emit_cmp_insn in alpha

[Hilmi Ozdoganoglu]

when I change the md file and remove the * next to setcc_internal I get
compile errors like this:

any ideas?

... In order to get a compare, you will need to directly call the md
... patterns that emit compare instructions, e.g. setcc_internal.  You will
... need to modify the md file to delete the * so that you can actually call
... these patterns.  Then you do something like
...    emit_insn (gen_setcc_internal (operands...));
...    emit_insn (gen_bcc_normal (operands...));
... It isn't normal to do this sort of thing.  Normally, the epilogue only
... emits move instructions.  Thus there is no easy way to do it.
