Modified demo to use 3.0 resume instruction vs calling _Unwine_Resume.
...
Also conducted some reformatting. As the LLVM coding standard doc does not
seem to touch on how to align function arguments, and format code longer than
80 cols in general, the confusion persists. There is the golden rule, but as
this code has gone through several styles to deal with this, the golden rule
seems to be ignored. The latest reformatting effort tries to match the other
source files as much as possible.
Tested on OS X 10.7.1 with, and without the OLD_EXC_SYSTEM defined. Have NOT
tested on LINUX.

Sometimes register class constraints are trivial, like GR32->GR32_NOSP,

register instead of emitting a copy in these cases.
Normally, these copies are handled by the coalescer. This saves some
coalescer work.

Do not unnecessarily use AT_specification DIE because it does not add any value.

Few weeks ago, llvm completely inverted the debug info graph. Earlier each debug info node used to keep track of its compile unit, now compile unit keeps track of important nodes. One impact of this change is that the global variable's do not have any context, which should be checked before deciding to use AT_specification DIE.

Lower ARM adds/subs to add/sub after adding optional CPSR operand.
...
This is still a hack until we can teach tblgen to generate the
optional CPSR operand rather than an implicit CPSR def. But the
strangeness is now limited to the selection DAG. ADD/SUB MI's no
longer have implicit CPSR defs, nor do we allow flag setting variants
of these opcodes in machine code. There are several corner cases to
consider, and getting one wrong would previously lead to nasty
miscompilation. It's not the first time I've debugged one, so this
time I added enough verification to ensure it won't happen again.

lib/Linker: add support of deps which does not end with ".so".
...
It happens (for example) when you want to have a dependency on the .so
with the specific version, like liblzma.so.1.0.0 or
libcrypto.so.0.9.8.

Update this test to the new EH model.
...
Though I think it may be obsolete with the loop extract changes. And I couldn't
get the old version of LLVM to compile so that I could reduce this testcase.

Relax this condition.

Some passes require breaking critical edges before they're called. Don't
segfault because of that.

Omit extracting a loop if one of the exits is a landing pad.
...
The landing pad must accompany the invoke when it's extracted. However, if it
does, then the loop isn't properly extracted. I.e., the resulting extraction has
a loop in it. The extracted function is then extracted, etc. resulting in an
infinite loop.

Remove the hack to check UNAME_RELEASE when identifying the Darwin version.
...
This was only needed to locate llvm-gcc's installation directory when clang
falls back to run llvm-gcc for i386 kexts. As of clang svn r140187, we're
now just searching paths with several different Darwin versions on either
side of the current version, so this is no longer needed.
