I'm getting the following bootstrap failure on mainline with current CVS:

This seems to have been introduced in the last one or two weeks.

Caused by:
2005-03-13  David Edelsohn  <edelsohn@gnu.org>
        
        * config/rs6000/predicates.md (mem_or_easy_const_operand): Delete.
        (reg_or_none500mem_operand): New predicate.
        (zero_reg_mem_operand): New predicate.
        * config/rs6000/rs6000.md (extendsfdf2): Change operand1 predicate
        to reg_or_none500mem_operand.
        (extendsfdf2_fpr): Add MEM alternative.
        (extenddftf2_internal): Change operand2 predicate to
        zero_reg_mem_operand.


I will try to fix this, it might just need REG_P (operands[1]) in the split criteria.
