1e496fad4f Added AsmWriterInst.cpp to the CMakeList so that 
it builds OK on Visual Studio.

1248c51819 Per PR 6219, factored AsmWriterInst and AsmWriterOperand 
out of the AsmWriterEmitter.  This patch does the physical
code movement, but leaves the implementation unchanged. I'll
make any changes necessary to generalize the code in a
separate patch.

7acf9be6c4 move target-independent opcodes out of TargetInstrInfo 
into TargetOpcodes.h.  #include the new TargetOpcodes.h
into MachineInstr.  Add new inline accessors (like isPHI())
to MachineInstr, and start using them throughout the 
codebase.

83ebc265b3 Reintroduce the InlineHint function attribute. 
This time it's for real! I am going to hook this up in the frontends as well.

The inliner has some experimental heuristics for dealing with the inline hint.
When given a -respect-inlinehint option, functions marked with the inline
keyword are given a threshold just above the default for -O3.

We need some experiments to determine if that is the right thing to do.

1942b96584 Modified the register matcher function in AsmMatcher to 
be static.  Also made it possible for clients to get it
and no other functions from ...GenAsmMatcher.inc by
defining REGISTERS_ONLY before including GenAsmMatcher.inc.
This sets the stage for target-specific lexers that can
identify registers and return AsmToken::Register as
appropriate.

c82f536a5c The change in r90189 adds a link in a directory outside the iPhone platform 
directory when building the llvmCore_Embedded project.  Fix this by putting
the iPhone platform directory into DEST_DIR instead of DEST_ROOT.  I also
noticed what appears to be an unintentional use of DEVELOPER_BIN instead of
DEVELOPER_DIR, so I fixed that and changed to use DEVELOPER_DIR in some places
that were hardcoded to "Developer".  Finally, the other changes here allowed
some refactoring and simplification, which I have done.

882cb240a6 Split the TargetAsmParser "ParseInstruction" interface in half: 
the new ParseInstruction method just parses and returns a list of
target operands.  A new MatchInstruction interface is used to
turn the operand list into an MCInst.

This requires new/deleting all the operands, but it also gives 
targets the ability to use polymorphic operands if they want to.

cdbc36f961 Reimplement getToken and SplitString as "StringRef helper functions" 
- getToken is modeled after StringRef::split but it can split on multiple
  separator chars and skips leading seperators.
- SplitString is a StringRef::split variant for more than 2 elements with the
  same behaviour as getToken.

4ef1119d94 Partially address a README by having functionattrs consider calls to 
memcpy, memset and other intrinsics that only access their arguments
to be readnone if the intrinsic's arguments all point to local memory.
This improves the testcase in the README to readonly, but it could in
theory be made readnone, however this would involve more sophisticated
analysis that looks through the memcpy.

18fa59f381 Table-driven disassembler for the X86 architecture (16-, 32-, and 64-bit 
incarnations), integrated into the MC framework.  

The disassembler is table-driven, using a custom TableGen backend to 
generate hierarchical tables optimized for fast decode.  The disassembler 
consumes MemoryObjects and produces arrays of MCInsts, adhering to the 
abstract base class MCDisassembler (llvm/MC/MCDisassembler.h).

The disassembler is documented in detail in

- lib/Target/X86/Disassembler/X86Disassembler.cpp (disassembler runtime)
- utils/TableGen/DisassemblerEmitter.cpp (table emitter)

You can test the disassembler by running llvm-mc -disassemble for i386
or x86_64 targets.  Please let me know if you encounter any problems
with it.

da651bf31a FileCheck, PR5239: Try to find the intended match on failures, but looking for a 
good nearby fuzzy match. Frequently the input is nearly correct, and just
showing the user the a nearby sensible match is enough to diagnose the problem.
 - The "fuzzyness" is pretty simple and arbitrary, but worked on my three test
   cases. If you encounter problems, or places you think FileCheck should have
   guessed but didn't, please add test cases to PR5239.

For example, previously FileCheck would report this:
--
t.cpp:21:55: error: expected string not found in input
// CHECK: define void @_Z2f25f2_s1([[i64_i64_ty]] %a0)
                                                      ^
<stdin>:19:30: note: scanning from here
define void @_Z2f15f1_s1(%1) nounwind {
                             ^
<stdin>:19:30: note: with variable "i64_i64_ty" equal to "%0"
--

and now it also reports this:
--
<stdin>:27:1: note: possible intended match here
define void @_Z2f25f2_s1(%0) nounwind {
^
--

which makes it clear that the CHECK just has an extra ' %a0' in it, without
having to check the input.

5d46596707 Fix pr5470. Tablegen handles template arguments by temporarily setting their 
values, resolving references to them, and then removing the definitions.
If a template argument is set to an undefined value, we need to resolve
references to that argument to an explicit undefined value.  The current code
leaves the reference to the template argument as it is, which causes an
assertion failure later when the definition of the template argument is
removed.

0f846dbb3e Make X86-64 in the Large model always emit 64-bit calls. 
The large code model is documented at
http://www.x86-64.org/documentation/abi.pdf and says that calls should
assume their target doesn't live within the 32-bit pc-relative offset
that fits in the call instruction.

To do this, we turn off the global-address->target-global-address
conversion in X86TargetLowering::LowerCall(). The first attempt at
this broke the lazy JIT because it can separate the movabs(imm->reg)
from the actual call instruction. The lazy JIT receives the address of
the movabs as a relocation and needs to record the return address from
the call; and then when that call happens, it needs to patch the
movabs with the newly-compiled target. We could thread the call
instruction into the relocation and record the movabs<->call mapping
explicitly, but that seems to require at least as much new
complication in the code generator as this change.

To fix this, we make lazy functions _always_ go through a call
stub. You'd think we'd only have to force lazy calls through a stub on
difficult platforms, but that turns out to break indirect calls
through a function pointer. The right fix for that is to distinguish
between calls and address-of operations on uncompiled functions, but
that's complex enough to leave for someone else to do.

Another attempt at this defined a new CALL64i pseudo-instruction,
which expanded to a 2-instruction sequence in the assembly output and
was special-cased in the X86CodeEmitter's emitInstruction()
function. That broke indirect calls in the same way as above.

This patch also removes a hack forcing Darwin to the small code model.
Without far-call-stubs, the small code model requires things of the
JITMemoryManager that the DefaultJITMemoryManager can't provide.

Thanks to echristo for lots of testing!

160f3b9191 Support GoogleTest's "typed tests" 
(http://code.google.com/p/googletest/wiki/GoogleTestAdvancedGuide#Typed_Tests)
in lit.py.  These tests have names like "ValueMapTest/0.Iteration", which broke
when lit.py os.path.join()ed them onto the path and then assumed it could
os.path.split() them back off.  This patch shifts path components from the
testPath to the testName until the testPath exists.

Several instances of PluginPriority in a single file most probably signifies a
programming error.

8ea3f4a592 Add instruction flags: hasExtraSrcRegAllocReq and hasExtraDefRegAllocReq. When 
set, these flags indicate the instructions source / def operands have special
register allocation requirement that are not captured in their register classes.
Post-allocation passes (e.g. post-alloc scheduler) should not change their
allocations. e.g. ARM::LDRD require the two definitions to be allocated
even / odd register pair.
