4069730c75 Testcase and fix for bug 24074
Summary:
In bug 24074, the type information is not shown
correctly. This commit includes the following -
-> Changes for displaying correct type based on
current lexical scope for the command "image
lookup -t"

-> The corresponding testcase.

-> This patch was reverted due to segfaults in
FreeBSD and Mac, I fixed the problems for both now.

2bd8e7b644 Fix the TestCppNsImport test case for DWARF. It was failing for DWARF in .o files because SymbolFileDWARFDebugMap didn't implement the following function:
void
ParseDeclsForContext (lldb_private::CompilerDeclContext decl_ctx) override;
                   
Now it does and the test works.

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).

cebabb9fc0 DWARFASTParserClang::CompleteTypeFromDWARF: Handle incomplete baseclass or child
Summary:
With this change DWARFASTParserClang::CompleteTypeFromDWARF returns false if
DWARFASTParserClang::ParseChildMembers returns false. Similarly, it returns
false if any base class is of an incomplete type. This helps in cases like
these:

  class Foo
  {
  public:
    std::string str;
  };
  ...
  Foo f;

If a file with the above code is compiled with a modern clang but without
the -fno-limit-debug-info (or similar) option, then the DWARF has only
a forward declration for std::string. In which case, the type for
"class Foo" cannot be completed. If LLDB does not detect that a child
member has incomplete type, then it wrongly conveys to clang (the LLDB
compiler) that "class Foo" is complete, and consequently crashes due to
an assertion failure in clang when running commands like "p f" or
"frame var f".

56939cb310 TypeSystem is now a plugin interface and removed any "ClangASTContext &Class::GetClangASTContext()" functions.
This cleans up type systems to be more pluggable. Prior to this we had issues:
- Module, SymbolFile, and many others has "ClangASTContext &GetClangASTContext()" functions. All have been switched over to use "TypeSystem *GetTypeSystemForLanguage()"
- Cleaned up any places that were using the GetClangASTContext() functions to use TypeSystem
- Cleaned up Module so that it no longer has dedicated type system member variables:
    lldb::ClangASTContextUP     m_ast;          ///< The Clang AST context for this module.
    lldb::GoASTContextUP        m_go_ast;       ///< The Go AST context for this module.
    
    Now we have a type system map:
    
    typedef std::map<lldb::LanguageType, lldb::TypeSystemSP> TypeSystemMap;
    TypeSystemMap               m_type_system_map;    ///< A map of any type systems associated with this module
- Many places in code were using ClangASTContext static functions to place with CompilerType objects and add modifiers (const, volatile, restrict) and to make typedefs, L and R value references and more. These have been made into CompilerType functions that are abstract:

    class CompilerType
    {
    ...
    
    //----------------------------------------------------------------------
    // Return a new CompilerType that is a L value reference to this type if
    // this type is valid and the type system supports L value references,
    // else return an invalid type.
    //----------------------------------------------------------------------
    CompilerType
    GetLValueReferenceType () const;

    //----------------------------------------------------------------------
    // Return a new CompilerType that is a R value reference to this type if
    // this type is valid and the type system supports R value references,
    // else return an invalid type.
    //----------------------------------------------------------------------
    CompilerType
    GetRValueReferenceType () const;

    //----------------------------------------------------------------------
    // Return a new CompilerType adds a const modifier to this type if
    // this type is valid and the type system supports const modifiers,
    // else return an invalid type.
    //----------------------------------------------------------------------
    CompilerType
    AddConstModifier () const;

    //----------------------------------------------------------------------
    // Return a new CompilerType adds a volatile modifier to this type if
    // this type is valid and the type system supports volatile modifiers,
    // else return an invalid type.
    //----------------------------------------------------------------------
    CompilerType
    AddVolatileModifier () const;

    //----------------------------------------------------------------------
    // Return a new CompilerType adds a restrict modifier to this type if
    // this type is valid and the type system supports restrict modifiers,
    // else return an invalid type.
    //----------------------------------------------------------------------
    CompilerType
    AddRestrictModifier () const;

    //----------------------------------------------------------------------
    // Create a typedef to this type using "name" as the name of the typedef
    // this type is valid and the type system supports typedefs, else return
    // an invalid type.
    //----------------------------------------------------------------------
    CompilerType
    CreateTypedef (const char *name, const CompilerDeclContext &decl_ctx) const;
    
    };
    
Other changes include:
- Removed "CompilerType TypeSystem::GetIntTypeFromBitSize(...)" and CompilerType TypeSystem::GetFloatTypeFromBitSize(...) and replaced it with "CompilerType TypeSystem::GetBuiltinTypeForEncodingAndBitSize(lldb::Encoding encoding, size_t bit_size);"
- Fixed code in Type.h to not request the full type for a type for no good reason, just request the forward type and let the type expand as needed

f73034f99a Use LLVM casting for TypeSystem so you can cast it to subclasses.
This will keep our code cleaner and it removes the need for intrusive additions to TypeSystem like:

class TypeSystem
{
    virtual ClangASTContext *
    AsClangASTContext() = 0;
}

As you can now just use the llvm::dyn_cast and other casts.

261ac3f4b5 Made a new abstract class named "DWARFASTParser" which lives in "source/Plugins/SymbolFile/DWARF":
class DWARFASTParser
{
public:
    virtual ~DWARFASTParser() {}

    virtual lldb::TypeSP
    ParseTypeFromDWARF (const lldb_private::SymbolContext& sc,
                        const DWARFDIE &die,
                        lldb_private::Log *log,
                        bool *type_is_new_ptr) = 0;


    virtual lldb_private::Function *
    ParseFunctionFromDWARF (const lldb_private::SymbolContext& sc,
                            const DWARFDIE &die) = 0;

    virtual bool
    CompleteTypeFromDWARF (const DWARFDIE &die,
                           lldb_private::Type *type,
                           lldb_private::CompilerType &clang_type) = 0;

    virtual lldb_private::CompilerDeclContext
    GetDeclContextForUIDFromDWARF (const DWARFDIE &die) = 0;

    virtual lldb_private::CompilerDeclContext
    GetDeclContextContainingUIDFromDWARF (const DWARFDIE &die) = 0;

};

We have one subclass named DWARFASTParserClang that implements all of the clang specific AST type parsing. This keeps all DWARF parsing in the DWARF plug-in. Moved all of the DWARF parsing code that was in ClangASTContext over into DWARFASTParserClang.

lldb_private::TypeSystem classes no longer have any DWARF parsing functions in them, but they can hand out a DWARFASTParser:

virtual DWARFASTParser *
GetDWARFParser ()
{
    return nullptr;
}

This keeps things clean and makes for easy merging when we have different AST's for different languages.

6071e6fc94 Major DWARF cleanup.
Added a new class called DWARFDIE that contains a DWARFCompileUnit and DWARFDebugInfoEntry so that these items always stay together.

There were many places where we just handed out DWARFDebugInfoEntry pointers and then use them with a compile unit that may or may not be the correct one. Clients outside of DWARFCompileUnit and DWARFDebugInfoEntry should all be dealing with DWARFDIE instances instead of playing with DWARFCompileUnit/DWARFDebugInfoEntry pairs manually.

This paves to the way for some modifications that are coming for DWO.

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.
