Hi,
I'd like to make a backend which would have 48 bits for 'long' type.
(32 for int and 64 for long long).
I have tried to define:
#define LONG_TYPE_SIZE 48
That's not a partial integer mode; PDImode would have the same size as DImode,
just not all bits would be sign

I have tried to define:

and one of:
INT_MODE (PDI, 6);
PARTIAL_INT_MODE (DI);
Unfortunately, trying to compile a program, I see that the backend
still uses SImo

That could well be. I now c
Toon,
I would suspect this boost is from the series of changes
to "Update default arch for x86" from HJ Lu. This should now
have -msse2 in use as the default (except on darwin where

L.S.,
In the past week, changes to GNU Fortran / GCC brought me a 4 minute
gain in a 3.5 hour weather forecast (run 4 times a day on my home
computer - see http://moene.org/~hirlam/)
4 minutes on 210 minutes is ~ 2 % - not bad for such a diverse code.
Without digging deeper in it (for which
