52f792329be5db8e38961350589e97e8f2823acd 12-Jul-2013 Greg Clayton <gclayton@apple.com> Huge change to clean up types.

A long time ago we start with clang types that were created by the symbol files and there were many functions in lldb_private::ClangASTContext that helped. Later we create ClangASTType which contains a clang::ASTContext and an opauque QualType, but we didn't switch over to fully using it. There were a lot of places where we would pass around a raw clang_type_t and also pass along a clang::ASTContext separately. This left room for error.

This checkin change all type code over to use ClangASTType everywhere and I cleaned up the interfaces quite a bit. Any code that was in ClangASTContext that was type related, was moved over into ClangASTType. All code that used these types was switched over to use all of the new goodness.

This patch fixes the issue that we were using the C stack as a measure of depth of ValueObject hierarchies, in the sense that we were assuming that recursive ValueObject operations would never be deeper than the stack allows.
This assumption is easy to prove wrong, however.
For instance, after ~10k runs through this loop:
struct node
{
int value;
node* child;
node (int x)
{
value = x;
child = nullptr;
}
};

int main ()
{
node root(1);
node* ptr = &root;
int j = 2;
while (1)
{
ptr->child = new node(j++);
ptr = ptr->child;
}
return 0;
}

the deepmost child object will be deeper than the stack on most architectures, and we would be unable to display it

This checkin fixes the issue by introducing a notion of root of ValueObject hierarchies.
In a couple cases, we have to use an iterative algorithm instead of going to the root because we want to allow deeper customizations (e.g. formats, dynamic values).
While the patch passes our test suite without regressions, it is a good idea to keep eyes open for any unexpected behavior (recursion can be subtle..)
Also, I am hesitant to introduce a test case since failing at this will not just be marked as an "F", but most definitely crash LLDB.

Many "byte size" members and variables were using a mixture of uint32_t and size_t. Switching over to using uint64_t everywhere.

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.

Fixed type lookups to "do the right thing". Prior to this fix, looking up a type using "foo::bar" would result in a type list that contains all types that had "bar" as a basename unless the symbol file was able to match fully qualified names (which our DWARF parser does not).

This fix will allow type matches to be made based on the basename and then have the types that don't match filtered out. Types by name can be fully qualified, or partially qualified with the new "bool exact_match" parameter to the Module::FindTypes() method.

This fixes some issue that we discovered with dynamic type resolution as well as improves the overall type lookups in LLDB.

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.

931acecd4e3af534028936431dc0f75a9fd6eb02 23-Feb-2012 Sean Callanan <scallanan@apple.com> Added support for looking up the complete type for
Objective-C classes. This allows LLDB to find
ivars declared in class extensions in modules other
than where the debugger is currently stopped (we
already supported this when the debugger was
stopped in the same module as the definition).

This involved the following main changes:

- The ObjCLanguageRuntime now knows how to hunt
for the authoritative version of an Objective-C
type. It looks for the symbol indicating a
definition, and then gets the type from the
module containing that symbol.

- ValueObjects now report their type with a
potential override, and the override is set if
the type of the ValueObject is an Objective-C
class or pointer type that is defined somewhere
other than the original reported type. This
means that "frame variable" will always use the
complete type if one is available.

- The ClangASTSource now looks for the complete
type when looking for ivars. This means that
"expr" will always use the complete type if one
is available.

- I added a testcase that verifies that both
"frame variable" and "expr" work.

b4d7fc0c466d446876e5f2d701f0e574dd0be8e7 17-Feb-2012 Greg Clayton <gclayton@apple.com> This checking is part one of trying to add some threading safety to our
internals. The first part of this is to use a new class:

lldb_private::ExecutionContextRef

This class holds onto weak pointers to the target, process, thread and frame
and it also contains the thread ID and frame Stack ID in case the thread and
frame objects go away and come back as new objects that represent the same
logical thread/frame.

ExecutionContextRef objcets have accessors to access shared pointers for
the target, process, thread and frame which might return NULL if the backing
object is no longer available. This allows for references to persistent program
state without needing to hold a shared pointer to each object and potentially
keeping that object around for longer than it needs to be.

