figure it out through the ObjectFile.
Background: dyld binaries often have extra symbols in their symbol table like "malloc" and "free" for the early bringup of dyld and we often don't want to set breakpoints in dynamic linker binaries. We also don't want to call the "malloc" or "free" function in dyld when a user writes an expression like "(void *)malloc(123)" so we need to avoid doing name lookups in dyld. We mark Modules as being dynamic link editors and this helps do correct lookups for breakpoints by name and function lookups.

apps and binaries.
Changes include:
- ObjectFileMachO can now determine if a binary is "*-apple-ios" or "*-apple-macosx" by checking the min OS and SDK load commands
- ArchSpec now says "<arch>-apple-macosx" is equivalent to "<arch>-apple-ios" since the simulator mixes and matches binaries (some from the system and most from the iOS SDK).
- Getting process inforamtion on MacOSX now correctly classifies iOS simulator processes so they have "*-apple-ios" architectures in the ProcessInstanceInfo
- PlatformiOSSimulator can now list iOS simulator processes correctly instead of showing nothing by using:
(lldb) platform select ios-simulator
(lldb) platform process list
- debugserver can now properly return "*-apple-ios" for the triple in the process info packets for iOS simulator executables
- GDBRemoteCommunicationClient now correctly passes along the triples it gets for process info by setting the OS in the llvm::Triple correctly

ObjectFile::SetLoadAddress (Target &target,
lldb::addr_t value,
bool value_is_offset);
Now "value" is a slide if "value_is_offset" is true, and "value" is an image base address otherwise. All previous usage of this API was using slides.
Updated the ObjectFileELF and ObjectFileMachO SetLoadAddress methods to do the right thing.
Also updated the ObjectFileMachO::SetLoadAddress() function to not load __LINKEDIT when it isn't needed and to only load sections that belong to the executable object file.

- 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)

<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.

ObjectFile. This is designed to be used when you have an object file that contains one or more architectures (MacOSX universal (fat) files) and/or one or more objects (BSD archive (.a files)).
There is a new static ObjectFile function you can call:
size_t
ObjectFile::GetModuleSpecifications (const FileSpec &file,
lldb::offset_t file_offset,
ModuleSpecList &specs)
This will fill in "specs" which the details of all the module specs (file + arch + UUID (if there is one) + object name (for BSD archive objects eventually) + file offset to the object in question).
This helps us when a user specifies a file that contains a single architecture, and also helps us when we are given a debug symbol file (like a dSYM file on MacOSX) that contains one or more architectures and we need to be able to match it up to an existing Module that has no debug info.

DWARF with .o files now uses 40-60% less memory!
Big fixes include:
- Change line table internal representation to contain "file addresses". Since each line table is owned by a compile unit that is owned by a module, it makes address translation into lldb_private::Address easy to do when needed.
- Removed linked address members/methods from lldb_private::Section and lldb_private::Address
- lldb_private::LineTable can now relink itself using a FileRangeMap to make it easier to re-link line tables in the future
- Added ObjectFile::ClearSymtab() so that we can get rid of the object file symbol tables after we parse them once since they are not needed and kept memory allocated for no reason
- Moved the m_sections_ap (std::auto_ptr to section list) and m_symtab_ap (std::auto_ptr to the lldb_private::Symtab) out of each of the ObjectFile subclasses and put it into lldb_private::ObjectFile.
- Changed how the debug map is parsed and stored to be able to:
- Lazily parse the debug map for each object file
- not require the address map for a .o file until debug information is linked for a .o file

lldb was mmap'ing archive files once per .o file it loads, now it correctly shares the archive between modules.
LLDB was also always mapping entire contents of universal mach-o files, now it maps just the slice that is required.
Added a new logging channel for "lldb" called "mmap" to help track future regressions.
Modified the ObjectFile and ObjectContainer plugin interfaces to take a data offset along with the file offset and size so we can implement the correct caching and efficient reading of parts of files without mmap'ing the entire file like we used to.
The current implementation still keeps entire .a files mmaped (once) and entire slices from universal files mmaped to ensure that if a client builds their binaries during a debug session we don't lose our data and get corrupt object file info and debug info.

Major fixed to allow reading files that are over 4GB. The main problems were that the DataExtractor was using 32 bit offsets as a data cursor, and since we mmap all of our object files we could run into cases where if we had a very large core file that was over 4GB, we were running into the 4GB boundary.
So I defined a new "lldb::offset_t" which should be used for all file offsets.
After making this change, I enabled warnings for data loss and for enexpected implicit conversions temporarily and found a ton of things that I fixed.
Any functions that take an index internally, should use "size_t" for any indexes and also should return "size_t" for any sizes of collections.

Simplify the locking strategy for Module and its owned objects to always use the Module's mutex to avoid A/B deadlocks. We had a case where a symbol vendor was locking itself and then calling a function that would try to get it's Module's mutex and at the same time another thread had the Module mutex that was trying to get the SymbolVendor mutex. Now any classes that inherit from ModuleChild should use the module lock using code like:
void
ModuleChildSubclass::Function
{
ModuleSP module_sp(GetModule());
if (module_sp)
{
lldb_private::Mutex::Locker locker(module_sp->GetMutex());
... do work here...
}
}
This will help avoid deadlocks by using as few locks as possible for a module and all its child objects and also enforce detecting if a module has gone away (the ModuleSP will be returned empty if the weak_ptr does refer to a valid object anymore).

