5a4ed7e8ab Implement the last major missing piece in the DAG isel generator: when emitting
a pattern match, make sure to emit the (minimal number of) type checks that
verify the pattern matches this specific instruction.  This allows FMA32
patterns to not match double expressions for example.

3aa7a188b9 Now that we have int/fp lattice values, implement the SDTCisOpSmallerThanOp
type constraint.  This lets tblgen realize that it doesn't need any dynamic
type checks for fextend/fround on PPC (and many other targets), because there
are only two fp types.

81047cdfc0 Implement a couple of new (important) features.
1. If an operation has to be int or fp and the target only supports one
   int or fp type, relize that the op has to have that type.
2. If a target has operations on multiple types, do not emit matching code
   for patterns involving those operators, since we do not emit the code to
   check for them yet.  This prevents PPC from generating FP ops currently.

Also move some code around into more logical places.

31a9d318a3 Teach tblgen to build permutations of instructions, so that the target author
doesn't have to specify them manually.  It currently handles associativity,
e.g. knowing that (X*Y)+Z  also matches  X+(Y*Z)  and will be extended in
the future.

It is smart enough to not introduce duplicate patterns or patterns that can
never match.

0231f57a46 Emit an error if instructions or patterns are defined but can never match.
Currently we check that immediate values live on the RHS of commutative
operators.  Defining ORI like this, for example:

def ORI   : DForm_4<24, (ops GPRC:$dst, GPRC:$src1, u16imm:$src2),
                    "ori $dst, $src1, $src2",
                    [(set GPRC:$dst, (or immZExt16:$src2, GPRC:$src1))]>;

results in:

tblgen: In ORI: Instruction can never match: Immediate values must be on the RHS of commutative operators!

Inst pattern EQV:       (set GPRC:i32:$rT, (xor (xor GPRC:i32:$rA, GPRC:i32:$rB), (imm)<<Predicate_immAllOnes>>))

we now fully infer:

Inst pattern EQV:       (set:void GPRC:i32:$rT, (xor:i32 (xor:i32 GPRC:i32:$rA, GPRC:i32:$rB), (imm:i32)<<Predicate_immAllOnes>>))

The only code it generates currently is some boilerplate code for things

be checked in as any other LLVM source so that platforms without convenient
access to flex/bison can be compiled. From now on, if you change a .y or

b312f4d374 When emitting implicit use/def lists, only emit each unique list once. Though
LLVM is able to merge identical static const globals, GCC isn't, and this caused
some bloat in the generated data.  This has a marginal effect on PPC, shrinking
the implicit sets from 10->4, but shrinks X86 from 179 to 23, a much bigger
reduction.

This should speed up the register allocator as well by reducing the dcache
footprint for this static data.

078cda0bb3 This is the final big of factoring. This shares cases in suboperand
differences, which means that identical instructions (after stripping off
the first literal string) do not run any different code at all.  On the X86,
this turns this code:

    switch (MI->getOpcode()) {
    case X86::ADC32mi: printOperand(MI, 4, MVT::i32); break;
    case X86::ADC32mi8: printOperand(MI, 4, MVT::i8); break;
    case X86::ADC32mr: printOperand(MI, 4, MVT::i32); break;
    case X86::ADD32mi: printOperand(MI, 4, MVT::i32); break;
    case X86::ADD32mi8: printOperand(MI, 4, MVT::i8); break;
    case X86::ADD32mr: printOperand(MI, 4, MVT::i32); break;
    case X86::AND32mi: printOperand(MI, 4, MVT::i32); break;
    case X86::AND32mi8: printOperand(MI, 4, MVT::i8); break;
    case X86::AND32mr: printOperand(MI, 4, MVT::i32); break;
    case X86::CMP32mi: printOperand(MI, 4, MVT::i32); break;
    case X86::CMP32mr: printOperand(MI, 4, MVT::i32); break;
    case X86::MOV32mi: printOperand(MI, 4, MVT::i32); break;
    case X86::MOV32mr: printOperand(MI, 4, MVT::i32); break;
    case X86::OR32mi: printOperand(MI, 4, MVT::i32); break;
    case X86::OR32mi8: printOperand(MI, 4, MVT::i8); break;
    case X86::OR32mr: printOperand(MI, 4, MVT::i32); break;
    case X86::ROL32mi: printOperand(MI, 4, MVT::i8); break;
    case X86::ROR32mi: printOperand(MI, 4, MVT::i8); break;
    case X86::SAR32mi: printOperand(MI, 4, MVT::i8); break;
    case X86::SBB32mi: printOperand(MI, 4, MVT::i32); break;
    case X86::SBB32mi8: printOperand(MI, 4, MVT::i8); break;
    case X86::SBB32mr: printOperand(MI, 4, MVT::i32); break;
    case X86::SHL32mi: printOperand(MI, 4, MVT::i8); break;
    case X86::SHLD32mrCL: printOperand(MI, 4, MVT::i32); break;
    case X86::SHR32mi: printOperand(MI, 4, MVT::i8); break;
    case X86::SHRD32mrCL: printOperand(MI, 4, MVT::i32); break;
    case X86::SUB32mi: printOperand(MI, 4, MVT::i32); break;
    case X86::SUB32mi8: printOperand(MI, 4, MVT::i8); break;
    case X86::SUB32mr: printOperand(MI, 4, MVT::i32); break;
    case X86::TEST32mi: printOperand(MI, 4, MVT::i32); break;
    case X86::TEST32mr: printOperand(MI, 4, MVT::i32); break;
    case X86::TEST8mi: printOperand(MI, 4, MVT::i8); break;
    case X86::XCHG32mr: printOperand(MI, 4, MVT::i32); break;
    case X86::XOR32mi: printOperand(MI, 4, MVT::i32); break;
    case X86::XOR32mi8: printOperand(MI, 4, MVT::i8); break;
    case X86::XOR32mr: printOperand(MI, 4, MVT::i32); break;
    }

