Steve Naroff 31daee11be Tweak Sema::DefaultArgumentPromotion() to call UsualUnaryConversions(). This makes sure function calls that don't have a prototype get the default function/array conversion.

Scott Michel 167502a508 Fix to bug 1951: tblgen gratuitously renames variables when no temporary was
generated. This feature would only show up in fairly complex patterns, such
as this one in CellSPU:

  def : Pat<(add (SPUhi tconstpool:$in, 0), (SPUlo tconstpool:$in, 0)),
	    (IOHLlo (ILHUhi tconstpool:$in), tconstpool:$in)>;

which generated the following emit code:

SDNode *Emit_0(const SDOperand &N, unsigned Opc0, unsigned Opc1, MVT::ValueType VT0, MVT::ValueType VT1) DISABLE_INLINE {
  SDOperand N0 = N.getOperand(0);
  SDOperand N00 = N0.getOperand(0);
  SDOperand N01 = N0.getOperand(1);
  SDOperand N1 = N.getOperand(1);
  SDOperand N10 = N1.getOperand(0);
  SDOperand N11 = N1.getOperand(1);
  SDOperand Tmp3(CurDAG->getTargetNode(Opc0, VT0, N00), 0);
  return CurDAG->SelectNodeTo(N.Val, Opc1, VT1, Tmp3, Tmp2); /* Tmp2 s/b N00 */
}

Tested against the test suites without incident.

Scott Michel ceae3bbf4d Overhaul Cell SPU's addressing mode internals so that there are now
only two addressing mode nodes, SPUaform and SPUindirect (vice the
three previous ones, SPUaform, SPUdform and SPUxform). This improves
code somewhat because we now avoid using reg+reg addressing when
it can be avoided. It also simplifies the address selection logic,
which was the main point for doing this.

Also, for various global variables that would be loaded using SPU's
A-form addressing, prefer D-form offs[reg] addressing, keeping the
base in a register if the variable is used more than once.

Ted Kremenek 17a739681c Some additional cleanups with method names.
Renamed ExprValue to RValue, as all expression values are RValues, and this
keeps with the C terminology (renamed old "RValue" class to "NonLValue").

Introduced "ConcreteInt", a class that represents a concrete, integer
constant as an RValue.

Temporarily removed classes to represent set of possible constants and set of !=
constants. Will replace with a more general class representing a set of
constraints.

Added some foundational code to track "symbolic" values, which are used to
accrue constraints on an abstract value that is shared between multiple
variables.  e.g:

   x = y;      // at this point "x" and "y" share the same "value"
   if (x > 1) 
     ...       // at this point, the value shared by "x" and "y" is "> 1".

Chris Lattner 888560d62c Implement some dag combines that allow doing fneg/fabs/fcopysign in integer
registers if used by a bitconvert or using a bitconvert.  This allows us to
avoid constant pool loads and use cheaper integer instructions when the
values come from or end up in integer regs anyway.  For example, we now 
compile CodeGen/X86/fp-in-intregs.ll to:

_test1:
	movl	$2147483648, %eax
	xorl	4(%esp), %eax
	ret
_test2:
	movl	$1065353216, %eax
	orl	4(%esp), %eax
	andl	$3212836864, %eax
	ret

Instead of:
_test1:
	movss	4(%esp), %xmm0
	xorps	LCPI2_0, %xmm0
	movd	%xmm0, %eax
	ret
_test2:
	movss	4(%esp), %xmm0
	andps	LCPI3_0, %xmm0
	movss	LCPI3_1, %xmm1
	andps	LCPI3_2, %xmm1
	orps	%xmm0, %xmm1
	movd	%xmm1, %eax
	ret

bitconverts can happen due to various calling conventions that require
fp values to passed in integer regs in some cases, e.g. when returning
a complex.
