This can include objects that have complex state and need to be torn down intelligently (e.g. our SB* objects)
This will fail if the Python interpreter does not hold a valid thread state. So, acquire one, delete the session dictionary, and then let go of it on destruction

We previously passed in a 8192 byte buffer but this wasn't large enough. We now calculate the size we need and then add 128 to it and get the environment. If we pass exactly the number of bytes it says is needs, the sysctl() returns junk. Adding 1 seemed to do the trick, but to err on the side of caution, I added a few bytes more.

for a CXXRecordDecl gets pointed at that record. This can happen when a type is
imported out of and then into the target's AST context without being laid out.
Also added a testcase that covers this scenario.

Make sure we dont treat EINTR as a fatal error. I was getting this when trying to profile the
debugger. I'm not sure why this wasn't surfacing before, it could be that the profiler is using
some signals internally.

Changed the "jthreads" key/value in the stop reply packets to be "jstopinfo". This JSON only contains threads with valid stop reasons and allows us not to have to ask about other threads via qThreadStopInfo when we are stepping. The "jstopinfo" only gets sent if there are more than one thread since the stop reply packet contains all the info needed for a single thread.
Added a Process::WillPublicStop() in case process subclasses want to do any extra gathering for public stops. For ProcessGDBRemote, we end up sending a jThreadsInfo packet to gather all expedited registers, expedited memory and MacOSX queue information. We only do this for public stops to minimize the packets we send when we have multiple private stops. Multiple private stops happen when a source level single step, step into or step out run the process multiple times while implementing the stepping, and none of these private stops make it out to the UI via notifications because they are private stops.

Don't chane the CFI information when a conditional instruction
is emulated (eg.: popeq {r0, pc}) because the CFI for the next
instruction should be the same as the CFI for the current instruction.

Summary:
It seems that reading of register data is the biggest bottleneck in LLGS at the moment. Sending
four registers instead of the full GPR set increases the jThreadsInfo processing time about
6-fold. Until we figure out where is this time going, this commit limits the amount of data we
send to provide a more fluid debugging experience.

Upon connection termination the waitable handle of an IOObject gets reset to an invalid handle.
This caused a problem since we used the object->GetWaitableHandle as a key to the set of
registered events. The fix is to use something more immutable as a key: we make a copy of the
original waitable handle, instead of holding onto the IOObject.

Summary:
This commit adds initial support for the jThreadsInfo packet to lldb-server. The current
implementation does not expedite inferior memory. I have also added a description of the new
packet to our protocol documentation (mostly taken from Greg's earlier commit message).

With static linking lldb-server crashes in platform mode when
tries to listen on localhost:5432 on the android build bot.
This reverts commit 3ea861707dec8423746679ff496e4fd03255d4cf.

SUMMARY:
The patch detects MIPS application specific extensions (ASE) like micromips by reading
ELF header.e_flags and SHT_MIPS_ABIFLAGS section. MIPS triple does not contain ASE
information like micromips, mips16, DSP, MSA etc. These can be read from header.e_flags
or SHT_MIPS_ABIFLAGS section.

frame, don't go any further, in RNBRemote::SendStopReplyPacketForThread.
These are the memory pre-fetches in the T05 packet and are
included in every private stop that lldb does. lldb needs, at most,
the caller stack frame so we're sending more data than needed by
including additional stack memory prefetches in this reply packet.
Once we've stopped for a public stop, we're going to do a jThreadsInfo
which will include the stack memory prefetches for all threads,
including the one which had the stop reason.
llvm-svn: 242380
Summary:
Other changes around the main change include:
1. Add a method Cast to ValueObjectConstResult, ValueObjectConstResultImpl
and ValueObjectConstResultChild.
2. Add an argument |live_address| of type lldb::addr_t to the constructor
of ValueObjectConstResultChild. This is passed on to the backing
ValueObjectConstResultImpl object constructor so that the address of the
child value can be calculated properly.

This allows stepping operations that don't ever do a public stop to get all the info they need without having to send a jThreadsInfo packet since those tend to be large.
This patch will be followed by a patch that will detect when we do a public stop, and when that happens we will send a jThreadsInfo packet at that time to get all expedited registers and memory.
