Sean Callanan 596ab8ee08 Added support for extracting method information from
Objective-C symbols.  The methods aren't used yet if
there is a competing definition in the DWARF; I will
resolve that next.

Greg Clayton 1ba6cfd1e6 After moving lldb::pid_t to 64 bits, keep a deprecated version around for
previous binaries that link against this for a few builds to make sure we
can continue to run against previous binaries.

Greg Clayton e04741d03a <rdar://problem/10394517>
Fixed templates with NonTypeTemplateParmDecl objects. For example:

template <unsigned N>
....

This fixes SmallVector and all of the other classes that have template params
that are non types.

Greg Clayton 61e7a58c0c Process IDs (lldb::pid_t) and thread IDs (lldb::tid_t) are now 64 bit. This
will allow us to represent a process/thread ID using a pointer for the OS
plug-ins where they might want to represent the process or thread ID using
the address of the process or thread structure.

Sean Callanan e0a64f7302 Modified clients of ClangASTImporter to be more robust
in the face of failures to import types, since blithely
passing on NULL types can sometimes lead to trouble.

Also eliminated a use of getAs and replaced it with
dyn_cast, which is more robust.

Sean Callanan a5230ce303 Picked up a new revision of Clang to pull in Objective-C
enhancements.  With these enhancements, the return values
of Objective-C methods with unknown return types can be
implicitly cast to id for the purpose of making method
calls.

So what would have required this:

(int)[(id)[ClassWithNoDebugInfo methodReturningObject] methodReturningInt]

can now be written as:

(int)[[ClassWithNoDebugInfo methodReturningObject] methodReturningInt]

Sean Callanan 947ccc7396 Made symbol lookup in the expression parser more
robust:

- Now a client can specify what kind of symbols
  are needed; notably, this allows looking up
  Objective-C class symbols specifically.

- In the class of symbols being looked up, if
  one is non-NULL and others are NULL, LLDB now
  prefers the non-NULL one.

Johnny Chen 60e2c6aa43 rdar://problem/10501020
ClangASTSource::~ClangASTSource() was calling

    ClangASTContext *scratch_clang_ast_context = m_target->GetScratchClangASTContext();

which had the side effect of deleting this very ClangASTSource instance.  Not good.
Change it to

    // We are in the process of destruction, don't create clang ast context on demand
    // by passing false to Target::GetScratchClangASTContext(create_on_demand).
    ClangASTContext *scratch_clang_ast_context = m_target->GetScratchClangASTContext(false);

The Target::GetScratchClangASTContext(bool create_on_demand=true) has a new signature.

Sean Callanan 09ab4b777c Added support to the Objective-C language runtime
to find Objective-C class types by looking in the
symbol tables for the individual object files.

I did this as follows:

- I added code to SymbolFileSymtab that vends
  Clang types for symbols matching the pattern
  "_OBJC_CLASS_$_NSMyClassName," making them
  appear as Objective-C classes.  This only occurs
  in modules that do not have debug information,
  since otherwise SymbolFileDWARF would be in
  charge of looking up types.

- I made a new SymbolVendor subclass for the
  Apple Objective-C runtime that is in charge of
  making global lookups of Objective-C types.  It
  currently just sends out type lookup requests to
  the appropriate SymbolFiles, but in the future we
  will probably extend it to query the runtime more
  completely.

I also modified a testcase whose behavior is changed
by the fact that we now actually return an Objective-C
type for __NSCFString.

Fix wrong test logic in test_modules_search_paths().  Add additional exercising of 'target modules search-paths list/query".
There is a reproducible crash if 'target modules search-paths clear' is exercised during test teardown.

Johnny Chen 49cb85db64 SBProcess.PutSTDIN() needs to be properly typemapped when swigging,
so that we can do Python scripting like this:

        target = self.dbg.CreateTarget(self.exe)

        self.dbg.SetAsync(True)
        process = target.LaunchSimple(None, None, os.getcwd())

        process.PutSTDIN("Line 1 Entered.\n")
        process.PutSTDIN("Line 2 Entered.\n")
        process.PutSTDIN("Line 3 Entered.\n")

Add TestProcessIO.py to exercise the process IO API: PutSTDIN()/GetSTDOUT()/GetSTDERR().

Greg Clayton cc23eb6fbf Now the linux platform lets it be known that it can't launch processes for

2011-11-28 01:47:46 +00:00
Greg Clayton c982b3d6e6 CommandObjectProcess was recently changed to automatically use the platform
to launch a process for debugging. Since this isn't supported on all platforms,
we need to do what we used to do if this isn't supported. I added:

    bool
    Platform::CanDebugProcess ();
    
This will get checked before trying to launch a process for debugging and then
fall back to launching the process through the current host debugger. This
should solve the issue for linux and keep the platform code clean.

Centralized logging code for logging errors, warnings and logs when reporting
things for modules or symbol files. Both lldb_private::Module and 
lldb_private::SymbolFile now have the following member functions:

    void                    
    LogMessage (Log *log, const char *format, ...);

    void
    ReportWarning (const char *format, ...);

    void
    ReportError (const char *format, ...);

These will all output the module name and object (if any) such as:

    "error: lldb.so ...."
    "warning: my_archive.a(foo.o) ...."
    
This will keep the output consistent and stop a lot of logging calls from 
having to try and output all of the information that uniquely identifies
a module or symbol file. Many places in the code were grabbing the path to the
object file manually and if the module represented a .o file in an archive, we
would see log messages like:

    error: foo.a - some error happened

Greg Clayton e372b98d18 Many GDB users always want to display disassembly when they stop by using
something like "display/4i $pc" (or something like this). With LLDB we already
were showing 3 lines of source before and 3 lines of source after the current
source line when showing a stop context. We now improve this by allowing the
user to control the number of lines with the new "stop-line-count-before" and
"stop-line-count-after" settings. Also, there is a new setting for how many
disassembly lines to show: "stop-disassembly-count". This will control how many
source lines are shown when there is no source or when we have no source line
info. 

settings set stop-line-count-before 3
settings set stop-line-count-after 3
settings set stop-disassembly-count 4
settings set stop-disassembly-display no-source

The default values are set as shown above and allow 3 lines of source before 
and after (what we used to do) the current stop location, and will display 4 
lines of disassembly if the source is not available or if we have no debug
info. If both "stop-source-context-before" and "stop-source-context-after" are
set to zero, this will disable showing any source when stopped. The 
"stop-disassembly-display" setting is an enumeration that allows you to control
when to display disassembly. It has 3 possible values:

"never" - never show disassembly no matter what
"no-source" - only show disassembly when there is no source line info or the source files are missing
"always" - always show disassembly.
