in that section.)  Just to make sure, the change per se is fine; I
just think it might be "Support for", here and in other parts of the
patch.

+    <li>New function attribute <code>callee_pop_aggregate</code> allows
+    to specify if caller, or callee is responsible to pop aggregate
+    return pointer value from stack.</li>

Omit the comma before "or" and add "the" before "aggregate" and "stack".

+<h3 id="windows">Windows x86/x86_64</h3>
+  <ul>
+    <li>Initial support of decimal floating point.</li>

"for" (also in several further items)

+    <li>Support of hot-patchable function prologue via attribute
+    <code>ms_hook_prologue> also for x86_64 architecture.</li>

So, we have this for x86 (32-bit already)?  Then we could say "for
x86-64 in addition to 32-bit x86" to make that more clear.

+    <li>Improvment of stack-probing and stack-allocation mechanism.</li>

"Improvements"
"mechanisms"

+    <li>Support of push/pop-macro pragma as preprocessor command.</li>

Can you provide a concrete code example?

> Ok for commit?

Yes, modulo the changes above -- and please omit those unrelated hunks
that only change whitespace in other parts of the page.

Thanks!

Yes, this feature depends on TImode >= 128-bit support and has nothing
to do with IA. It isn't related to the __float128 feature, as __int128
is an integer scalar ISO-C extension type and not a floating point
one.

Thanks for review. I will adjust text later this evening (I don't have
access from office to wwwdoc CVS).

Regards,
Kai

Ahem, of course __float128 and __int128 are _slightly_ different data
types.  How embarrassing.  /me crawls back into my cave now.
