*/
/*
* The alpha chip doesn't provide hardware division, so we have to do it
* by hand. The compiler expects the functions
*
* __divqu: 64-bit unsigned long divide
* __remqu: 64-bit unsigned long remainder
* __divqs/__remqs: signed 64-bit
* __divlu/__remlu: unsigned 32-bit
* __divls/__remls: signed 32-bit
*
* These are not normal C functions: instead of the normal
* calling sequence, these expect their arguments in registers
* $24 and $25, and return the result in $27. Register $28 may
* be clobbered (assembly temporary), anything else must be saved.
*
* In short: painful.
*
* This is a rather simple bit-at-a-time algorithm: it's very good
* at dividing random 64-bit numbers, but the more usual case where
* the divisor is small is handled better by the DEC algorithm
* using lookup tables. This uses much less memory, though, and is
* nicer on the cache.. Besides, I don't know the copyright status
* of the DEC code.
*/
