Saleem Abdulrasool ba507b04e1 Silence -Wqual-cast warnings from GCC 5.2
There were a number of const qualifiers being cast away which caused warnings.
This cluttered the output hiding real errors.  Silence them by explicit casting.

Todd Fiala 7df337f85c ArchSpec: fix unintentional promotion of unspecified unknowns to specified unknowns
* ArchSpec::MergeFrom() would erroneously promote an unspecified
  unknown to a specified unknown when both the ArchSpec and the merged
  in ArchSpec were both unspecified unknowns. This no longer happens,
  which fixes issues with global module cache lookup in some
  situations.

* Added ArchSpec::DumpTriple(Stream&) that now properly prints
  unspecified unknowns as '*' and specified unknows as 'unknown'.
  This makes it trivial to tell the difference between the two.
  Converted printing code over ot using DumpTriple() rather than
  building from scratch.

* Fixed up a couple places that were not guaranteeing that an
  unspecified unknown was recorded as such.

Enrico Granata 9b0af1b86f Add a 'type lookup' command. This command is meant to look up type information by name in a language-specific way.
Currently, it only supports Objective-C - C++ types can be looked up through debug info via 'image lookup -t', whereas ObjC types via this command are looked up by runtime introspection

This behavior is in line with type lookup's behavior in Xcode 7, but I am definitely open to feedback as to what makes the most sense here

Greg Clayton 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

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.

Dawn Perchik 009d110de4 Set the default language to use when evaluating to that of the frame's CU.
* Use the frame's context (instead of just the target's) when evaluating,
  so that the language of the frame's CU can be used to select the
  compiler and/or compiler options to use when parsing the expression.
  This allows for modules built with mixed languages to be parsed in
  the context of their frame. 
* Add all C and C++ language variants when determining the language options
  to set.
* Enable C++ language options when language is C or ObjC as a workaround since
  the expression parser uses features of C++ to capture values.
* Enable ObjC language options when language is C++ as a workaround for ObjC
  requirements.
* Disable C++11 language options when language is C++03.
* Add test TestMixedLanguages.py to check that the language being used
  for evaluation is that of the frame.
* Fix test TestExprOptions.py to check for C++11 instead of C++ since C++ has
  to be enabled for C, and remove redundant expr --language test for ObjC.
* Fix TestPersistentPtrUpdate.py to not require C++11 in C.

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 &)"

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.

Zachary Turner 1124045ac7 Don't #include "lldb-python.h" from anywhere.
Since interaction with the python interpreter is moving towards
being more isolated, we won't be able to include this header from
normal files anymore, all includes of it should be localized to
the python library which will live under source/bindings/API/Python
after a future patch.

None of the files that were including this header actually depended
on it anyway, so it was just a dead include in every single instance.

Pavel Labath 4446487d71 Improve LLDB prompt handling
Summary:
There is an issue in lldb where the command prompt can appear at the wrong time. The partial fix
we have in for this is not working all the time and is introducing unnecessary delays. This
change does:
- Change Process:SyncIOHandler to use integer start id's for synchronization to avoid it being
  confused by quick start-stop cycles. I picked this up from a suggested patch by Greg to
  lldb-dev.
- coordinates printing of asynchronous text with the iohandlers. This is also based on a
  (different) Greg's patch, but I have added stronger synchronization to it to avoid races.

Together, these changes solve the prompt problem for me on linux (both with and without libedit).
I think they should behave similarly on Mac and FreeBSD and I think they will not make matters
worse for windows.

Test Plan: Prompt comes out alright. All tests still pass on linux.

Summary:
 
This patch is the beginnings of support for Non-stop mode in the remote protocol. Letting a user examine stopped threads, while other threads execute freely.

Non-stop mode is enabled using the setting target.non-stop-mode, which sends a QNonStop packet when establishing the remote connection.
Changes are also made to treat the '?' stop reply packet differently in non-stop mode, according to spec https://sourceware.org/gdb/current/onlinedocs/gdb/Remote-Non_002dStop.html#Remote-Non_002dStop.
A setting for querying the remote for default thread on setup is also included.

Handling of '%' async notification packets will be added next.

This change doesn't actually make that work, the part where we
extract the thrown object type from the throw site isn't done yet.

This provides a general programmatic "precondition" that you can add

callbacks.

Jason Molenda ede3193bbd Add a "force_kill" arg to Process::Destroy(). This is needed after
the changes in r233255/r233258.  Normally if lldb attaches to
a running process, when we call Process::Destroy, we want to detach
from the process.  If lldb launched the process itself, ::Destroy
should kill it.

However, if we attach to a process and the driver calls SBProcess::Kill()
(which calls Destroy), we need to kill it even if we didn't launch it
originally.

The force_kill param allows for the SBProcess::Kill method to force the
behavior of Destroy.

Zachary Turner 0641ca1a2d Remove ScriptInterpreterObject.
This removes ScriptInterpreterObject from the codebase completely.
Places that used to rely on ScriptInterpreterObject now use
StructuredData::Object and its derived classes.  To support this,
a new type of StructuredData object is introduced, called
StructuredData::Generic, which stores a void*.  Internally within
the python library, StructuredPythonObject subclasses this
StructuredData::Generic class so that it can addref and decref
the python object on construction and destruction.

Additionally, all of the classes in PythonDataObjects.h such
as PythonList, PythonDictionary, etc now provide a method to
create an instance of the corresponding StructuredData type.  For
example, there is PythonDictionary::CreateStructuredDictionary.
To eliminate dependencies on PythonDataObjects for external
callers, all ScriptInterpreter methods now return only
StructuredData classes

The rest of the changes in this CL are focused on fixing up
users of PythonDataObjects classes to use the new StructuredData
classes.

Pavel Labath 00b7f95b12 Fix handling of backslashes in Args parsing
Summary:
Presently Args::SetCommandString allows quotes to be escaped with backslash. However, the
backslash itself is not removed from the argument, nor there is a way to escape the backslash
itself. This leads to surprising results:

"a b" c"   -> 'a b', 'c'  # Here we actually have an unterminated quote, but that is ignored
"a b\" c"  -> 'a b\" c'   # We try to escape the quote. That works but the backslash is not removed.
"a b\\" c" -> 'a b\\" c'  # Escaping the backslash has no effect.

This change changes quote handling to be more shell-like:
- single quotes and backquotes are literal and there is no way to escape the closing quote or
  anything else inside;
- inside double quotes you can use backslash to escape the closing quote and another backslash
- outside any quotes, you can use backslash to escape quotes, spaces and itself.

This makes the parsing more consistent with what the user is familiar and increases the
probability that pasting the command line from shell to the "process launch" command "just work".

Pavel Labath df50f9440d Handle trailing spaces on "settings set" command more correctly
Summary:
Currently we have some settings which treat "\ " on settings set commands specially. E.g., it is
a valid way of specifying an argument of " " to a target. However, this fails if "\ " is the last
argument as CommandObjectSettingsSet strips trailing whitespace. This resulted in a surprising
argument of "\" to the target.

This patch disables the training whitespace removal at a global
level. Instead, for each argument type we locally determine whether whitespace stripping makes
sense. Currently, I strip whitespace for all simple object type except of regex and
format-string, with the rationale that these two object types do their own complex parsing and we
want to interfere with them as least as possible. Specifically, stripping the whitespace of a
regex "\ " will result in a (surprising?) error "trailing backslash". Furthermore, the default
value of dissasembly-format setting already contains a trailing space and there is no way for the
user to type this in manually if we strip whitespace.
