Jim Ingham a2cf2637da For the language check in GetObjectDescription, if we can't find a language runtime for the value we're looking at, BUT it IS at least a pointer, try the ObjCRuntime language. That's currently the only language runtime that has an object description method anyway...

Johnny Chen d161a85700 Broadcaster::AddListener(): Bail out early if the passed in Listener pointer is
NULL, instead of registering a NULL listener and to crash later.

Jason Molenda f830e481c2 RegisterContextLLDB.cpp (InitializeNonZerothFrame): If we get a
0 mid-stack, stop backtracing.

SectionLoadList.cpp (ResolveLoadAddress): Don't assert on an
out-of-range address, just return an invalid Address object.
The unwinder may be passing in invalid addresses on the final
stack frame and the assert is a problem.

Greg Clayton bdea7cee67 Remove an assertion that is causing crashes. We do need to find a way to reproduce when this assertion asserts, but we should crash our debug session because of it. For now we log to stderr in hope of tracking it down.

Caroline Tice 3d6086f628 Add code to make sure InputReaders finish and are cleaned up when
a Debugger object is destroyed or re-set. (Thus making sure that, for
example, the Python interpreter finishes and exits cleanly rather than
being left in an undefined state.)

Greg Clayton fff42e6241 Line tables were trying to be too clever and only use 24 bits for a line
table offset where the offset is within a section. Increased the section
offset for line table entries to be 32 bits (from 24 bits), giving each 
section a 4G offset, and increased the section index to 32 bits (from 8 bits).

Greg Clayton 6ad07dd9e9 Improved our argument parsing abilities to be able to handle stuff more like
a shell would interpret it. A few examples that we now handle correctly

INPUT: "Hello "world
OUTPUT: "Hello World"

INPUT: "Hello "' World'
OUTPUT: "Hello World"

INPUT: Hello" World"
OUTPUT: "Hello World"

This broke the setting of dictionary values for the "settings set" command
for things like:

(lldb) settings set target.process.env-vars ["MY_ENV_VAR"]=YES

since we would drop the quotes. I fixed the user settings controller to use
a regular expression so it can accept any of the following inputs for
dictionary setting:

settings set target.process.env-vars ["MY_ENV_VAR"]=YES
settings set target.process.env-vars [MY_ENV_VAR]=YES
settings set target.process.env-vars MY_ENV_VAR=YES

We might want to eventually drop the first two syntaxes, but I won't make
that decision right now.

This allows more natural setting of the envirorment variables:

settings set target.process.env-vars MY_ENV_VAR=YES ABC=DEF CWD=/tmp

Greg Clayton f028a1fb84 Added access to set the current stack frame within a thread so any command
line commands can use the current thread/frame.

Fixed an issue with expressions that get sandboxed in an objective C method
where unichar wasn't being passed down.

Added a "static size_t Scalar::GetMaxByteSize();" function in case we need
to know the max supported by size of something within a Scalar object.

Sean Callanan e4ec90e990 Implemented a feature where the expression parser
can avoid running the code in the target if the
expression's result is known and the expression
has no side effects.

Right now this feature is quite conservative in
its guess about side effects, and it only computes
integer results, but the machinery to make it more
sophisticated is there.

Greg Clayton bdf4c6ac4f Fixed an error where the thread index was being returned as zero in "uint32_t SBBreakpoint::GetThreadIndex() const" even when it isn't specified. It should be UINT32_MAX to indicate there is no thread index set for the breakpoint (the breakpoint isn't thread specific). Also fixed the ThreadSpec.cpp to use UINT32_MAX instead of -1. Fixed the logging Printf statement in "uint32_t SBBreakpoint::GetThreadIndex() const" to not print the address of the "index" function from <string.h>!

Greg Clayton 54979cddda Fixed the "expression" command object to use the StackFrame::GetValueForExpressionPath()
function and also hooked up better error reporting for when things fail.

Fixed issues with trying to display children of pointers when none are
supposed to be shown (no children for function pointers, and more like this).
This was causing child value objects to be made that were correctly firing
an assertion.

Jason Molenda 3f8688b614 Move the demangle-failed indication out a bit so other failing cases

Jason Molenda b690fbbaec Fix a crash on some platforms where a dSYM for a system library lists a DW_AT_mips_linkage_name for
a non-mangled function - we pass the non mangled string down through abi::__cxa_demangle and it
crashes.  Usually passing non mangled strings to abi::__cxa_demangle works out fine but not
always, apparently.

