Jakob Stoklund Olesen dd9a2ecef7 Treat clones the same as their origin. 
When DCE clones a live range because it separates into connected components,
make sure that the clones enter the same register allocator stage as the
register they were cloned from.

For instance, clones may be split even when they where created during spilling.
Other registers created during spilling are not candidates for splitting or even
(re-)spilling.

Jim Ingham 406ef962d9 The example had gotten stale, so I made it work again, and for fun printed out the frame registers as well.

Devang Patel 4d7612744f Fix in r128471 is very broad. Some of the unconditional branches need line number information for better user experience. 
Restrict the fix. This fixes break.exp failures from gdb testsuite.

Francois Pichet c68476480e Update CMake link dependency. 
llvm-svn: 128503

Evan Cheng 18381b4257 Add intrinsics @llvm.arm.neon.vmulls and @llvm.arm.neon.vmullu.* back. Frontends 
was lowering them to sext / uxt + mul instructions. Unfortunately the
optimization passes may hoist the extensions out of the loop and separate them.
When that happens, the long multiplication instructions can be broken into
several scalar instructions, causing significant performance issue.

Note the vmla and vmls intrinsics are not added back. Frontend will codegen them
as intrinsics vmull* + add / sub. Also note the isel optimizations for catching
mul + sext / zext are not changed either.

First part of rdar://8832507, rdar://9203134

Jim Ingham 7572fa75cf Can't just call "rand" to get a random port, 'cause then you'll get the same sequence in two lldb's. This makes running lldb on lldb not work very well.

Oscar Fuentes 978e5284fa Fixed the build of Clang's unit tests on MinGW. Also removed some 
unnecesary conditionals and introduced a new convenience function.

The problem was that the list of libraries for Clang's unit tests was
<clang libraries> <system libraries> <llvm libraries>. As the llvm
libraries references symbols defined on the system libraries, those
were reported as undefined.
