/xxx/gnu/gcc-3.3/gcc/gcc/testsuite/g77.f-torture/compile/980310-3.f:255: error: 
insn does not satisfy its constraints:
(insn 4745 228 241 3 (set (mem/s/j:DF (plus:DI (reg/f:DI %r23 [2850])
                (mult:DI (reg:DI %r10 [79])
                    (const_int 8 [0x8]))) [0 (* wk) S8 A64])
        (reg:DF %r21)) 116 {*pa.md:3595} (nil)
    (nil))

This failure was introduced by the following patch:

2003-11-02  Richard Sandiford  <rsandifo@redhat.com>

        * reload.c: Include target.h.
        (find_reloads): If an alternative will force a constant into memory,
        count an extra reload if constant pool symbols are not valid
        addresses.  If an alternative uses memory to move values between
        registers, count the move as two reloads rather than one.

The insn doesn't match its constraints because only floating stores
support scaled indexed stores.  Integer stores don't.
