The legalized code uses two vector INT_TO_FP operations and is faster
than scalarizing.

Add a utility similar to disasm.py, but which provides a shell-like environment for invoking llvm-mc.

The relevant instruction table entries were changed sometime ago to no longer take
<Rt2> as an operand.  Modify ARMDisassemblerCore.cpp to accomodate the change and
add a test case.

platform status -- gets status information for the selected platform
platform create <platform-name> -- creates a new instance of a remote platform
platform list -- list all available platforms
platform select -- select a platform instance as the current platform (not working yet)

When using "platform create" it will create a remote platform and make it the
selected platform. For instances for iPhone OS debugging on Mac OS X one can 
do:

(lldb) platform create remote-ios --sdk-version=4.0
Remote platform: iOS platform
SDK version: 4.0
SDK path: "/Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.0"
Not connected to a remote device.
(lldb) file ~/Documents/a.out
Current executable set to '~/Documents/a.out' (armv6).
(lldb) image list
[  0] /Volumes/work/gclayton/Documents/devb/attach/a.out
[  1] /Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.0/Symbols/usr/lib/dyld
[  2] /Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.0/Symbols/usr/lib/libSystem.B.dylib


Note that this is all happening prior to running _or_ connecting to a remote
platform. Once connected to a remote platform the OS version might change which
means we will need to update our dependecies. Also once we run, we will need
to match up the actualy binaries with the actualy UUID's to files in the
SDK, or download and cache them locally.

This is just the start of the remote platforms, but this modification is the
first iteration in getting the platforms really doing something.

This rename serves two purposes:

- It reflects the actual functionality of this analysis.
- We will have more than one reachability analysis.

Tweak CrashRecoveryContextCleanup to provide an easy method for clients to select between 'delete' and 'destructor' cleanups, and allow the destructor of CrashRecoveryContextCleanupRegister to be pseudo re-entrant.

llvm-svn: 127929

Tweak CrashRecoveryContext::GetCurrent() to return quickly if 'gCrsahRecoveryEnabled' is false.  This avoids us needing to go to thread local storage for
the performance sensitive case where we are compiling code.

If an AllocaInst referred by DbgDeclareInst is used by a LoadInst then the LoadInst should also get a corresponding llvm.dbg.value intrinsic.

Add libclang hook 'clang_toggleCrashRecovery()', which provides a mechanism for a client to enable/disable CrashRecovery within libclang function calls.

Run all functional logic of clang_annotateTokens() within a CrashRecoveryContext.  Fixes <rdar://problem/9121698>.

Add support to the ARM asm parser for the register-shifted-register forms of basic instructions like ADD.  More work left to be done to support other instances of shifter ops in the ISA.

Proof-of-concept code that code-gens a module to an in-memory MachO object.
This will be hooked up to a run-time dynamic linker library (see: llvm-rtdyld
for similarly conceptual work for that part) which will take the compiled
object and link it together with the rest of the system, providing back to the
JIT a table of available symbols which will be used to respond to the
getPointerTo*() queries.

llvm-svn: 127916

add support for the OpenCL __private, __local, __constant and
__global address spaces, as well as the __read_only, _read_write and
__write_only image access specifiers.  Patch originally by ARM;
language-specific address space support by myself.

Remove '-Xclang' and '-mllvm' entries from Clang man page.  The later is only available in debug builds and the former is not supposed to be used by end-users.

The llvm.dbg.value intrinsic refers to SSA values, not virtual registers, so we
should be able to extend the range of a value by tracking that value through
register copies. This greatly improves the debug value tracking for function
arguments that for some reason are copied to a second virtual register at the
end of the entry block.

We only extend the debug value range where its register is killed. All original
llvm.dbg.value locations are still respected.

Copies from physical registers are ignored. That should not be a problem since
the entry block already adds DBG_VALUE instructions for the virtual registers
holding the function arguments.

 - We don't really support the majority of the horrible -traditional-cpp
   behavior, but it is unlikely that we ever will either. This allows us to
   start trying to use clang as a /usr/bin/cpp replacement and see what pieces
   of -traditional-cpp mode people actually care about.
