--- Comment #13 from Carl E Love <cel at us dot ibm.com> ---
Yes, I hadn't considered they might use different calling conventions.=20
Checking the 64-bit ABI, it says:

the IEEE binary 128-bit quad precision type is IEEE 128-bit quad-precision
float, page 8. Page 39 says "Parameters and function results in IEEE BINARY=
 128
QUADRUPLE PRECISION format shall be passed in a single 128-bit vector regis=
ter
as if they were vector values."=20=20

The IBM extended precision format says, "Parameters and function results in=
 the
IBM EXTENDED PRECISION format with a pair of two double-precision
floating-point values shall be passed in two successive floating-point
registers."

So yea, we need to consider the differences.  Perhaps that will fix the
printing issue I had???