into this:

    switch (MI->getOpcode()) {
    case X86::ADC32mi:
    case X86::ADC32mr:
    case X86::ADD32mi:
    case X86::ADD32mr:
    case X86::AND32mi:
    case X86::AND32mr:
    case X86::CMP32mi:
    case X86::CMP32mr:
    case X86::MOV32mi:
    case X86::MOV32mr:
    case X86::OR32mi:
    case X86::OR32mr:
    case X86::SBB32mi:
    case X86::SBB32mr:
    case X86::SHLD32mrCL:
    case X86::SHRD32mrCL:
    case X86::SUB32mi:
    case X86::SUB32mr:
    case X86::TEST32mi:
    case X86::TEST32mr:
    case X86::XCHG32mr:
    case X86::XOR32mi:
    case X86::XOR32mr: printOperand(MI, 4, MVT::i32); break;
    case X86::ADC32mi8:
    case X86::ADD32mi8:
    case X86::AND32mi8:
    case X86::OR32mi8:
    case X86::ROL32mi:

    case X86::SUB32mi8:
    case X86::TEST8mi:
    case X86::XOR32mi8: printOperand(MI, 4, MVT::i8); break;
    }

After this, the generated asmwriters look pretty much as though they were
generated by hand.  This shrinks the X86 asmwriter.inc files from 55101->39669
and 55429->39551 bytes each, and PPC from 16766->12859 bytes.

eee6c31449 Implement *even more* factoring. In particular, if all of the instruction
strings starts out with a constant string, we emit the string first, using
a table lookup (instead of a switch statement).

Because this is usually the opcode portion of the asm string, the differences
between the instructions have now been greatly reduced.  This allows many
more case statements to be grouped together.

This patch also allows instruction cases to be grouped together when the
instruction patterns are exactly identical (common after the opcode string
has been ripped off), and when the differing operand is a MachineInstr
operand that needs to be formatted.

The end result of this is a mean and lean generated AsmPrinter!

a030a47a51 Implement factoring of instruction pattern strings. In particular, instead of
emitting code like this:

  case PPC::ADD: O  << "add ";  printOperand(MI, 0, MVT::i64); O  << ", ";  prin
tOperand(MI, 1, MVT::i64); O  << ", ";  printOperand(MI, 2, MVT::i64); O  << '\n
'; break;
  case PPC::ADDC: O  << "addc ";  printOperand(MI, 0, MVT::i64); O  << ", ";  pr
intOperand(MI, 1, MVT::i64); O  << ", ";  printOperand(MI, 2, MVT::i64); O  << '
\n'; break;
  case PPC::ADDE: O  << "adde ";  printOperand(MI, 0, MVT::i64); O  << ", ";  pr
intOperand(MI, 1, MVT::i64); O  << ", ";  printOperand(MI, 2, MVT::i64); O  << '
\n'; break;
...

Emit code like this:

  case PPC::ADD:
  case PPC::ADDC:
  case PPC::ADDE:
  ...
    switch (MI->getOpcode()) {
    case PPC::ADD: O << "add "; break;
    case PPC::ADDC: O << "addc "; break;
    case PPC::ADDE: O << "adde "; break;
    ...
    }
    printOperand(MI, 0, MVT::i64);
    O << ", ";
    printOperand(MI, 1, MVT::i64);
    O << ", ";
    printOperand(MI, 2, MVT::i64);
    O << "\n";
    break;

This shrinks the PPC asm writer from 24785->15205 bytes (even though the new
asmwriter has much more whitespace than the old one), and the X86 printers shrink
quite a bit too.  The important implication of this is that GCC no longer hits swap
when building the PPC backend in optimized mode.  Thus this fixes PR448.

67cbd23ad5 Seperate asmstring parsing from emission. This allows the code to be simpler
and more understandable.  It also allows us to do simple things like fold
consequtive literal strings together.  For example, instead of emitting this
for the X86 backend:

  O  << "adc" << "l" << " ";

we now generate this:

  O << "adcl ";

*whoa* :)

This shrinks the X86 asmwriters from 62729->58267 and 65176->58644 bytes
for the intel/att asm writers respectively.

2. Fix a bug where the lib directory specified also had to be cwd
3. Weight the output so archive->archive edges are shorter
4. Generate two different graphs: one for libraries, one for objects.
5. Adjust the properties of the graphs till it looks nice.
