This patch adds support of NativeClient (*-*-nacl) OS support to LLVM.
It's already supported in autoconf/config.sub.

The motivation for this change is to start upstreaming PNaCl work. The
whole set of patches include llvm backends (i686, x86_64, ARM),
llvm-gcc (probably, would not be upstreamed because it's deprecated)
and clang (the work has been just started, the amount of changes is
going to be low and the most of the work is expected to be done close
to the mainline).

Enhance -Wstrl-incorrect-size to not report a FIXIT for destinations that are flexible arrays or have size 1.

STC2L_POST and STC2L_POST should be handled the same as STCL_POST/LDC_POST for the purposes of decoding all operands except the predicate.
Found by randomized testing.

llvm-svn: 138003

Add an option (-p regexp-pattern) to specify the regular expression symbol pattern we're interested in disassembling.

An example:

utils/test/lldb-disasm.py -C "platform select remote-ios" -o "-b -n" -e '~/CoreFoundation' -n 20 -p '-\[NSArray .+\]'

disassembles the first 20 NSArray instance methods found in the CoreFoundation module.

One API change: I added BugReporter as an additional parameter to the BugReporterVisitor::VisitNode() method to allow visitors register other visitors with the report on the fly (while processing a node). This functionality is used by NilReceiverVisitor, which registers TrackNullOrUndefValue when the receiver is null.

Remember to fill in some operands so we can print _something_ coherent even when decoding the CPS instruction soft-fails.

This could be useful by reducing the strain on standard output.

Example:

uncorrected identifier. Fixes a problem pointed out by Eli.

llvm-svn: 137987

Fix base register type and canonicallize to the "ldm" spelling rather than
"ldmia." Add diagnostics for incorrect writeback token and out-of-range
registers.

from the GNU upstream: git://git.savannah.gnu.org/config.git

1. It eliminates a local LLVM patch for auroraux (because, the
mainline config.sub has already got support of auroraux)
2. It adds several new recognized target cpus and operating systems
(in particular, PNaCl)

Reapply r137903, but fix the definition of size_t in the test case to use __SIZE_TYPE__ (and hence be portable).

Also, change the warning to -Wstrl-incorrect-size.

Teach ModuleManager::addModule() to check whether a particular module
has already been loaded before allocating a new Module structure. If
the module has already been loaded (uniquing based on file name), then
just return the existing module rather than trying to load it again.

This allows us to load a DAG of modules. Introduce a simple test case
that forms a diamond-shaped module graph, and illustrates that a
source file importing the bottom of the diamond can see declarations
in all four of the modules that make up the diamond.

LLVM to pull in the older ARM disassembler.  I
also modified our build scripts to support
building LLVM from one SVN revision and Clang
from another.

These are temporary measures; as soon as we
get some solid testing in with the new ARM
disassembler, we plan to switch right back.
