Reimplemented the code that backed the "settings" in lldb. There were many issues with the previous implementation: - no setting auto completion - very manual and error prone way of getting/setting variables - tons of code duplication - useless instance names for processes, threads Now settings can easily be defined like option values. The new settings makes use of the "OptionValue" classes so we can re-use the option value code that we use to set settings in command options. No more instances, just "does the right thing". llvm-svn: 162366

<rdar://problem/12978143> Data formatters now cache themselves. This commit provides a new formatter cache mechanism. Upon resolving a formatter (summary or synthetic), LLDB remembers the resolution for later faster retrieval. Also moved the data formatters subsystem from the core to its own group and folder for easier management, and done some code reorganization. The ObjC runtime v1 now returns a class name if asked for the dynamic type of an object. This is required for formatters caching to work with the v1 runtime. Lastly, this commit disposes of the old hack where ValueObjects had to remember whether they were queried for formatters with their static or dynamic type. Now the ValueObjectDynamicValue class works well enough that we can use its dynamic value setting for the same purpose. llvm-svn: 173728

#include "lldb/Interpreter/CommandCompletions.h"
Decoupled Options from CommandInterpreter. Options used to store a reference to the CommandInterpreter instance in the base Options class. This made it impossible to parse options independent of a CommandInterpreter. This change removes the reference from the base class. Instead, it modifies the options-parsing-related methods to take an ExecutionContext pointer, which the options may inspect if they need to do so.

#include "lldb/Interpreter/CommandInterpreter.h"
Move Args.cpp from Interpreter to Utility Summary: The Args class is used in plenty of places besides the command interpreter (e.g., anything requiring an argc+argv combo, such as when launching a process), so it needs to be in a lower layer. Now that the class has no external dependencies, it can be moved down to the Utility module. This removes the last (direct) dependency from the Host module to Interpreter, so I remove the Interpreter module from Host's dependency list.

Move RegisterValue,Scalar,State from Core to Utility These three classes have no external dependencies, but they are used from various low-level APIs. Moving them down to Utility improves overall code layering (although it still does not break any particular dependency completely). The XCode project will need to be updated after this change.

Rename Error -> Status. This renames the LLDB error class to Status, as discussed on the lldb-dev mailing list. A change of this magnitude cannot easily be done without find and replace, but that has potential to catch unwanted occurrences of common strings such as "Error". Every effort was made to find all the obvious things such as the word "Error" appearing in a string, etc, but it's possible there are still some lingering occurences left around. Hopefully nothing too serious. llvm-svn: 302872

Replaced more boilerplate code with CompletionRequest (NFC) Summary: As suggested in D48796, this patch replaces even more internal calls that were using the old completion API style with a single CompletionRequest. In some cases we also pass an option vector/index, but as we don't always have this information, it currently is not part of the CompletionRequest class. The constructor of the CompletionRequest is now also more sensible. You only pass the user input, cursor position and your list of matches to the request and the rest will be inferred (using the same code we used before to calculate this). You also have to pass these match window parameters to it, even though they are unused right now. The patch shouldn't change any behavior.

Narrow the CompletionRequest API to being append-only. Summary: We currently allow any completion handler to read and manipulate the list of matches we calculated so far. This leads to a few problems: Firstly, a completion handler's logic can now depend on previously calculated results by another handlers. No completion handler should have such an implicit dependency, but the current API makes it likely that this could happen (or already happens). Especially the fact that some completion handler deleted all previously calculated results can mess things up right now. Secondly, all completion handlers have knowledge about our internal data structures with this API. This makes refactoring this internal data structure much harder than it should be. Especially planned changes like the support of descriptions for completions are currently giant patches because we have to refactor every single completion handler. This patch narrows the contract the CompletionRequest has with the different handlers to: 1. A handler can suggest a completion. 2. A handler can ask how many suggestions we already have. Point 2 obviously means we still have a dependency left between the different handlers, but getting rid of this is too large to just append it to this patch. Otherwise this patch just completely hides the internal StringList to the different handlers. The CompletionRequest API now also ensures that the list of completions is unique and we don't suggest the same value multiple times to the user. This property has been so far only been ensured by the `Option` handler, but is now applied globally. This is part of this patch as the OptionHandler is no longer able to implement this functionality itself.