You can also "Lock" and ExecutionContextRef (which contains weak pointers)
object into an ExecutionContext (which contains strong, or shared pointers)
with code like

ExecutionContext exe_ctx (my_obj->GetExectionContextRef().Lock());

9c236733d43e6250c8a5671a438f4a2afeb9c0b2 26-Oct-2011 Greg Clayton <gclayton@apple.com> Cleaned up many error codes. For any who is filling in error strings into
lldb_private::Error objects the rules are:
- short strings that don't start with a capitol letter unless the name is a
class or anything else that is always capitolized
- no trailing newline character
- should be one line if possible

Implemented a first pass at adding "--gdb-format" support to anything that
accepts format with optional size/count.

915448044bac6fdac22a33cc46697dcb771a8df2 06-Sep-2011 Enrico Granata <granata.enrico@gmail.com> Redesign of the interaction between Python and frozen objects:
- introduced two new classes ValueObjectConstResultChild and ValueObjectConstResultImpl: the first one is a ValueObjectChild obtained from
a ValueObjectConstResult, the second is a common implementation backend for VOCR and VOCRCh of method calls meant to read through pointers stored
in frozen objects ; now such reads transparently move from host to target as required
- as a consequence of the above, removed code that made target-memory copies of expression results in several places throughout LLDB, and also
removed code that enabled to recognize an expression result VO as such
- introduced a new GetPointeeData() method in ValueObject that lets you read a given amount of objects of type T from a VO
representing a T* or T[], and doing dereferences transparently
in private layer it returns a DataExtractor ; in public layer it returns an instance of a newly created lldb::SBData
- as GetPointeeData() does the right thing for both frozen and non-frozen ValueObject's, reimplemented ReadPointedString() to use it
en lieu of doing the raw read itself
- introduced a new GetData() method in ValueObject that lets you get a copy of the data that backs the ValueObject (for pointers,
this returns the address without any previous dereferencing steps ; for arrays it actually reads the whole chunk of memory)
in public layer this returns an SBData, just like GetPointeeData()
- introduced a new CreateValueFromData() method in SBValue that lets you create a new SBValue from a chunk of data wrapped in an SBData
the limitation to remember for this kind of SBValue is that they have no address: extracting the address-of for these objects (with any
of GetAddress(), GetLoadAddress() and AddressOf()) will return invalid values
- added several tests to check that "p"-ing objects (STL classes, char* and char[]) will do the right thing
Solved a bug where global pointers to global variables were not dereferenced correctly for display
New target setting "max-string-summary-length" gives the maximum number of characters to show in a string when summarizing it, instead of the hardcoded 128
Solved a bug where the summary for char[] and char* would not be shown if the ValueObject's were dumped via the "p" command
Removed m_pointers_point_to_load_addrs from ValueObject. Introduced a new m_address_type_of_children, which each ValueObject can set to tell the address type
of any pointers and/or references it creates. In the current codebase, this is load address most of the time (the only notable exception being file
addresses that generate file address children UNLESS we have a live process)
Updated help text for summary-string
Fixed an issue in STL formatters where std::stlcontainer::iterator would match the container's synthetic children providers
Edited the syntax and help for some commands to have proper argument types

Also change the SourceInitFile to look for .lldb-<APPNAME> and source that
preferentially if it exists.
Also made the breakpoint site report its address as well as its breakpoint number
when it gets hit and can't find any the associated locations (usually because the
breakpoint got disabled or deleted programmatically between the time it was hit
and reported.)
Changed ThreadPlanCallFunction to initialize the ivar m_func in the initializers of the
constructor, rather than waiting to initialize till later on in the function.
Fixed a bug where if you make an SBError and the ask it Success, it returns false.
Fixed ValueObject::ResolveValue so that it resolves a temporary value, rather than
overwriting the one in the value object.

Fixed a bug where Objective-C variables coming out of the expression parser could crash the Python synthetic providers:
- expression parser output has a "frozen data" component, which is a byte-exact copy of the value (in host memory),
if trying to read into memory based on the host address, LLDB would crash. we are now passing the correct (target)
pointer to the Python code
Objective-C "id" variables are now formatted according to their dynamic type, if the -d option to frame variable is used:
- Code based on the Objective-C 2.0 runtime is used to obtain this information without running code on the target

801417e453f8531ac176cd952200587bf15d9ccf 07-Jul-2011 Greg Clayton <gclayton@apple.com> Added "target variable" command that allows introspection of global
variables prior to running your binary. Zero filled sections now get
section data correctly filled with zeroes when Target::ReadMemory
reads from the object file section data.

