I bootstrapped succesfully on my m68k-next-nextstep3 with this
patch; running c-torture-1.45 shows no regression w.r.t. to previous
egcs-1.1 prerelease snapshots.
There are three reasons why I think it's useful for _me_ to test
this patch (apart from the fact that I think it's a sound way of
1. The m68k, like the ix86, has few registers, so there will be an
2. The m68k, unlike the ix86, has postincrement and predecrement
addressing modes - this has to be tested also (see the REG_INC
parts of the patch).
3. Using the Fortran Frontend guarantees different "forcing" of
the backend and the reload pass.
