Kai Nacke 3adf9b8d80 [mips] Add new format for dmtc2/dmfc2 for Octeon CPUs.
Octeon CPUs use dmtc2 rt,imm16 and dmfcp2 rt,imm16 for the crypto coprocessor.
E.g. dmtc2 rt,0x4057 starts calculation of sha-1.

I had to introduce a new deconding namespace to avoid a decoding conflict.

This adds support for the 64-bit DWARF format, but is still limited to

Pavel Labath fb7d5b8384 Fix race in IOHandlerProcessSTDIO
Summary:
IOHandlerProcessSTDIO::Run() was opening the pipe for interrupt requests lazily. This was racing
with another thread executing IOHandlerProcessSTDIO::Cancel() simultaneously. I fix this by
opening the pipe in the object constructor. The pipe will be automatically closed when the object
is destroyed.

Test Plan: Tests pass on linux.

Pavel Labath 05a1f2ac4c [NativeProcessLinux] Support inferiors which change their process group
Summary:
Previously, we wait()ed for events from the inferiors process group. This is resulted in a
failure if the inferior changed its process group in the middle of execution. To avoid this, I
pass -1 to the wait() call. The flag __WNOTHREAD makes sure we don't actually wait for events
from any process, but only the processes(threads) which are our children (or traced by us). Since
this happens on the monitor thread, which is dedicated to monitoring a single inferior, we will
be getting events only from this inferior.

Test Plan: All tests pass on linux. I have added a test to check the new functionality.

David Majnemer 587336d2ad [Reassociate] Canonicalizing 'x [+-] (-Constant * y)' isn't always a win
Canonicalizing 'x [+-] (-Constant * y)' is not a win if we don't *know*
we will open up CSE opportunities.

If the multiply was 'nsw', then negating 'y' requires us to clear the
'nsw' flag.  If this is actually worth pursuing, it is probably more
appropriate to do so in GVN or EarlyCSE.

This fixes PR23675.

Summary:
This patch made two improvements to NaryReassociate and the NVPTX pipeline

1. Run EarlyCSE/GVN after NaryReassociate to get rid of redundant common
expressions.

2. When adding an instruction to SeenExprs, maps both the SCEV before and after
reassociation to that instruction.

Greg Clayton 424a5dbc73 Added a new API to SBFrame:
lldb::addr_t SBFrame::GetCFA();

This gets the CFA (call frame address) of the frame so it allows us to take an address that is on the stack and figure out which thread it comes from.

Also modified the heap.py module to be able to find out which variable in a frame's stack frame contains an address. This way when ptr_refs finds a match on the stack, it get then report which variable contains the pointer.

Greg Clayton 08765fac3f I finally found the strong reference that was keeping all lldb_private::Process instances from ever destroying themselves: ProcessModID.m_mod_id was holding onto the last stop event with ProcessModID::SetStopEventForLastNaturalStopID(EventSP). This is a bad idea because ProcessEventData contains a strong refereence to the process. This is now fixed by calling ProcessModID::SetStopEventForLastNaturalStopID(EventSP()) to clear this event in Process::SetExitStatus() and in Process::Finalize().
This was the original cause of the file descriptor leaks that would cause the test suite to die after running a few hundred processes since no process would ever get destroyed and the communication channel in ProcessGDBRemote and the ProcessIOHandler would never close their pipes. 

This process leak was previously worked around by closing the pipes when the communication channel was disconnected.

This was found by using "ptr_refs" from the heap.py in the lldb.macosx.heap module. It was able to find all strong references to the Process and helped me to figure out who was holding this extra reference.
