If you follow Brad Lucier's advice and start reading at:
http://gcc.gnu.org/ml/gcc-patches/2001-03/msg00382.html
and then completely exhaust the "Follow-ups" sequence, you'll arrive at
my
http://gcc.gnu.org/ml/gcc-patches/2001-03/msg00481.html
[ Note: this takes about a dozen follow-ups ]
"You [i.e, Brad] reach the same conclusion I did in my mail on the
19th of July 1999 to gcc@gcc.gnu.org with Subject: "ia32 and IEEE-754
conformance." (see: http://gcc.gnu.org/ml/gcc/1999-07n/msg00696.html),
although I agree your 0 .. 2 items sum it up more clearly.
The overall conclusion at that time was that this would be useful to
add to GCC, but no-one was stepping forward to do the work.
That still is the case."
Hope this helps,