Added new option groups and option values for file lists. I still need
to hook up all of the options to "target variable" to allow more complete
introspection by file and shlib.

Added the ability for ValueObjectVariable objects to be created with
only the target as the execution context. This allows them to be read
from the object files through Target::ReadMemory(...).

Added a "virtual Module * GetModule()" function to the ValueObject
class. By default it will look to the parent variable object and
return its module. The module is needed when we have global variables
that have file addresses (virtual addresses that are specific to
module object files) and in turn allows global variables to be displayed
prior to running.

Removed all of the unused proxy object support that bit rotted in
lldb_private::Value.

Replaced a lot of places that used "FileSpec::Compare (lhs, rhs) == 0" code
with the more efficient "FileSpec::Equal (lhs, rhs)".

Improved logging in GDB remote plug-in.

"struct ", "class ", and "union " from the start of any type names that are

e41494a9092e15192012a5e0a8a1ffd66c70b8bb 16-Apr-2011 Jim Ingham <jingham@apple.com> Add support for "dynamic values" for C++ classes. This currently only works for "frame var" and for the
expressions that are simple enough to get passed to the "frame var" underpinnings. The parser code will
have to be changed to also query for the dynamic types & offsets as it is looking up variables.

The behavior of "frame var" is controlled in two ways. You can pass "-d {true/false} to the frame var
command to get the dynamic or static value of the variables you are printing.

There's also a general setting:

target.prefer-dynamic-value (boolean) = 'true'

which is consulted if you call "frame var" without supplying a value for the -d option.

That means all the ValueObject evaluate me type functions that used to require a Frame object now do not.

b01000fd063629facd45044f137446fb748ee179 17-Jan-2011 Greg Clayton <gclayton@apple.com> A few of the issue I have been trying to track down and fix have been due to
the way LLDB lazily gets complete definitions for types within the debug info.
When we run across a class/struct/union definition in the DWARF, we will only
parse the full definition if we need to. This works fine for top level types
that are assigned directly to variables and arguments, but when we have a
variable with a class, lets say "A" for this example, that has a member:
"B *m_b". Initially we don't need to hunt down a definition for this class
unless we are ever asked to do something with it ("expr m_b->getDecl()" for
example). With my previous approach to lazy type completion, we would be able
to take a "A *a" and get a complete type for it, but we wouldn't be able to
then do an "a->m_b->getDecl()" unless we always expanded all types within a
class prior to handing out the type. Expanding everything is very costly and
it would be great if there were a better way.

A few months ago I worked with the llvm/clang folks to have the
ExternalASTSource class be able to complete classes if there weren't completed
yet:

class ExternalASTSource {
....

virtual void
CompleteType (clang::TagDecl *Tag);

virtual void
CompleteType (clang::ObjCInterfaceDecl *Class);
};

This was great, because we can now have the class that is producing the AST
(SymbolFileDWARF and SymbolFileDWARFDebugMap) sign up as external AST sources
and the object that creates the forward declaration types can now also
complete them anywhere within the clang type system.

This patch makes a few major changes:
- lldb_private::Module classes now own the AST context. Previously the TypeList
objects did.
- The DWARF parsers now sign up as an external AST sources so they can complete
types.
- All of the pure clang type system wrapper code we have in LLDB (ClangASTContext,
ClangASTType, and more) can now be iterating through children of any type,
and if a class/union/struct type (clang::RecordType or ObjC interface)
is found that is incomplete, we can ask the AST to get the definition.
- The SymbolFileDWARFDebugMap class now will create and use a single AST that
all child SymbolFileDWARF classes will share (much like what happens when
we have a complete linked DWARF for an executable).

We will need to modify some of the ClangUserExpression code to take more
advantage of this completion ability in the near future. Meanwhile we should
be better off now that we can be accessing any children of variables through
pointers and always be able to resolve the clang type if needed.

427f290ff96f3ab9f2cf3a1af7001d2c560424c7 14-Dec-2010 Greg Clayton <gclayton@apple.com> 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.

