Eric Christopher 6490bf6072 Allow strict subclasses of register classes, this way we can handle 
ARM instructions with:

foo GPR, rGPR

which happens a lot.

Chandler Carruth 191c4f73b2 Fix some GCC warnings by providing a virtual destructor in the base of a class 
hierarchy with virtual methods and using llvm_unreachable to properly indicate
unreachable states which would otherwise leave variables uninitialized.

Eli Friedman 33087a7fe4 Use std::string instead of StringRef in ClangAttrEmitter.cpp; per report on 
cfe-dev, fixes an error compiling with MSVC.  Using a StringRef here doesn't
look safe in any case.

Johnny Chen 8e8f1c133a Cleaned up the for-disassembly-only entries in the arm instruction table so that 
the memory barrier variants (other than 'SY' full system domain read and write)
are treated as one instruction with option operand.

Bob Wilson 9664984be8 Add a separate ARM instruction format for Saturate instructions. 
(I discovered 2 more copies of the ARM instruction format list, bringing the
total to 4!!  Two of them were already out of sync.  I haven't yet gotten into
the disassembler enough to know the best way to fix this, but something needs
to be done.)  Add support for encoding these instructions.

Bill Wendling 18e853f458 Add back in r109901, which adds a Compare flag to the target instructions. It's 
useful after all.

Rafael Espindola 027d5bcf89 Fix eabi calling convention when a 64 bit value shadows r3. 
Without this what was happening was:

* R3 is not marked as "used"
* ARM backend thinks it has to save it to the stack because of vaarg
* Offset computation correctly ignores it
* Offsets are wrong

Bill Wendling e8bb340203 Revert r109901. The implementation of <rdar://problem/7405933> (r110423) doesn't 
need the Compare flag after all.

Bill Wendling 9b8d586039 Add a "Compare" flag to the target instruction descriptor. This will be used 
later to identify and possibly remove superfluous compare instructions -- those
that are testing for and setting a status flag that should already be set.

Jim Grosbach d343166a0b Many Thumb2 instructions can reference the full ARM register set (i.e., 
have 4 bits per register in the operand encoding), but have undefined
behavior when the operand value is 13 or 15 (SP and PC, respectively).
The trivial coalescer in linear scan sometimes will merge a copy from
SP into a subsequent instruction which uses the copy, and if that
instruction cannot legally reference SP, we get bad code such as:
  mls r0,r9,r0,sp
instead of:
  mov r2, sp
  mls r0, r9, r0, r2

This patch adds a new register class for use by Thumb2 that excludes
the problematic registers (SP and PC) and is used instead of GPR
for those operands which cannot legally reference PC or SP. The
trivial coalescer explicitly requires that the register class
of the destination for the COPY instruction contain the source
register for the COPY to be considered for coalescing. This prevents
errant instructions like that above.
