We want the representative register class to contain the largest
super-registers available. This makes the function less sensitive to the
register class numbering.

In file included from ../lib/Target/NVPTX/VectorElementize.cpp:53:

  default: assert(0 && "Unknown condition code");

1 warning generated.

The prevailing pattern in LLVM is to not use a default label, and instead to
use llvm_unreachable to denote that the switch in fact covers all return paths
from the function.

add a new Region::block_iterator which actually iterates over the basic
blocks of the region.

The old iterator, now call 'block_node_iterator' iterates over
RegionNodes which contain a single basic block. This works well with the
GraphTraits-based iterator design, however most users actually want an
iterator over the BasicBlocks inside these RegionNodes. Now the
'block_iterator' is a wrapper which exposes exactly this interface.
Internally it uses the block_node_iterator to walk all nodes which are
single basic blocks, but transparently unwraps the basic block to make
user code simpler.

While this patch is a bit of a wash, most of the updates are to internal
users, not external users of the RegionInfo. I have an accompanying
patch to Polly that is a strict simplification of every user of this
interface, and I'm working on a pass that also wants the same simplified
interface.

This patch alone should have no functional impact.

Added an interactive mode to the "crashlog" command so that we can look at multiple crash logs at once and do some data mining. Added an interactive command prompt that allows you to do:

% PYTHONPATH=./build/Debug/LLDB.framework/Resources/Python ; ./build/Debug//LLDB.framework/Resources/Python/lldb/macosx/crashlog.py -i ~/Downloads/crashes2/*.crash ) 

then you get an interactive prompt where you can search for data within all crash logs. For example you can do:

% list

which will list all crash logs

And you can search for all images given an image basename, or full path:

% image LLDB
% image /Applications/Xcode.app/Contents/SharedFrameworks/LLDB.framework/Versions/A/LLDB
% image LLDB.framework

Which would all produce an output listing like:

This patch adds a new NVPTX back-end to LLVM which supports code generation for NVIDIA PTX 3.0. This back-end will (eventually) replace the current PTX back-end, while maintaining compatibility with it.

The new target machines are:

nvptx (old ptx32) => 32-bit PTX
nvptx64 (old ptx64) => 64-bit PTX

The sources are based on the internal NVIDIA NVPTX back-end, and
contain more functionality than the current PTX back-end currently
provides.

Fix a think in Mutex::Locker::Locker(pthread_mutex_t *)  Really should lock the mutex handed in, not the m_mutex_ptr that you've set to NULL...
Rework the Host.cpp::ThreadNameAccessor to use ThreadSafeSTLMap - we've got it so we might as well use it.  Also works around a problem with the
Mutex::Locker class raising fallacious asserts in debug mode when used with pthread_mutex_t's that weren't backed by Mutex objects.

getTypeSourceInfo() without checking for NULL.
FieldDecls may have NULL TypeSourceInfo, and in

off PartialDiagnostic. PartialDiagnostic is rather heavyweight for
something that is in the critical path and is rarely used. So, switch
over to an abstract-class-based callback mechanism that delays most of
the work until a diagnostic is actually produced. Good for ~11k code
size reduction in the compiler and 1% speedup in -fsyntax-only on the
code in <rdar://problem/11004361>.
