gcc version 3.0.4
>Description:
On hppa linux (32bits), I try to implement evms tools to manage lvm. That works without problems until release 1.1.0 which used put_user(x,ptr) with x a 64bits long int (which seems to became 'legal'). But under hppa linux this code is not yet supported with a 32bits kernel (and it is written in asm extension).

Even thought mips 32bits implements it. There (linux/include/asm-mips/uaccess.h) I discover that it is possible with some prefix (D, M, L, IIRC) to access to the two (32bits) int part of a 64bits long int.

So I just try the small attached example to see if it is also foreseen with hppa release. As it failled by reporting me: Internal compiler error in print operand, at config/pa/pa.c
please submit a full bug report... , I do it because I reach to implement something working with pointer but it broken the  structure of the actual implementation and makes it also more complexe.

Thanks in advance for your attention and futher help,
    Joel
