Jim Ingham f77bb46dc0 Add an example command to toggle between disassembly-only and source mode.
Sometimes you are debugging in source, but you really only want to see
the disassembly.  That's easy to do but you have to set a few variables.
This command toggles between your old values, and a disassembly only mode.

Pavel Labath 68e3886e57 Recompute ArchSpec core after MergeFrom
Summary:
MergeFrom was updating the architecture if the target triple did not
have it set. However, it was leaving the core field as invalid. This
resulted in assertion failures in core file tests as a missing core
meant we were unable to compute the address byte size properly.

Add a unit test for the new behaviour.

Pavel Labath 7b46633c4b Make TestStaticVariables XFAIL more specific
The test fails because an older clang did not emit the required debug
info (I am not sure when this got added, but clang-3.7 certainly did not
work yet). The actual platform has nothing to do with this.

David Gross 36d783ebfe Teach RenderScriptRuntime about changed context representation.
Summary:
The runtime discovers contexts through RenderScriptRuntime::Capture*()
methods.  These methods see the low-level context representation.
However, the runtime calls APIs that require the high-level context
representation.  Therefore, it needs to call yet another API to find
the high-level representation associated with a given low-level
representation.

Pavel Labath 107e694271 Revert yesterdays IPv6 patches
The break the linux bots (and probably any other machine which would
run the test suite in a massively parallel way). The problem is that it
can happen that we only successfully create an IPv6 listening socket
(because the relevant IPv4 port is used by another process) and then the
connecting side attempts to connect to the IPv4 port and fails.

It's not very obvious how to fix this problem, so I am reverting this
until we come up with a solution.

Chris Bieneman d01a2fa38d Update DebugServer to support IPv6 over TCP
Summary: This patch adds IPv6 support to debugserver. It follows a similar pattern to the changes proposed for LLDB/Host except that the listen implementation is only with kqueue(2) because debugserver is only supported on Darwin.

Chris Bieneman 31e7c5e89f Update LLDB Host to support IPv6 over TCP
Summary:
This patch adds IPv6 support to LLDB/Host's TCP socket implementation. Supporting IPv6 involved a few significant changes to the implementation of the socket layers, and I have performed some significant code cleanup along the way.

This patch changes the Socket constructors for all types of sockets to not create sockets until first use. This is required for IPv6 support because the socket type will vary based on the address you are connecting to. This also has the benefit of removing code that could have errors from the Socket subclass constructors (which seems like a win to me).

The patch also slightly changes the API and behaviors of the Listen/Accept pattern. Previously both Listen and Accept calls took an address specified as a string. Now only listen does. This change was made because the Listen call can result in opening more than one socket. In order to support listening for both IPv4 and IPv6 connections we need to open one AF_INET socket and one AF_INET6 socket. During the listen call we construct a map of file descriptors to addrin structures which represent the allowable incoming connection address. This map removes the need for taking an address into the Accept call.

This does have a change in functionality. Previously you could Listen for connections based on one address, and Accept connections from a different address. This is no longer supported. I could not find anywhere in LLDB where we actually used the APIs in that way. The new API does still support AnyAddr for allowing incoming connections from any address.

The Listen implementation is implemented using kqueue on FreeBSD and Darwin, WSAPoll on Windows and poll(2) everywhere else.

Kamil Rytarowski 36e23ecad0 Introduce FPR and Debug Registers/NetBSD/amd64 support
Summary:
This code offers Debug Registers (80386) model in LLDB/amd64.

This is initial support and has one issue that will be addressed later,
Debug Register trap (TRAP_DBREG) is registered as (TRAP_TRACE)
for unknown reason.  On the other hand this works good enough to
move on and leave this bug to be squashed later.

Improve the NativeProcessNetBSD::ReinitializeThreads() function,
stop setting inside it SetStoppedByExec(). This fixes incorrect
stop reason on attaching (SetStoppedBySignal(SIGSTOP)).

This commits also has no functional style improvements from
clang-format.

This code also ships with FXSAVE support on NetBSD.

Davide Italiano cf8a8294e5 [Interpreter] Make a static func a lambda and remove always_inline.
The attribute was fairly dubious as: a) we shouldn't tell the compiler
when to inline functions, b) GCC complains that the function may be
not always inlinable.

Chris Bieneman b90bee044b [CMake] Support generating Config.h
Summary:
This patch removes the hand maintained config files in favor of auto-generating the config file. We will still need to maintain the defines for the Xcode builds on Mac, but all CMake builds use the generated header instead.

This will enable finer grained platform support tests and enable supporting LLDB on more platforms with less manual maintenance.

I have only tested this patch on Darwin, and any help testing it out on other platforms would be greatly appreciated. I've probably messed something up somewhere.
