Subject: 64-bit integers on IA32
Date: Mon, 02 Sep 2002 10:46:00 -0000	[thread overview]
Message-ID: <008601c252a8$9df66830$0808d30a@amadeus> (raw)

I was told half a year ago that the reason that gcc performing as well with
64-bit integers on IA32 as some other compilers (Intel, MS)  was the the
register-pair used for holding the 64-bit integer, was thought of as a whole
by the compiler, which messed with gcc's register scheduling, or something
like that. Has that and/or related problems been solved in the meantime, or
will they be solved in any near future?

Thanks in advance,
David
