1d7435f478 * Make sure complex pattern operands are selected first since their select
functions can return false and causing the instruction pattern match to fail.
* Code clean up.

d11d31e0bd Added support for ComplexPattern. These are patterns that require C++ pattern
matching code that is not currently auto-generated by tblgen, e.g. X86
addressing mode. Selection routines for complex patterns can return multiple operands, e.g. X86 addressing mode returns 4.

cf4f349880 * Commit the fix (by Chris) for a tblgen type inferencing bug.
* Enhanced tblgen to handle instructions which have chain operand and writes a
chain result.
* Enhanced tblgen to handle instructions which produces no results. Part of
the change is a temporary hack which relies on instruction property (e.g.
isReturn, isBranch). The proper fix would be to change the .td syntax to
separate results dag from ops dag.

9c3508e1ab Teach tblgen to accept register source operands in patterns, e.g.
def SHL8rCL  : I<0xD2, MRM4r, (ops R8 :$dst, R8 :$src),
                 "shl{b} {%cl, $dst|$dst, %CL}",
                 [(set R8:$dst, (shl R8:$src, CL))]>, Imp<[CL],[]>;

This generates a CopyToReg operand and added its 2nd result to the shl as
a flag operand.

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.

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!

a6d21c974c Implement a complete type inference system for dag patterns, based on the
constraints defined in the DAG node definitions in the .td files.  This
allows us to infer (and check!) the types for all nodes in the current
ppc .td file.  For example, instead of:

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>>))

from:  (set GPRC:$rT, (not (xor GPRC:$rA, GPRC:$rB)))
