How does that cripple my XEmacs? It might cripple my system, but not XEmacs. The same way you could say that image support, variable width fonts, variable height lines and all that cruft "cripples" my XEmacs because of an "enormous memory overhead". > We have two competing primitive types.

There must be other ways of dealing with chars. We've lived with 8-bit and 19-bit (19! what a number!) chars for quite a while. Surely a scheme can be devised for them to be thirty bit. No "scheme" will buy you 31-bit integers except the current one, and bignums. And bignums are hard. > > I can already hear people saying, "Oh, you need larger buffers? > > Why, compile without Mule -- everyone sensible does that." > > No, the answer would be "use a 64-bit system everyone sensible does > that". I constructed the hypothetical question and stand by the hypothetical answer. I'm sure people *do* think that way. Or do you think they will buy an alpha or ultrasparc rather than compile --without-mule?

I have tried 600M buffers, and things worked reasonably fast -- i.e. slow as hell, but workable in case of emergency. I still don't understand your remark about O(n^2) operations, though.

GCC 2.95 good news 25 years, 6 months

Jan Vroonhof

I just build 21.1.3-latin-2 with the latest snapshot for GCC 2.95 on Sparc and so far there seem to be no problems. Jan

Before I start scaring you off: Would it be difficult to have a separate "unsigned integer type?". That could still go up to 2^30-1. Hrvoje Niksic <hniksic(a)srce.hr> writes: > That would be the worst possible option. Mule should bring new > functionality, not cripple XEmacs. No released XEmacs has that functionality remember? Note that currently you cripple anyway your XEmacs when you switch it on, you get an enormous memory overhead on all lisp types. I wouldn't loose any sleep over 1-bit of integer precision (unless we were going from 32 to 31). We have two competing primitive types. One of them is more or less naturally limited to 31-bits and for the other the cut-off is arbitrary. We have only one with 31-bits available, you choose? > I can already hear people saying, > "Oh, you need larger buffers? Why, compile without Mule -- everyone > sensible does that." No, the answer would be "use a 64-bit system everyone sensible does that". I think the number of cases where you want to edit a 0.75 G file in XEmacs is extremely low, certainly much lower than the # of people profiting from full UCS-4 transparency (probably also not a big group). > > You do not really want to do O(n^2) operations on 1 Gbyte buffers > > anyway. > > You don't. Why do you ask? Because I think editing a 1 Gbyte buffer in a Mule XEmacs will be so slow that it doesn't matter much anyway. Jan

As Kyle noticed, buffer sizes will suffer. Currently an Emacs buffer can accept up to 1G of characters. With the swap, it will be "only" 512M. Believe it or not, there _will_ be people hurt by the difference. That the classical Emacsen didn't even have 30 bits is not a good argument. I've written a NEWS entry that says: ** It is now possible to build XEmacs with support for 31-bit Lisp integers (normally, Lisp integers are only 28 bits wide on 32-bit machines.) Configure with --use-minimal-tagbits to test. With this change, the maximum buffer size on 32-bit machines is increased from 128M to 1G. This setting will be made default in a future XEmacs version. I wouldn't like to lose this. Finally, I do need integers as large as I can get, even when it's not the full 32 bits. We'll have to find another way for dealing with UCS-4.