6916e358c9725b75ed91f31236c147f26c9af10e 13-Nov-2010 Greg Clayton <gclayton@apple.com> Modified the lldb_private::Type clang type resolving code to handle three
cases when getting the clang type:
- need only a forward declaration
- need a clang type that can be used for layout (members and args/return types)
- need a full clang type

This allows us to partially parse the clang types and be as lazy as possible.
The first case is when we just need to declare a type and we will complete it
later. The forward declaration happens only for class/union/structs and enums.
The layout type allows us to resolve the full clang type _except_ if we have
any modifiers on a pointer or reference (both R and L value). In this case
when we are adding members or function args or return types, we only need to
know how the type will be laid out and we can defer completing the pointee
type until we later need it. The last type means we need a full definition for
the clang type.

Did some renaming of some enumerations to get rid of the old "DC" prefix (which
stands for DebugCore which is no longer around).

Modified the clang namespace support to be almost ready to be fed to the
expression parser. I made a new ClangNamespaceDecl class that can carry around
the AST and the namespace decl so we can copy it into the expression AST. I
modified the symbol vendor and symbol file plug-ins to use this new class.

Specifically, we fixed handling of the objc_class
built-in type, which allowed us to pass
named Objective-C objects to functions,
call variable list -t on objects safely, etc.

bf8e42b9da0e1c6349a727d644ad37610b00d556 15-Oct-2010 Greg Clayton <gclayton@apple.com> Fixed an expression parsing issue where if you were stopped somewhere without
debug information and you evaluated an expression, a crash would occur as a
result of an unchecked pointer.

Added the ability to get the expression path for a ValueObject. For a rectangle
point child "x" the expression path would be something like: "rect.top_left.x".
This will allow GUI and command lines to get ahold of the expression path for
a value object without having to explicitly know about the hierarchy. This
means the ValueObject base class now has a "ValueObject *m_parent;" member.
All ValueObject subclasses now correctly track their lineage and are able
to provide value expression paths as well.

Added a new "--flat" option to the "frame variable" to allow for flat variable
output. An example of the current and new outputs:

(lldb) frame variable
argc = 1
argv = 0x00007fff5fbffe80
pt = {
x = 2
y = 3
}
rect = {
bottom_left = {
x = 1
y = 2
}
top_right = {
x = 3
y = 4
}
}
(lldb) frame variable --flat
argc = 1
argv = 0x00007fff5fbffe80
pt.x = 2
pt.y = 3
rect.bottom_left.x = 1
rect.bottom_left.y = 2
rect.top_right.x = 3
rect.top_right.y = 4


As you can see when there is a lot of hierarchy it can help flatten things out.
Also if you want to use a member in an expression, you can copy the text from
the "--flat" output and not have to piece it together manually. This can help
when you want to use parts of the STL in expressions:

(lldb) frame variable --flat
argc = 1
argv = 0x00007fff5fbffea8
hello_world._M_dataplus._M_p = 0x0000000000000000
(lldb) expr hello_world._M_dataplus._M_p[0] == '\0'

462d4147f3bb9141bf62d904f58a623db00669df 29-Sep-2010 Greg Clayton <gclayton@apple.com> Fixed the forward declaration issue that was present in the DWARF parser after
adding methods to C++ and objective C classes. In order to make methods, we
need the function prototype which means we need the arguments. Parsing these
could cause a circular reference that caused an assertion.

Added a new typedef for the clang opaque types which are just void pointers:
lldb::clang_type_t. This appears in lldb-types.h.

This was fixed by enabling struct, union, class, and enum types to only get
a forward declaration when we make the clang opaque qual type for these
types. When they need to actually be resolved, lldb_private::Type will call
a new function in the SymbolFile protocol to resolve a clang type when it is
not fully defined (clang::TagDecl::getDefinition() returns NULL). This allows
us to be a lot more lazy when parsing clang types and keeps down the amount
of data that gets parsed into the ASTContext for each module.

Getting the clang type from a "lldb_private::Type" object now takes a boolean
that indicates if a forward declaration is ok:

clang_type_t lldb_private::Type::GetClangType (bool forward_decl_is_ok);

So function prototypes that define parameters that are "const T&" can now just
parse the forward declaration for type 'T' and we avoid circular references in
the type system.

defines that are in "llvm/Support/MachO.h". This should allow ObjectFileMachO
and ObjectContainerUniversalMachO to be able to be cross compiled in Linux.

Also did some cleanup on the ASTType by renaming it to ClangASTType and
renaming the header file. Moved a lot of "AST * + opaque clang type *"
functionality from lldb_private::Type over into ClangASTType.
