9076c0fffb Made all other "operator bool"s explicit and ensured
that all clients use them explicitly.  This will hopefully
prevent any future confusion where things get cast to types
we don't expect.

ddd7a2a65b Changed the bool conversion operator on ConstString
to be explicit, to prevent horrid things like

std::string a = ConstString("foo")

from taking the path ConstString -> bool -> char
-> std::string.

This fixes, among other things, ClangFunction.

52694e3bb8 <rdar://problem/15001220>
Fixed an issue with the lldb/test/lang/cpp/virtual test case had a virtual class that had a DW_TAG_inheritance child that was virtual and had a DW_AT_data_member_location of:

DW_AT_data_member_location( DW_OP_dup, DW_OP_deref, DW_OP_constu(0x00000018), DW_OP_minus, DW_OP_deref, DW_OP_plus )

We failed to evaluate this and then we were passing the incorrect offset back to clang and clang would crash. The AST external source has a function named LayoutRecordType which allows us to supply the virtual base class offsets, but that really doesn't make sense to do as clang will lay them out correctly. So we must ignore virtual base classes when doing layout.

109f86860a Fix issues with GCC debugging. GCC emits DWARF in unique ways that LLDB wasn't handling. This fix will fix cases where classes are forward declared using DW_TAG_structure_type and then actually defined using DW_TAG_class_type. LLDB, when it finds a forward declaration, would try and find and parse the complete type. It does this by:
1 - looking up the type basename in the type index
2 - iterate through all matches and look for decl contexts (namespace/class hierarchy) that match

The issue was the decl context matching wasn't watching for DW_TAG_class_type/DW_TAG_structure_type mismatches, and it wasn't also getting the name for DIE's that didn't have a DW_AT_name, but did have a DW_AT_specification that had a name.

57ee306789 Huge change to clean up types.
A long time ago we start with clang types that were created by the symbol files and there were many functions in lldb_private::ClangASTContext that helped. Later we create ClangASTType which contains a clang::ASTContext and an opauque QualType, but we didn't switch over to fully using it. There were a lot of places where we would pass around a raw clang_type_t and also pass along a clang::ASTContext separately. This left room for error.

This checkin change all type code over to use ClangASTType everywhere and I cleaned up the interfaces quite a bit. Any code that was in ClangASTContext that was type related, was moved over into ClangASTType. All code that used these types was switched over to use all of the new goodness.

3046e66830 Cleanup on the unified section list changes. Main changes are:
- ObjectFile::GetSymtab() and ObjectFile::ClearSymtab() no longer takes any flags
- Module coordinates with the object files and contain a unified section list so that object file and symbol file can share sections when they need to, yet contain their own sections.

Other cleanups:
- Fixed Symbol::GetByteSize() to not have the symbol table compute the byte sizes on the fly
- Modified the ObjectFileMachO class to compute symbol sizes all at once efficiently
- Modified the Symtab class to store a file address lookup table for more efficient lookups
- Removed Section::Finalize() and SectionList::Finalize() as they did nothing
- Improved performance of the detection of symbol files that have debug maps by excluding stripped files and core files, debug files, object files and stubs
- Added the ability to tell if an ObjectFile has been stripped with ObjectFile::IsStripped() (used this for the above performance improvement)

f02500c74c Added the ability to get a list of types from a SBModule or SBCompileUnit. Sebastien Metrot wanted this, and sent a hollowed out patch. I filled in the blanks and did the low level implementation. The new functions are:
//------------------------------------------------------------------
/// Get all types matching \a type_mask from debug info in this
/// module.
///
/// @param[in] type_mask
///     A bitfield that consists of one or more bits logically OR'ed
///     together from the lldb::TypeClass enumeration. This allows
///     you to request only structure types, or only class, struct
///     and union types. Passing in lldb::eTypeClassAny will return
///     all types found in the debug information for this module.
///
/// @return
///     A list of types in this module that match \a type_mask
//------------------------------------------------------------------
lldb::SBTypeList
SBModule::GetTypes (uint32_t type_mask)


//------------------------------------------------------------------
/// Get all types matching \a type_mask from debug info in this
/// compile unit.
///
/// @param[in] type_mask
///    A bitfield that consists of one or more bits logically OR'ed
///    together from the lldb::TypeClass enumeration. This allows
///    you to request only structure types, or only class, struct
///    and union types. Passing in lldb::eTypeClassAny will return
///    all types found in the debug information for this compile
///    unit.
///
/// @return
///    A list of types in this compile unit that match \a type_mask
//------------------------------------------------------------------
lldb::SBTypeList
SBCompileUnit::GetTypes (uint32_t type_mask = lldb::eTypeClassAny);

This lets you request types by filling out a mask that contains one or more bits from the lldb::TypeClass enumerations, so you can only get the types you really want.

