	* sysdeps/alpha, sysdeps/unix/bsd/osf/alpha,
	sysdeps/unix/bsd/Attic/osf1/alpha, sysdeps/unix/sysv/linux/alpha,
	sysdeps/unix/sysv/linux/alpha/alpha, sysdeps/unix/alpha,
	sysdeps/mach/alpha, sysdeps/mach/hurd/alpha:
	Subdirectories moved to ports repository.
	* configure.in (base_machine): Remove alpha case.

-/* 64-bit unsigned long divide.  These are not normal C functions.  Argument
-   registers are t10 and t11, the result goes in t12.  Only t12 and AT may be
-   clobbered.
-
-   Theory of operation here is that we can use the FPU divider for virtually
-   all operands that we see: all dividend values between -2**53 and 2**53-1
-   can be computed directly.  Note that divisor values need not be checked
-   against that range because the rounded fp value will be close enough such
-   that the quotient is < 1, which will properly be truncated to zero when we
-   convert back to integer.
-
-   When the dividend is outside the range for which we can compute exact
-   results, we use the fp quotent as an estimate from which we begin refining
-   an exact integral value.  This reduces the number of iterations in the
-   shift-and-subtract loop significantly.
-
-   The FPCR save/restore is due to the fact that the EV6 _will_ set FPCR_INE
-   for cvttq/c even without /sui being set.  It will not, however, properly
-   raise the exception, so we don't have to worry about FPCR_INED being clear
-   and so dying by SIGFPE.  */
