Work in progress. This patch *fixes* x86-64 calls which are modelled as StructRet but really should be return in registers, e.g. _Complex long double, some 128-bit aggregates. This is a short term solution that is necessary only because llvm, for now, cannot model i128 nor call's with multiple results.
...
Status: This only works for direct calls, and only the caller side is done. Disabled for now.

When expanding an operand, it's not the result value

type that matters but the operand type. This fixes
2008-01-08-IllegalCMP.ll which crashed with the new
legalize infrastructure because SETCC with result
type i8 and operand type i64 was being custom expanded
by the X86 backend. With this fix, the gcc build gets
as far as the first libcall.

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.

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.
