This fixes a problem from a previous check-in where a return value was omitted.
Previously the remote/stubs-remote.ll and remote/stubs-sm-pic.ll tests were reporting passes, but they should have been failing. Those tests attempt to link against an external symbol and remote symbol resolution is not supported. The old RemoteMemoryManager implementation resulted in local symbols being used for resolution and the child process crashed but the test didn't notice. With this check-in remote symbol resolution fails, and so the test (correctly) fails.

function parameter that has array type. Such a parameter will be treated as
a pointer type instead, resulting in a missing begin function error is a
suggestion to dereference the pointer. This provides a different,
more informative diagnostic as well as point to the parameter declaration.

gdb-format a (as in p/a) would fail as it needed to set a byte size (unsurprisingly enough)
This should be acknowledged by the condition check and not cause a failure

Fixed Module::ResolveSymbolContextForAddress() to be able to also look in the SymbolVendor's SymbolFile's ObjectFile for a more meaningful symbol when a symbol lookup finds a synthetic symbol from the main object file. This will help lookups on MacOSX as the main executable might be stripped, but the dSYM file always has a full symbol table.

This allows the callable_when attribute to be attached to destructors.

Summary:
This way we avoid breaking code which uses unknown preprocessor
directives with long string literals. The specific use case in
http://llvm.org/PR17035 isn't very common, but it seems to be a good idea to
avoid this kind of problem anyway.

Summary:
"svn diff|clang-format-diff.py" will just output the diff.
Now it's possible to use:
svn diff|clang-format-diff.py|patch -p0
as an equivalent to:
svn diff|clang-format-diff.py -i
;)

This is the same as r191695, which was reverted because it depends on a
commit that has issues.

Calling convention attributes can add sugar to methods that we have to
look through. This fixes an assertion failure in the provided test
case.

Added a way to set hardware breakpoints from the "breakpoint set" command with the new "--hardware" option. Hardware breakpoints are not a request, they currently are a requirement. So when breakpoints are specified as hardware breakpoints, they might fail to be set when they are able to be resolved and should be used sparingly. This is currently hooked up for GDB remote debugging.
Linux and FreeBSD should quickly enable this feature if possible, or return an error for any breakpoints that are hardware breakpoint sites in the "virtual Error Process::EnableBreakpointSite (BreakpointSite *bp_site);" function.

In certain macros or incorrect string literals, the token stream can
contain 'unknown' tokens, e.g. a single backslash or a set of empty
ticks. clang-format simply treated them as whitespace and removed them
prior to this patch.
This fixes llvm.org/PR17215

When if converting something like:
true:
... = R0<kill>
false:
... = R0<kill>
then the instructions of the true block must not have a <kill> flag
anymore, as the instruction of the false block follow and do still read
the R0 value.
Specifically this patch determines the set of register live-in in the
false block (possibly after simulating the liveness changes of the
duplicated instructions). Each of these live-in registers mustn't be
killed.

This should fix the buildbots.
Original commit message:
[DAGCombiner] Slice a big load in two loads when the element are next to each
other in memory and the target has paired load and performs post-isel loads
combining.
E.g., this optimization will transform something like this:
a = load i64* addr
b = trunc i64 a to i32
c = lshr i64 a, 32
d = trunc i64 c to i32
into:
b = load i32* addr1
d = load i32* addr2
Where addr1 = addr2 +/- sizeof(i32), if the target supports paired load and
performs post-isel loads combining.
One should overload TargetLowering::hasPairedLoad to provide this information.
The default is false.

There are aliases for --start-group/--end-group options represented
by -( and -) respectively in the command line.
This change adds and improves the test for the alias options to be
tested.
Looks like users use this option widely than explicitly using
--start-group/--end-group.

Just pass a Target* into ObjectFileELF::GetImageInfoAddress so that
it can do the extra dereference necessary on MIPS, instead of passing
a flag back to the caller.
