADDRESS is considered an absolute address). So fixing this required some changes to make sure people were getting what they expected. 
- Since some places want to access the address as a reference, I added a few new functions to symbol:
    Address &Symbol::GetAddressRef();
    const Address &Symbol::GetAddressRef() const;

Linux test suite passes just fine now.

Enrico Granata 2d061e20f6 Fix a bug where we were trying to reconstruct ivars of ObjC types from the runtime in "expression parser mode"
The expression parser mode allows UnknownAnyTy to make it all the way through, but that is bad for ivars because it means type layout fails horribly (as in, clang crashes)

This patch fixes the issue by using the "variables view mode", which masks UnknownAnyTy as empty-type, and pointer-to UnknownAnyTy as void*

This, in turn, allows LLDB to properly reconstruct ivars of IMP type in ObjC type - as per accompanying test case

Since interaction with the python interpreter is moving towards

Zachary Turner a98fac28aa Fix error introduced by changing function signatures.
Since ClangASTSource::layoutRecordType() was overriding a virtual
function in the base, this was inadvertently causing a new method
to be introduced rather than an override.  To fix this all method
signatures are changed back to taking DenseMaps, and the `override`
keyword is added to make sure this type of error doesn't happen
again.

To keep the original fix intact, which is that fields and bases
must be added in offset order, the ImportOffsetMap() function
now copies the DenseMap into a vector and then sorts the vector
on the value type (e.g. the offset) before iterating over the
sorted vector and inserting the items.

Zachary Turner 504f38da4e Fix record layout when synthesizing class types.
Prior to this patch, we would try to synthesize class types by
iterating over a DenseMap of FieldDecls and adding each one to
a CXXRecordDecl.  Since a DenseMap doesn't provide a deterministic
ordering of the elements, this would not add the fields in
FieldOffset order, but rather in some random order determined by
the memory layout of the DenseMap.

This patch fixes the issue by changing DenseMaps to vectors.  The
ability to lookup a value in the DenseMap was hardly being used,
and where it is sufficient to do a vector lookup.