<rdar://problem/13594769>

Main changes in this patch include:
- cleanup plug-in interface and use ConstStrings for plug-in names
- Modfiied the BSD Archive plug-in to be able to pick out the correct .o file when .a files contain multiple .o files with the same name by using the timestamp
- Modified SymbolFileDWARFDebugMap to properly verify the timestamp on .o files it loads to ensure we don't load updated .o files and cause problems when debugging

The plug-in interface changes:

Modified the lldb_private::PluginInterface class that all plug-ins inherit from:

Changed:

virtual const char * GetPluginName() = 0;

To: 

virtual ConstString GetPluginName() = 0;

Removed:

virtual const char * GetShortPluginName() = 0;

- Fixed up all plug-in to adhere to the new interface and to return lldb_private::ConstString values for the plug-in names. 
- Fixed all plug-ins to return simple names with no prefixes. Some plug-ins had prefixes and most ones didn't, so now they all don't have prefixed names, just simple names like "linux", "gdb-remote", etc.

b5ad4ec7a3 Cleanup logging to use the new "std::string FileSpec::GetPath()" function. Also added a similar function for modules:
std::string
Module::GetSpecificationDescription () const;

This returns the module as "/usr/lib/libfoo.dylib" for normal files (calls "std::string FileSpec::GetPath()" on m_file) but it also might include the object name in case the module is for a .o file in a BSD archive ("/usr/lib/libfoo.a(bar.o)"). Cleaned up necessary logging code to use it.

283b265309 <rdar://problem/13298695>
Fixed LLDB to be able to correctly parse template parameters that have no name and no type. This can be triggered by the following LLVM/Clang code:

template <typename T, typename = void>
class SmallVectorTemplateCommon : public SmallVectorBase {

The “typename = void” was emitting DWARF with an empty DW_AT_name and no DW_AT_type. We now correctly infer that no DW_AT_type means “void” and that an empty name is ok.

This means you can now call functions on things that inherit from SmallVectorTemplateCommon.

Greg Clayton
e01e07b6e7 Since we use C++11, we should switch over to using std::unique_ptr when C++11 is being used. To do this, we follow what we have done for shared pointers and we define a STD_UNIQUE_PTR macro that can be used and it will "do the right thing". Due to some API differences in std::unique_ptr and due to the fact that we need to be able to compile without C++11, we can't use move semantics so some code needed to change so that it can compile with either C++.
Anyone wanting to use a unique_ptr or auto_ptr should now use the "STD_UNIQUE_PTR(TYPE)" macro.

Now we can:

2 - dump values that use the vector attributes ("expr $ymm0")

Make lldb_private::RegularExpression thread safe everywhere. This was done by removing the m_matches array from the lldb_private::RegularExpression class and putting it into the new lldb_private::RegularExpression::Match class. When executing a regular expression you now have the option to create a lldb_private::RegularExpression::Match object and pass a pointer in if you want to get parenthesized matching. If you don't want any matching, you pass in NULL. The lldb_private::RegularExpression::Match object is initialized with the number of matches you desire. Any matching strings are now extracted from the lldb_private::RegularExpression::Match objects. This makes the regular expression objects thread safe and as a result many more regex objects were turned into static objects that end up using a local lldb_private::RegularExpression::Match object when executing.

Symbol table function names should support lookups like symbols with debug info. 

To fix this I:
- Gutted the way FindFunctions is used, there used to be way too much smarts only in the DWARF plug-in
- Made it more efficient by chopping the name up once and using simpler queries so that SymbolFile and Symtab plug-ins don't need to do as much
- Filter the results at a higher level
- Make the lldb_private::Symtab able to chop up C++ mangled names and make as much sense out of them as possible and also be able to search by basename, fullname, method name, and selector name.
