This is an NFC commit to refactor the "load dependent files" parameter
from a boolean to an enum value. We want to be able to specify a
default, in which case we decide whether or not to load the dependent
files based on whether the target is an executable or not (i.e. a
dylib).
This is a dependency for D51934.

Summary:
This patch adds a framework for adding descriptions to the command completions we provide.
It also adds descriptions for completed top-level commands so that we can test this code.
Completions are in general supposed to be displayed alongside the completion itself. The descriptions
can be used to provide additional information about the completion to the user. Examples for descriptions
are function signatures when completing function calls in the expression command or the binary name
when providing completion for a symbol.
There is still some boilerplate code from the old completion API left in LLDB (mostly because the respective
APIs are reused for non-completion related purposes, so the CompletionRequest doesn't make sense to be
used), so that's why I still had to change some function signatures. Also, as the old API only passes around a
list of matches, and the descriptions are for these functions just another list, I had to add some code that
essentially just ensures that both lists are always the same side (e.g. all the manual calls to
`descriptions->AddString(X)` below a `matches->AddString(Y)` call).
The initial command descriptions that come with this patch are just reusing the existing
short help that is already added in LLDB.
An example completion with descriptions looks like this:
```
(lldb) pl
Available completions:
platform -- Commands to manage and create platforms.
plugin -- Commands for managing LLDB plugins.

Building LLDB with xcodebuild sets the compatibility version of liblldb
in LLDB.framework. Building the framework with cmake does not set the
compatibility version, and so it defaults to 0.0.0. This is a discrepency in the
difference between the xcode build and the cmake build.
I tested this change by building without this patch. From the build tree I ran
`otool -L Library/Frameworks/LLDB.framework/Versions/A/LLDB` and got this:
```

Summary:
Previously, I thought that install-liblldb would fail because CMake had
a bug related to installing frameworks. In actuality, I misunderstood the
semantics of `add_custom_target`: the DEPENDS option refers to specific files,
not targets. Therefore `install-liblldb` should rely on the actual liblldb
getting generated rather than the target.
This means that the previous patch I committed (to stop relying on CMake's
framework support) is no longer needed and has been reverted. Using CMake's
framework support greatly simplifies the implementation.
`install-lldb-framework` (and the stripped variant) is as simple as
depending on `install-liblldb` because CMake knows that liblldb was built as a
framework and will install the whole framework for you. The stripped variant
will depend on the stripped variants of individual tools only to ensure they
actually are stripped as well.

lldb-framework truly does depend on lldb-suite (liblldb + related tools).
In this change I want to invert their dependency. This will mean that lldb and
finish_swig will depend on lldb-framework in a framework build, and lldb-suite
otherwise. Instead of adding conditional logic everywhere to handle this, I
introduce LLDB_SUITE_TARGET to handle it.

This change allows to make AddressClass strongly typed enum and not to have issues with old versions of SWIG that don't support enum classes.
llvm-svn: 335710
Summary:
During the previous attempt to generalize the UUID class, it was
suggested that we represent invalid UUIDs as length zero (previously, we
used an all-zero UUID for that). This meant that some valid build-ids
could not be represented (it's possible however unlikely that a checksum of
some file would be zero) and complicated adding support for variable
length build-ids (should a 16-byte empty UUID compare equal to a 20-byte
empty UUID?).
This patch resolves these issues by introducing a canonical
representation for an invalid UUID. The slight complication here is that
some clients (MachO) actually use the all-zero notation to mean "no UUID
has been set". To keep this use case working (while making it very
explicit about which construction semantices are wanted), replaced the
UUID constructors and the SetBytes functions with named factory methods.
- "fromData" creates a UUID from the given data, and it treats all bytes
equally.
- "fromOptionalData" first checks the data contents - if all bytes are
zero, it treats this as an invalid/empty UUID.

3) Create a target lldb-suite, which depends on every tool and library that makes liblldb fully functional. One result of having this target is it makes tracking dependencies much clearer.

Summary:
There was some confusion in the code about how to represent process
environment. Most of the code (ab)used the Args class for this purpose,
but some of it used a more basic StringList class instead. In either
case, the fact that the underlying abstraction did not provide primitive
operations for the typical environment operations meant that even a
simple operation like checking for an environment variable value was
several lines of code.
This patch adds a separate Environment class, which is essentialy a
llvm::StringMap<std::string> in disguise. To standard StringMap
functionality, it adds a couple of new functions, which are specific to
the environment use case:
- (most important) envp conversion for passing into execve() and likes.
Instead of trying to maintain a constantly up-to-date envp view, it
provides a function which creates a envp view on demand, with the
expectation that this will be called as the very last thing before
handing the value to the system function.
- insert(StringRef KeyEqValue) - splits KeyEqValue into (key, value)
pair and inserts it into the environment map.
- compose(value_type KeyValue) - takes a map entry and converts in back
into "KEY=VALUE" representation.
With this interface most of the environment-manipulating code becomes
one-liners. The only tricky part was maintaining compatibility in
SBLaunchInfo, which expects that the environment entries are accessible
by index and that the returned const char* is backed by the launch info
object (random access into maps is hard and the map stores the entry in
a deconstructed form, so we cannot just return a .c_str() value). To
solve this, I have the SBLaunchInfo convert the environment into the
"envp" form, and use it to answer the environment queries. Extra code is
added to make sure the envp version is always in sync.
(This also improves the layering situation as Args was in the Interpreter module
whereas Environment is in Utility.)

