Changed paths:
   M /trunk/gcc/ChangeLog
   M /trunk/gcc/config/alpha/alpha.md

alpha: Cleanup sign extension patterns.

Don't bother implementing sub-word sign-extensions for !BWX,
since we need to use DImode intermediates anyway.

   M /trunk/gcc/config/alpha/alpha.md
   M /trunk/gcc/config/alpha/constraints.md

alpha: Unify SF, DF, QI, HI, SI mode moves with enabled attribute.

For floating-point, this involves in addition conditionalizing the
definition of the "f" register constraint.
