when selector metadata is generated, which is triggered
by at least on class implementation. This is to match gcc's
behavior. // rdar://8851684.

If interference reaches the last split point, it is effectively live out and
should be marked as 'MustSpill'.
This can make a difference when the terminator uses a register. There is no way
that register can be reused in the outgoing CFG bundle, even if it isn't live
out.

(yes, this is different from R_ARM_CALL)
- Adds a new method getARMBranchTargetOpValue() which handles the
necessary distinction between the conditional and unconditional br/bl
needed for ARM/ELF
At least for ARM mode, the needed fixup for conditional versus unconditional
br/bl is identical, but the ARM docs and existing ARM tools expect this
reloc type...
Added a few FIXME's for future naming fixups in ARMInstrInfo.td

A live range cannot be split everywhere in a basic block. A split must go before
the first terminator, and if the variable is live into a landing pad, the split
must happen before the call that can throw.
llvm-svn: 124894
We should not be attempting a region split if it won't lead to at least one
directly allocatable interval. That could cause infinite splitting loops.

Internal use means for compiling the LLDB debug engine and plug-ins, but it
should never make it into the public API.
Since we don't currently have a configuration script that detects avaiable
functionality in the LLDB build system, we are hard coding #define values
in the host specific "Config.h" files.
#define values in these Config.h header files should set the value to zero or
one:
#define LLDB_CONFIG_TERMIOS_SUPPORTED 1
#define LLDB_CONFIG_OTHER 0
Then any code in the LLDB engine should check the availability using:
#if LLDB_CONFIG_TERMIOS_SUPPORTED
....
#endif
Eventually the contents of the host specific Config.h files will be auto
generated, but for now they will be hard coded. Any LLDB_CONFIG_XXXX items
that are added should be added to all Config.h files and set to either zero
or one.

One (stepout.patch) to fix a problem in ThreadPlanStepOut.cpp. There is an erroneous semi colon at end of an if statement that make the condition useless (if body is empty).
And the second patch is to remove to useless typedef on enum, and so avoid a lot of warnings with clang++.

id-expression, e.g.,
CurrentClass<T>::member
Previously, if CurrentClass<T> was dependent and not complete, we
would treat it as a dependent-scoped declaration reference expression,
even if CurrentClass<T> referred to the current instantiation.
Fixes PR8966 and improves type checking of templates.
llvm-svn: 124867
it's okay for the following template parameters to not have default
arguments (since those template parameters can still be
deduced). Also, downgrade the error about default template arguments
in function templates to an extension warning, since this is a
harmless C++0x extension.

precisely track pressure on a selection DAG, but we can at least keep
it balanced. This design accounts for various interesting aspects of
selection DAGS: register and subregister copies, glued nodes, dead
nodes, unused registers, etc.
Added SUnit::NumRegDefsLeft and ScheduleDAGSDNodes::RegDefIter.
Note: I disabled PrescheduleNodesWithMultipleUses when register
pressure is enabled, based on no evidence other than I don't think it
makes sense to have both enabled.

(lldb) process connect <remote-url>
Currently when you specify a file with the file command it helps us to find
a process plug-in that is suitable for debugging. If you specify a file you
can rely upon this to find the correct debugger plug-in:
% lldb a.out
Current executable set to 'a.out' (x86_64).
(lldb) process connect connect://localhost:2345
...
If you don't specify a file, you will need to specify the plug-in name that
you wish to use:
% lldb
(lldb) process connect --plugin process.gdb-remote connect://localhost:2345
Other connection URL examples:
(lldb) process connect connect://localhost:2345
(lldb) process connect tcp://127.0.0.1
(lldb) process connect file:///dev/ttyS1
We are currently treating the "connect://host:port" as a way to do raw socket
connections. If there is a URL for this already, please let me know and we
will adopt it.
So now you can connect to a remote debug server with the ProcessGDBRemote
plug-in. After connection, it will ask for the pid info using the "qC" packet
and if it responds with a valid process ID, it will be equivalent to attaching.
If it response with an error or invalid process ID, the LLDB process will be
in a new state: eStateConnected. This allows us to then download a program or
specify the program to run (using the 'A' packet), or specify a process to
attach to (using the "vAttach" packets), or query info about the processes
that might be available.
