In the Intel Itanium Architecture Software Developer's Manual, Volume 1:Application Architecture, Rev 2.1 Dated October 2002, in section 5.1, Data Types and Formats of the Floating-point Programming Model chapter, it states:
A seventh data type, IEEE-style quad precision, is supported by software routines. A future architecture extension may include additional support for the quad-precision real type.
Question: Are these software routines available for the Itanium 2? If so, where does one gain access to them? Will these future architecture extensions be included in Madison?
