Implement SBTarget::CreateValueFromAddress() with a behavior equivalent to SBValue::CreateValueFromAddress()
(but without the need to grab an SBValue first just as a starting point to make up another SBValue out of whole cloth)

Richard Mitton f86248d9ba Added a 'jump' command, similar to GDBs.
This allows the PC to be directly changed to a different line.
It's similar to the example python script in examples/python/jump.py, except implemented as a builtin.

Also this version will track the current function correctly even if the target line resolves to multiple addresses. (e.g. debugging a templated function)

Jason Molenda c7e828eef1 Don't recommend using bytearray(buf, 'ascii') for binary data read with
SBProcess::ReadMemory - it will fail for anything with the high bit set.

Greg Clayton 226cce2511 Added a way to extract the module specifications from a file. A module specification is information that is required to describe a module (executable, shared library, object file, ect). This information includes host path, platform path (remote path), symbol file path, UUID, object name (for objects in .a files for example you could have an object name of "foo.o"), and target triple. Module specification can be used to create a module, or used to add a module to a target. A list of module specifications can be used to enumerate objects in container objects (like universal mach files and BSD archive files).
There are two new classes:

lldb::SBModuleSpec
lldb::SBModuleSpecList

The SBModuleSpec wraps up a lldb_private::ModuleSpec, and SBModuleSpecList wraps up a lldb_private::ModuleSpecList.

The semi-unofficial way of returning a status from a Python command was to return a string (e.g. return "no such variable was found") that LLDB would pick as a clue of an error having happened

This checkin changes that:
- SBCommandReturnObject now exports a SetError() call, which can take an SBError or a plain C-string
- script commands now drop any return value and expect the SBCommandReturnObject ("return object") to be filled in appropriately - if you do nothing, a success will be assumed

If your commands were relying on returning a value and having LLDB pick that up as an error, please change your commands to SetError() through the return object or expect changes in behavior

Greg Clayton d8c3d4b1e9 Implemented a types.py module that allows types to be inspected for padding.
The script was able to point out and save 40 bytes in each lldb_private::Section by being very careful where we need to have virtual destructors and also by re-ordering members.

Greg Clayton 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.

Enrico Granata e34ade7986 Improvements to the data formatters SB API:
- exposing new accessors: formats/format, ..., that allow you to iterate over all formatters
 e.g. sys_category = lldb.debugger.GetCategory("system").summary['char *']
- ensuring that C++-based synthetic children provider can at least print their description accurately, if nothing else

Enrico Granata b0c72d99dc <rdar://problem/13646047>
Providing a Python helper SBData.CreateDataFromInt() to make an SBData out of a single integer number
It tries to use the current target, if any, for endianness and pointer size, and it picks a reasonable size on your behalf - if there is no way it can infer anything reasonable it essentially picks a 64-bit Mac as the reference model

SWIG is smart enough to recognize that C++ operators == and != mean __eq__ and __ne__ in Python and do the appropriate translation
But it is not smart enough to recognize that mySBObject == None should return False instead of erroring out
The %pythoncode blocks are meant to provide those extra smarts (and they play some SWIG&Python magic to find the right function to call behind the scenes with no risk of typos :-)
Lastly, SBBreakpoint provides an == but never provided a != operator - common courtesy is to provide both

Greg Clayton 7b0992d9cd After discussing with Chris Lattner, we require C++11, so lets get rid of the macros and just use C++11.
llvm-svn: 179805
2013-04-18 22:45:39 +00:00
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.

Enrico Granata f15ee4e89f <rdar://problem/13563628>
Introducing a negative cache for ObjCLanguageRuntime::LookupInCompleteClassCache()
This helps speed up the (common) case of us looking for classes that are hidden deep within Cocoa internals and repeatedly failing at finding type information for them.
In order for this to work, we need to clean this cache whenever debug information is added. A new symbols loaded event is added that is triggered with add-dsym (before modules loaded would be triggered for both adding modules and adding symbols).
Interested parties can register for this event. Internally, we make sure to clean the negative cache whenever symbols are added.
Lastly, ClassDescriptor::IsTagged() has been refactored to GetTaggedPointerInfo() that also (optionally) returns info and value bits. In this way, data formatters can share tagged pointer code instead of duplicating the required arithmetic.

Enrico Granata ceba071330 - Masking out SBCommandReturnObject::Printf() from the Python layer because SWIG and varargs do not get along well.
It is replaced by a Print("str") call which is equivalent to Printf("%s","str")
