8300ae66d1 For instructions which produce no result, e.g. store, chain's Resno == 0.

aaec1f6faa Add a new SDTCisPtrTy constraint, which indicates that an operand must have 
the same type as the pointer type for a target.

9586e87904 * Do not allow nodes which produce chain results (e.g. loads) to be folded if 
it has more than one real use (non-chain uses).
* Record folded chain producing node in CodeGenMap.
* Do not fold a chain producing node if it has already been selected as an
  operand of a chain use.

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.

811a41a87c Support multiple ValueTypes per RegisterClass, needed for upcoming vector 
work.  This change has no effect on generated code.

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.

466eaefd38 Stop checking the ValueType of the CodeGenInstruction. Instead, use the 
ValueType from the RegisterClass or Operands.  This step is necessary to
allow RegisterClasses to have multiple ValueTypes.

e42da1ae45 Let people who run the nightly tester specify paths to external tests, instead 
of having to hack the nightly tester script itself.

as an example, I use the following for my machine:

$HOME/llvm/utils/NightlyTest.pl -parallel -release -enable-llcbeta \
     -spec2000path /Volumes/ProjectsDisk/cvs/benchmarks/speccpu2000-llvm/benchspec/ \
     -povraypath /Volumes/ProjectsDisk/cvs/benchmarks/povray31 \
     -namdpath /Volumes/ProjectsDisk/cvs/benchmarks/namd
