4ac7a0ca8f reject patterns that have dead named arguments in the input pattern 
this is tidier and can find bugs.

967d54ae04 reject patterns that mention a name in the destination pattern 
but not in the input.  Previously, this would trigger an abort
late in the isel logic.

3e22f2d489 add a new Push2 opcode for targets (like cellspu) which have 
ridiculously ginormous patterns and need more than one byte
of displacement for encodings.  This fixes CellSPU/fdiv.ll.
SPU is still doing something else ridiculous though.

20df2420f7 Change ComplexPattern handling to push the node being matched as 
well as the operands produced when the pattern is matched.  This
allows CheckSame to work correctly when matching replicated 
names involving ComplexPatterns.  This fixes a bunch of MSP430 
failures, we're down to 13 failures, two of which are
due to a sched bug.

1f2ed5fe7e When matching patterns that have a complex pattern as their root, make 
sure to only run the complex pattern on nodes where the target opts in.
This patch only handles targets with one opcode specified so far, but
fixes 16 failures, only 34 left.

565a6f9480 fix most of the failures in the x86 suite by handling multiple 
result nodes correctly.  Note that this includes a horrible hack
in DAGISelHeader which cannot be fixed reasonably without 
eliminating (parallel) from input patterns.  That, in turn,
can't be done until we support writing multiple result patterns
for the X86and_flag and related multiple-result nodes.

8e946bea14 Lots of improvements to the new dagisel emitter. This gets it to 
the point where it is to the 95% feature complete mark, it just
needs result updating to be done (then testing, optimization 
etc).

More specificallly, this adds support for chain and flag handling
on the result nodes, support for sdnodexforms, support for variadic
nodes, memrefs, pinned physreg inputs, and probably lots of other
stuff.

In the old DAGISelEmitter, this deletes the dead code related to
OperatorMap, cleans up a variety of dead stuff handling "implicit
remapping" from things like globaladdr -> targetglobaladdr (which
is no longer used because globaladdr always needs to be legalized),
and some minor formatting fixes.

014bf215c3 Split SelectionDAGISel::IsLegalAndProfitableToFold to 
IsLegalToFold and IsProfitableToFold. The generic version of the later simply checks whether the folding candidate has a single use.

This allows the target isel routines more flexibility in deciding whether folding makes sense. The specific case we are interested in is folding constant pool loads with multiple uses.

da272d1a70 Check in the first big step of rewriting DAGISelEmitter to 
produce a table based matcher instead of gobs of C++ Code.

Though it's not done yet, the shrinkage seems promising,
the table for the X86 ISel is 75K and still has a lot of 
optimization to come (compare to the ~1.5M of .o generated
the old way, much of which will go away).

The code is currently disabled by default (the #if 0 in
DAGISelEmitter.cpp).  When enabled it generates a dead
SelectCode2 function in the DAGISel Header which will
eventually replace SelectCode.

There is still a lot of stuff left to do, which are
documented with a trail of FIXMEs.

570a4a5d9c 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.

ce8febefa5 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.

9898671a74 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.

d4f195999a 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.

7c422ac216 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.

8ed9f51663 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.

ead2dacc9e 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.

2214dc0764 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.

d1ba06bf13 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!

799d697bf8 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

even / odd register pair.

c76909abfe Improve MachineMemOperand handling. 
- Allocate MachineMemOperands and MachineMemOperand lists in MachineFunctions.
   This eliminates MachineInstr's std::list member and allows the data to be
   created by isel and live for the remainder of codegen, avoiding a lot of
   copying and unnecessary translation. This also shrinks MemSDNode.
 - Delete MemOperandSDNode. Introduce MachineSDNode which has dedicated
   fields for MachineMemOperands.
 - Change MemSDNode to have a MachineMemOperand member instead of its own
   fields with the same information. This introduces some redundancy, but
   it's more consistent with what MachineInstr will eventually want.
 - Ignore alignment when searching for redundant loads for CSE, but remember
   the greatest alignment.

Target-specific code which previously used MemOperandSDNodes with generic
SDNodes now use MemIntrinsicSDNodes, with opcodes in a designated range
so that the SelectionDAG framework knows that MachineMemOperand information
is available.

5d6a05f4d4 reimplement the regex matching strategy by building a single 
regex and matching it instead of trying to match chunks at a time.
Matching chunks at a time broke with check lines like 
  CHECK: foo {{.*}}bar
because the .* would eat the entire rest of the line and bar would
never match.

Now we just escape the fixed strings for the user, so that something
like:
  CHECK: a() {{.*}}???
is matched as:
  CHECK: {{a\(\) .*\?\?\?}}
transparently "under the covers".

c5ea263a23 remove DebugLoc from MCInst and eliminate "Comment printing" from 
the MCInst path of the asmprinter.  Instead, pull comment printing
out of the autogenerated asmprinter into each target that uses the
autogenerated asmprinter.  This causes code duplication into each
target, but in a way that will be easier to clean up later when more
asmprinter stuff is commonized into the base AsmPrinter class.

This also fixes an xcore strangeness where it inserted two tabs
before every instruction.

634cca377a hoist the call to processDebugLoc out of the generated 
asm printer into the "printInstruction" routine.  This
fixes a problem where the experimental asmprinter would
drop debug labels in some cases, and fixes issues on ppc/xcore
where pseudo instructions like "mr" didn't get debug locs properly.

It is annoying that this moves the call from one place into each
target, but a future set of more invasive refactorings will fix
that problem.

9c0c3bf1ec Teach googletest to use raw_ostream instead of just std::ostream. 
This can break when there are implicit conversions from types raw_ostream
understands but std::ostream doesn't, but it increases the number of cases that

cdfa01bf0f PR4795: Remove EEVT::isFP, isInt and isVec types used by TableGen's type 
inferencing.  As far as I can tell, these are equivalent to the existing
MVT::fAny, iAny and vAny types, and having both of them makes it harder
to reason about and modify the type inferencing code.

The specific problem in PR4795 occurs when updating a vAny type to be fAny
or iAny, or vice versa.  Both iAny and fAny include vector types -- they
intersect with the set of types represented by vAny.  When merging them,
choose fAny/iAny to represent the intersection.  This is not perfect, since
fAny/iAny also include scalar types, but it is good enough for TableGen's
type inferencing.

20a709f9de Revert 76080. This broke some powerpc cross compiles. 
It also makes the llvmCore build dependent on whatever version of llvm-gcc
happens to be installed on the build machine.