This changes moves the dependency management from the individual targets

The final targets will pick up these libraries as they will be a part of
the link interface of the module.

This change makes the names independent holders of breakpoint options
that you can then apply to breakpoints when you add the name to the
breakpoint. It adds the "breakpoint name configure" command to set
up or reconfigure breakpoint names. There is also full support for
then in the SB API, including a new SBBreakpointName class.
The connection between the name and the breakpoints
sharing the name remains live, so if you reconfigure the name, all the
breakpoint options all change as well. This allows a quick way
to share complex breakpoint behavior among a bunch of breakpoints, and
a convenient way to iterate on the set.
You can also create a name from a breakpoint, allowing a quick way
to copy options from one breakpoint to another.
I also added the ability to make hidden and delete/disable protected
names. When applied to a breakpoint, you will only be able to list,
delete or disable that breakpoint if you refer to it explicitly by ID.
This feature will allow GUI's that need to use breakpoints for their
own purposes to keep their breakpoints from getting accidentally
disabled or deleted.

Summary:
The available platform list was previously only accessible via the
`platform list` command, this patch makes it possible to access that
list via the SBDebugger API. The active platform list has likewise
been exposed via the SBDebugger API.

You can get a breakpoint to auto-continue by adding "continue"
as a command, but that has the disadvantage that if you hit two
breakpoints simultaneously, the continue will force the process
to continue, and maybe even forstalling the commands on the other.
The auto-continue flag means the breakpoints can negotiate about
whether to stop.
Writing tests, I wanted to supply some commands when I made the
breakpoints, so I also added that ability.

When an option was set at on a location, I was just copying the whole option set
to the location, and letting it shadow the breakpoint options. That was wrong since
it meant changes to unrelated options on the breakpoint would no longer take on this
location. I added a mask of set options and use that for option propagation.
I also added a "location" property to breakpoints, and added SBBreakpointLocation.{G,S}etCommandLineCommands
since I wanted to use them to write some more test cases.

This patch does the following:
* Gets the header copy step to re-run whenever header change
* Gets the header fix-up step to re-run whenever headers are copied

On iOS frameworks don't have versions or resources, they are flatter bundles. This updates the LLDB framework build to accommodate the flatter bundles.
llvm-svn: 309025
This adds an explicit step for processing the headers and restructures how the framework bundles are constructed. This should make the frameworks more reliably constructed.

This commit removes a very old deprecated API that was causing compile failures for LLDB on Darwin. Since the comment says we only needed to keep the old API around for a few Xcode builds, and the comment was written 6 years ago... I think this can safely go away.

SBBreakpointLocation exposed the ignore count, but didn't expose

some methods in the ABI need a Process to do their work.
Instead of passing it in as a one-off argument to those
methods, this patch puts it in the base class and the methods
can retrieve if it needed.
Note that ABI's are sometimes built without a Process
(e.g. SBTarget::GetStackRedZoneSize) so it's entirely
possible that the process weak pointer will not be
able to reconsistitue into a strong pointer.

Summary:
These interfaces have no dependencies, so it makes sense for them to be
in the lowest level modules, to make sure that other parts of the
codebase can use them without introducing loops.
The only exception here is the Connection::CreateDefaultConnection
method, which I've moved to Host, as it instantiates concrete
implementations, and that's where the implementations live.

Summary:
The new UndefinedBehaviorSanitizer plugin was breaking file path length
limits, because it's (fairly long name) appears multiple times in the
path. Cmake ends up putting the object file at path
tools/lldb/source/Plugins/InstrumentationRuntime/UndefinedBehaviorSanitizer/CMakeFiles/lldbPluginInstrumentationRuntimeUndefinedBehaviorSanitizer.dir/UndefinedBehaviorSanitizerRuntime.cpp.obj
which is 191 characters long and very dangerously close to the 260
character path limit on windows systems (also, just the include line for
that file was breaking the 80 character line limit).
This renames the sanitizer plugins to use shorter names (asan, ubsan,
tsan). I think this will still be quite understandable to everyone as
those are the names everyone uses to refer to them anyway.

The Timer destructor would grab a global mutex in order to update
execution time. Add a class to define a category once, statically; the
class adds itself to an atomic singly linked list, and thus subsequent
updates only need to use an atomic rather than grab a lock and perform a
hashtable lookup.

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.

If we can't find the "is dyld locked" symbol, assume it is safe
to load the image unless we only have 1 image loaded - in which case
we are in _dyld_start and it is definitely NOT safe.
Also add a little better errors to that function, and better logging
in SBProcess.cpp.

Summary:
This patch introduces new SB APIs for tracing support
inside LLDB. The idea is to gather trace data from
LLDB and provide it through this APIs to external
tools integrating with LLDB. These tools will be
responsible for interpreting and presenting the
trace data to their users.
The patch implements the following new SB APIs ->
-> StartTrace - starts tracing with given parameters
-> StopTrace - stops tracing.
-> GetTraceData - read the trace data .
-> GetMetaData - read the meta data assosciated with the trace.
-> GetTraceConfig - read the trace configuration
Tracing is associated with a user_id that is returned
by the StartTrace API and this id needs to be used
for accessing the trace data and also Stopping
the trace. The user_id itself may map to tracing
the complete process or just an individual thread.
The APIs require an additional thread parameter
when the user of these APIs wishes to perform
thread specific manipulations on the tracing instances.
The patch also includes the corresponding
python wrappers for the C++ based APIs.
