The GNAT frontend uses its own routines for unlimited precision
evaluation of rational expressions, as this is required by the
language standard. It is not that hard to do, and there would
be no reason why you couldn't steal the GNAT packages and
translate them to fortran or C.

The packages for universal integer and universal real are 2400 and 1400
lines respectively, of which about half blank or comment.

On the other hand, if more frontends are going to use this it might make
sense to include GMP...

I suspect if we did this, gmp would need to be hosted on gcc.gnu.org as well
(though it would be useful to move gcc into the common tree with binutils and
gdb if we do).

Using GMP in a GCC Frontend.

[Toon Moene]

L.S.,

After ample discussion on the GNU Fortran 95 mailing list (see the URL
given below), we've come to the conclusion that we need the GNU Multi
Precision Library for some compiler arithmetic (in addition to the
functions offered by floatlib.c).

However, AFAIK, that would mean that the Fortran 95 frontend would be
the first to depend on such an "outside" library.

Is that a problem - and if so, why ?

Thanks in advance for offering any insight ...
