Sean Callanan 3154255fd6 This is a fix for the command option parser.
There was a generic catch-all type for path arguments
called "eArgTypePath," and a specialized version
called "eArgTypeFilename."  It turns out all the
cases where we used eArgTypePath we could have
used Filename or we explicitly meant a directory.

I changed Path to DirectoryName, made it use the
directory completer, and rationalized the uses of
Path.

<rdar://problem/12068650>

More fixes to how we handle paths that are used to create a target.

This modification centralizes the location where and how what the user specifies gets resolved. Prior to this fix, the TargetList::CreateTarget variants took a FileSpec object which meant everyone had the opportunity to resolve the path their own way. Now both CreateTarget variants take a "const char *use_exe_path" which allows the TargetList::CreateTarget to centralize where the resolving happens and "do the right thing".

LLDB changes argv[0] when debugging a symlink. Now we have the notion of argv0 in the target settings:

target.arg0 (string) = 

There is also the program argument that are separate from the first argument that have existed for a while:

target.run-args (arguments) =

When running "target create <exe>", we will place the untouched "<exe>" into target.arg0 to ensure when we run, we run with what the user typed. This has been added to the ProcessLaunchInfo and all other needed places so we always carry around the:
- resolved executable path
- argv0
- program args

Some systems may not support separating argv0 from the resolved executable path and the ProcessLaunchInfo needs to carry all of this information along so that each platform can make that decision.

Jason Molenda ccd41e55f1 Ran the sources through the compiler with -Wshadow warnings
enabled after we'd found a few bugs that were caused by shadowed
local variables; the most important issue this turned up was
a common mistake of trying to obtain a mutex lock for the scope
of a code block by doing

        Mutex::Locker(m_map_mutex);

This doesn't assign the lock object to a local variable; it is
a temporary that has its dtor called immediately.  Instead,

        Mutex::Locker locker(m_map_mutex);

does what is intended.  For some reason -Wshadow happened to
highlight these as shadowed variables.

I also fixed a few obivous and easy shadowed variable issues
across the code base but there are a couple dozen more that
should be fixed when someone has a free minute.

Greg Clayton b5f0feabae Wrapped up the work I am going to do for now for the "add-dsym" or "target symfile add" command.
We can now do:

Specify a path to a debug symbols file:
(lldb) add-dsym <path-to-dsym>

Go and download the dSYM file for the "libunc.dylib" module in your target:
(lldb) add-dsym --shlib libunc.dylib

Go and download the dSYM given a UUID:
(lldb) add-dsym --uuid <UUID>

Go and download the dSYM file for the current frame:
(lldb) add-dsym --frame

Make breakpoint setting by file and line much more efficient by only looking for inlined breakpoint locations if we are setting a breakpoint in anything but a source implementation file. Implementing this complex for a many reasons. Turns out that parsing compile units lazily had some issues with respect to how we need to do things with DWARF in .o files. So the fixes in the checkin for this makes these changes:
- Add a new setting called "target.inline-breakpoint-strategy" which can be set to "never", "always", or "headers". "never" will never try and set any inlined breakpoints (fastest). "always" always looks for inlined breakpoint locations (slowest, but most accurate). "headers", which is the default setting, will only look for inlined breakpoint locations if the breakpoint is set in what are consudered to be header files, which is realy defined as "not in an implementation source file". 
- modify the breakpoint setting by file and line to check the current "target.inline-breakpoint-strategy" setting and act accordingly
- Modify compile units to be able to get their language and other info lazily. This allows us to create compile units from the debug map and not have to fill all of the details in, and then lazily discover this information as we go on debuggging. This is needed to avoid parsing all .o files when setting breakpoints in implementation only files (no inlines). Otherwise we would need to parse the .o file, the object file (mach-o in our case) and the symbol file (DWARF in the object file) just to see what the compile unit was.
- modify the "SymbolFileDWARFDebugMap" to subclass lldb_private::Module so that the virtual "GetObjectFile()" and "GetSymbolVendor()" functions can be intercepted when the .o file contenst are later lazilly needed. Prior to this fix, when we first instantiated the "SymbolFileDWARFDebugMap" class, we would also make modules, object files and symbol files for every .o file in the debug map because we needed to fix up the sections in the .o files with information that is in the executable debug map. Now we lazily do this in the DebugMapModule::GetObjectFile()

Cleaned up header includes a bit as well.

Add an lldb command line option to specify a core file: --core/-c.
For consistency, change the "target create" command to also use --core.

Jason Molenda 380241a81f Add a new 'target modules show-unwind' command to show the different
UnwindPlans for a function.  This specifically does not use any
previously-generated UnwindPlans so if any logging is performed
while creating the UnwindPlans, it will be repeated.  This is
useful for when an lldb stack trace is not correct and you want
to gather diagnostic information from the user -- they can do 
log enable -v lldb unwind, image show-unwind of the function, and
you'll get the full logging as the UnwindPlans are recreated.

Greg Clayton f315626fd6 Fixed an issue where if you ask to search the global list of modules for a module with "target modules list", if it found a match in the current target, it would skip looking at the global list. Now if you ask for the global list, we use it and skip the target.

2012-07-07 01:24:12 +00:00
Greg Clayton 234076c429 Fixed the "target modules list" to not crash in Debug builds due to an assertion where the mutex in the "module_list" local variable would assert when the lldb_private::Mutex would destruct. What was happening was the mutex in the module list was being locked by a local locker object and then "module_list" would get destroyed before the locker and the locker still had the mutex locked which would cause the pthread call to destroy the mutex to fail with "Resource busy" and it would cause a mutex leak.

Jim Ingham 5a98841673 Make raw & parsed commands subclasses of CommandObject rather than having the raw version implement an
Execute which was never going to get run and another ExecuteRawCommandString.  Took the knowledge of how
to prepare raw & parsed commands out of CommandInterpreter and put it in CommandObject where it belongs.

Also took all the cases where there were the subcommands of Multiword commands declared in the .h file for
the overall command and moved them into the .cpp file.

Made the CommandObject flags work for raw as well as parsed commands.

Made "expr" use the flags so that it requires you to be paused to run "expr".

Sean Callanan d38b4a998e Added the --all argument to "target modules lookup"
that forces all matches to be looked up.  When --all
is not passed, and the current execution frame can
be used to narrow down the search, "target modules
lookup" will try searching in that specific frame
first.  Only if nothing is turned up there will it
go on to search all modules.

This feature is currently enabled only for types.

Jim Ingham 3ee12ef26e We were accessing the ModuleList in the target without locking it for tasks like
setting breakpoints.  That's dangerous, since while we are setting a breakpoint,
the target might hit the dyld load notification, and start removing modules from
the list.  This change adds a GetMutex accessor to the ModuleList class, and
uses it whenever we are accessing the target's ModuleList (as returned by GetImages().)
