* Set the state of the process into running/stepping on continue/step operations
* Add mutex to use transactions in Thread State Coordinator
** It is required because the events from two Signal Handler or form a Signal handler and a Resume request shouldn't overlap
* Send Stop Replay Packet only when the state of the process changed
Differential Revision: http://reviews.llvm.org/D7374
llvm-svn: 228387
* Sends a SIGSTOP to the process.
* Fixes busted SIGSTOP handling. Now builds a list of non-stopped
that we wait for the PTRACE group-stop for. When the final must-stop
tid gets its group stop, we propagate the process state change.
Only the signal receiving the notification of the pending SIGSTOP
is marked with the SIGSTOP signal. All the rest, if they weren't
already stopped, are marked as stopped with signal 0.
* Fixes a few broken tests.
* Marks the Linux test I added earlier as expect-pass (no longer XFAIL).
Implements fix for http://llvm.org/bugs/show_bug.cgi?id=20908.

This change:
* properly captures execs in NativeProcessLinux.
* clears out all non-main-thread thread metadata in NativeProcessLinux on exec.
* adds a DidExec() method to the NativeProcessProtocol delegate.
* clears out the auxv data cache when we exec (on Linux).
This is a small part of the llgs for local Linux debugging work going on here:
https://github.com/tfiala/lldb/tree/dev-llgs-local
I'm breaking it into small patches.
llvm-svn: 216670
This change brings in lldb-gdbserver (llgs) specifically for Linux x86_64.
(More architectures coming soon).
Not every debugserver option is covered yet. Currently
the lldb-gdbserver command line can start unattached,
start attached to a pid (process-name attach not supported yet),
or accept lldb attaching and launching a process or connecting
by process id.
The history of this large change can be found here:
https://github.com/tfiala/lldb/tree/dev-tfiala-native-protocol-linux-x86_64
Until mid/late April, I was not sharing the work and continued
to rebase it off of head (developed via id tfiala@google.com). I switched over to
user todd.fiala@gmail.com in the middle, and once I went to github, I did
merges rather than rebasing so I could share with others.
