We added __float128 suppor to IA-32/IA64 in gcc 4.4. This patch
updates gcc-4.4/changes.html. OK to check in?
Thanks.

+<h3>IA-32/IA64</h3>
+ <ul>
+ <li>Support for <code>__float128</code> (TFmode) IEEE quad type and
+ corresponding TCmode IEEE complex quad type is available
+ via the soft-fp library on <code>IA-32/IA64</code> targets.
+ This includes basic arithmetic operations (addition, subtraction,
+ negation, multiplication and division) on <code>__float128</code>
+ real and TCmode complex values, the full set of IEEE comparisons
+ between <code>__float128</code> values, conversions to and from
+ <code>float</code>, <code>double</code> and <code>long double</code>
+ floating point types, as well as conversions to and from
+ <code>signed</code> or <code>unsigned</code> integer,
+ <code>signed</code> or <code>unsigned long</code> integer and
+ <code>signed</code> or <code>unsigned</code> quad (TImode)
+ (<code>IA64</code> only) integer
+ types. Additionally, all operations generate the full set of IEEE
+ exceptions and support the full set of IEEE rounding modes.</li>
