Treat the label for the first @llvm.dbg.stoppoint the same way as the dbg_func_start label. Make sure nothing else is inserted before them.
...
Note this solution might be somewhat fragile since ISD::LABEL may be used for other
purposes. If that ends up to be an issue, we may need to introduce a different node
for debug labels.

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.

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 */
}

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.