Caroline Tice 472362e6ed Fix small bugs:
- Make sure cmd_obj & cmd_obj_sp contain a valid objects before attempting to 
dereference, in CommandObjectCommandsAlias::Execute and 
CommandInterpreter::HandleCommand.

multi-word command inputs.

Greg Clayton 69b582fa94 Changed:
SBValue SBFrame::LookupVar(const char *name);
To
	SBValue SBFrame::FindVariable (const char *name);

Changed:
	SBValue LookupVarInScope (const char *name, const char *scope);
to
	SBValue FindValue (const char *name, ValueType value_type);

The latter makes it possible to not only find variables (params, locals, globals, and statics), but we can also now get register sets, registers and persistent variables using the frame as the context.

Greg Clayton 8b2fe6dcbd Modified LLDB expressions to not have to JIT and run code just to see variable
values or persistent expression variables. Now if an expression consists of
a value that is a child of a variable, or of a persistent variable only, we
will create a value object for it and make a ValueObjectConstResult from it to
freeze the value (for program variables only, not persistent variables) and
avoid running JITed code. For everything else we still parse up and JIT code
and run it in the inferior. 

There was also a lot of clean up in the expression code. I made the 
ClangExpressionVariables be stored in collections of shared pointers instead
of in collections of objects. This will help stop a lot of copy constructors on
these large objects and also cleans up the code considerably. The persistent
clang expression variables were moved over to the Target to ensure they persist
across process executions.

Added the ability for lldb_private::Target objects to evaluate expressions.
We want to evaluate expressions at the target level in case we aren't running
yet, or we have just completed running. We still want to be able to access the
persistent expression variables between runs, and also evaluate constant 
expressions. 

Added extra logging to the dynamic loader plug-in for MacOSX. ModuleList objects
can now dump their contents with the UUID, arch and full paths being logged with
appropriate prefix values.

Thread hardened the Communication class a bit by making the connection auto_ptr
member into a shared pointer member and then making a local copy of the shared
pointer in each method that uses it to make sure another thread can't nuke the
connection object while it is being used by another thread.

Added a new file to the lldb/test/load_unload test that causes the test a.out file
to link to the libd.dylib file all the time. This will allow us to test using
the DYLD_LIBRARY_PATH environment variable after moving libd.dylib somewhere else.

Sean Callanan 9d48e80426 Bugfixes for the new "self" pointer handling. Specifically,
the code to pass the _cmd pointer has been improved, and _cmd
is now set to the value of _cmd for the current context, as
opposed to being simply NULL.

llvm-svn: 121739
2010-12-14 00:42:36 +00:00
Sean Callanan 1782783095 Added support for generating expressions that have
access to the members of the Objective-C self object.

The approach we take is to generate the method as a
@category on top of the self object, and to pass the
"self" pointer to it.  (_cmd is currently NULL.)

Most changes are in ClangExpressionDeclMap, but the
change that adds support to the ABIs to pass _cmd
touches a fair amount of code.

2010-12-13 20:05:03 +00:00
Greg Clayton c30abdfa7d Fixed a crasher where when a ProcessGDBRemote class was being destroyed, it would eventually destroy the dynamic loader (when the lldb_private::Process::m_dynamic_loader_ap destroys itself in the object member destructor chain). The dynamic loader was calling a pure virtual method in Process which was causing a crash. The quick fix is to reset the auto pointer in the ProcessGDBRemote destructor when ProcessGDBRemote is still a valid object with all its pure virtual functions intact.

Sean Callanan 481144790c Updated to latest Clang revision. This involved
very minor changes, changing how we get the target
type from a TypedefType, adding a parameter to
EnumDecl::Create(), and other minor tweaks.

2010-12-13 01:26:27 +00:00
Greg Clayton bfae66ae1d Fixed a multi-threaded race condition that could happen when communication classes are shutting down. We currently don't protect communication connection classes against multi-threaded access. The connection is stored in the lldb_private::Communication.m_connection_ap auto_ptr member. We either need to add protections when accessing this class or not let anything racy occur. With this fix, we are doing the latter.

Greg Clayton 7d07a45fff Fixed an issue where the macosx dynamic loader, on the first shared library loaded notification, wasn't properly removing shared libraries from the target that didn't get loaded. This usually happens when a different shared library is loaded in place of another due to DYLD_LIBRARY_PATH or DYLD_FRAMEWORK_PATH environment variables. We now properly remove any images that didn't make it into the executable.
