This fixes some regressions in the piglit local memory store tests
introduced by recent commits which made the scheduler aware of the trans
slot.
It's not possible to test this using lit, because there is no way to
determine from the assembly dumps whether or not an instruction is in
the trans slot.
Even if this were possible, the test would be highly sensitive to
changes in the scheduler and might generate confusing false negatives.

This allows the PC to be directly changed to a different line.
It's similar to the example python script in examples/python/jump.py, except implemented as a builtin.
Also this version will track the current function correctly even if the target line resolves to multiple addresses. (e.g. debugging a templated function)

communication, connection, host, module, mmap, os. Add those. Also
sort the entries so they come in alphabetical order, to make it a
little easier to scan down the list for a specific channel.

SVN r189964 provided a sample Python script to inspect unordered(multi){set|map} with synthetic children, contribued by Jared Grubb
This checkin converts that sample script to a C++ provider built into LLDB
A test case is also provided

As Andy pointed out to me a long time ago, there are no structural hazards in
the later pipeline stages of the A2, and so modeling them is useless. Also,
modeling the top pre-dispatch stages is deceiving because, when multiple
hardware threads are active, those resources are shared among the threads. The
bypass definitions were mostly wrong, and so those have been removed. The
resulting itinerary is much simpler, and more accurate.

It'd be another issue that the terminal and stdout(including redirects) with utf8. This test XPASSed on Win32, at least on Lit.
FYI, we don't use a triplet like "-win64" anywhere.

Now that LLVM's helper script GetSVN.cmake actually works consistently,
there's no reason not to use it. This does mean that the clangBasic target
is potentially always dirty, because CMake-generated projects do not
necessarily recalculate dependencies after running each target.
This should end the issues of the AST format changing and breaking old
module files; CMake-Clang should now detect that the version changed just
like Autoconf-Clang has.
llvm-svn: 190557
This allows the logic to work with Git, and also uses the variable names
to match what Clang is actually looking for.
This changes the interface of GetSVN.cmake. Clang change to follow.

The PowerPC A2 core greatly benefits from aggressive concatenation unrolling;
use the new getUnrollingPreferences to enable this by default when targeting
the PPC A2 core.
llvm-svn: 190549
Allow targets to customize the default behavior of the generic loop unrolling
transformation. This will be used by the PowerPC backend when targeting the A2
core (which is in-order with a deep pipeline), and using more aggressive
defaults is important.

Definition of DIRef used to require the full definition of DIType because
of usage of DIType::isType in DIRef::resolve. We now use DIDescriptor::isType
instead to remove the requirement and move definition of DIRef before DIType.
With this, we can move the definition of DIType::getContext to the header
file.

Summary:
This test only works on systems capable of outputting UTF-8 encoded
text on the standard output (tested on linux and OS X, should XFAIL on windows,
if I haven't messed up the XFAIL line).

- This is a work-in-progress and all details are subject to change, but I am
trying to build up support for allowing lit to be used as a driver for
performance tests (or other tests which might want to record information
beyond simple PASS/FAIL).

RegionStore tries to protect against accidentally initializing the same
region twice, but it doesn't take subregions into account very well. If
the outer region being initialized is a struct with an empty base class,
the offset of the first field in the struct will be 0. When we initialize
the base class, we may invalidate the contents of the struct by providing
a default value of Unknown (or some new symbol). We then go to initialize
the member with a zeroing constructor, only to find that the region at
that offset in the struct already has a value. The best we can do here is
to invalidate that value and continue; neither the old default value nor
the new 0 is correct for the entire struct after the member constructor call.
The correct solution for this is to track region extents in the store.

Normally RAV visits parameter variable declarations of a function by traversing the TypeLoc of
the parameter declarations. However, for implicit functions, their parameters don't have any
TypeLoc, because they are implicit.
So for implicit functions, we visit their parameter variable declarations by traversing them through
the function declaration, and visit them accordingly.
