Sorry for the delay,

I applied the patches after some cleanups.  Please keep code within 80 
columns, please don't use nested ?: expressions without parens, and please 
be careful about indentation.  Please verify that mainline CVS has 
everything you think it should.

The one hunk I didn't apply was this one:

      case MVT::f64:
-      if (isVarArg && isPPC64) {
+      if (isVarArg || isPPC64) {
          // Float varargs need to be promoted to double.
          if (Arg.getValueType() == MVT::f32)
            Arg = DAG.getNode(ISD::FP_EXTEND, MVT::f64, Arg);

This changes the darwin/ppc ABI.  It's not clear to me that this was 
intended, so I just left it out.

Thanks a lot for these patches.  How well does linux/ppc work now?