I started work on being able to add symbol files after a debug session
had started with a new "target symfile add" command and quickly ran into
problems with stale Address objects in breakpoint locations that had
lldb_private::Section pointers into modules that had been removed or
replaced. This also let to grabbing stale modules from those sections.
So I needed to thread harded the Address, Section and related objects.
To do this I modified the ModuleChild class to now require a ModuleSP
on initialization so that a weak reference can created. I also changed
all places that were handing out "Section *" to have them hand out SectionSP.
All ObjectFile, SymbolFile and SymbolVendors were inheriting from ModuleChild
so all of the find plug-in, static creation function and constructors now
require ModuleSP references instead of Module *.
Address objects now have weak references to their sections which can
safely go stale when a module gets destructed.
This checkin doesn't complete the "target symfile add" command, but it
does get us a lot clioser to being able to do such things without a high
risk of crashing or memory corruption.

user space programs. The core file support is implemented by making a process
plug-in that will dress up the threads and stack frames by using the core file
memory.
Added many default implementations for the lldb_private::Process functions so
that plug-ins like the ProcessMachCore don't need to override many many
functions only to have to return an error.
Added new virtual functions to the ObjectFile class for extracting the frozen
thread states that might be stored in object files. The default implementations
return no thread information, but any platforms that support core files that
contain frozen thread states (like mach-o) can make a module using the core
file and then extract the information. The object files can enumerate the
threads and also provide the register state for each thread. Since each object
file knows how the thread registers are stored, they are responsible for
creating a suitable register context that can be used by the core file threads.
Changed the process CreateInstace callbacks to return a shared pointer and
to also take an "const FileSpec *core_file" parameter to allow for core file
support. This will also allow for lldb_private::Process subclasses to be made
that could load crash logs. This should be possible on darwin where the crash
logs contain all of the stack frames for all of the threads, yet the crash
logs only contain the registers for the crashed thrad. It should also allow
some variables to be viewed for the thread that crashed.

Fixed "target modules list" (aliased to "image list") to output more information
by default. Modified the "target modules list" to have a few new options:
"--header" or "-h" => show the image header address
"--offset" or "-o" => show the image header address offset from the address in the file (the slide applied to the shared library)
Removed the "--symfile-basename" or "-S" option, and repurposed it to
"--symfile-unique" "-S" which will show the symbol file if it differs from
the executable file.
ObjectFile's can now be loaded from memory for cases where we don't have the
files cached locally in an SDK or net mounted root. ObjectFileMachO can now
read mach files from memory.
Moved the section data reading code into the ObjectFile so that the object
file can get the section data from Process memory if the file is only in
memory.
lldb_private::Module can now load its object file in a target with a rigid
slide (very common operation for most dynamic linkers) by using:
bool
Module::SetLoadAddress (Target &target, lldb::addr_t offset, bool &changed)
lldb::SBModule() now has a new constructor in the public interface:
SBModule::SBModule (lldb::SBProcess &process, lldb::addr_t header_addr);
This will find an appropriate ObjectFile plug-in to load an image from memory
where the object file header is at "header_addr".

mmap() the entire object file contents into memory with MAP_PRIVATE.
We do this because object file contents can change on us and currently
this helps alleviate this situation. It also make the code for accessing
object file data much easier to manage and we don't end up opening the
file, reading some data and closing the file over and over.

platform status -- gets status information for the selected platform
platform create <platform-name> -- creates a new instance of a remote platform
platform list -- list all available platforms
platform select -- select a platform instance as the current platform (not working yet)
When using "platform create" it will create a remote platform and make it the
selected platform. For instances for iPhone OS debugging on Mac OS X one can
do:
(lldb) platform create remote-ios --sdk-version=4.0
Remote platform: iOS platform
SDK version: 4.0
SDK path: "/Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.0"
Not connected to a remote device.
(lldb) file ~/Documents/a.out
Current executable set to '~/Documents/a.out' (armv6).
(lldb) image list
[ 0] /Volumes/work/gclayton/Documents/devb/attach/a.out
[ 1] /Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.0/Symbols/usr/lib/dyld
[ 2] /Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.0/Symbols/usr/lib/libSystem.B.dylib
Note that this is all happening prior to running _or_ connecting to a remote
platform. Once connected to a remote platform the OS version might change which
means we will need to update our dependecies. Also once we run, we will need
to match up the actualy binaries with the actualy UUID's to files in the
SDK, or download and cache them locally.
This is just the start of the remote platforms, but this modification is the
first iteration in getting the platforms really doing something.

an interface to a local or remote debugging platform. By default each host OS
that supports LLDB should be registering a "default" platform that will be
used unless a new platform is selected. Platforms are responsible for things
such as:
- getting process information by name or by processs ID
- finding platform files. This is useful for remote debugging where there is
an SDK with files that might already or need to be cached for debug access.
- getting a list of platform supported architectures in the exact order they
should be selected. This helps the native x86 platform on MacOSX select the
correct x86_64/i386 slice from universal binaries.
- Connect to remote platforms for remote debugging
- Resolving an executable including finding an executable inside platform
specific bundles (macosx uses .app bundles that contain files) and also
selecting the appropriate slice of universal files for a given platform.
So by default there is always a local platform, but remote platforms can be
connected to. I will soon be adding a new "platform" command that will support
the following commands:
(lldb) platform connect --name machine1 macosx connect://host:port
Connected to "machine1" platform.
(lldb) platform disconnect macosx
This allows LLDB to be well setup to do remote debugging and also once
connected process listing and finding for things like:
(lldb) process attach --name x<TAB>
The currently selected platform plug-in can now auto complete any available
processes that start with "x". The responsibilities for the platform plug-in
will soon grow and expand.
