     5	// This file contains rules used by flagalloc to split
     6	// a flag-generating merged load op into separate load and op.
     7	// Unlike with the other rules files, not all of these
     8	// rules will be applied to all values.
     9	// Rather, flagalloc will request for rules to be applied
    10	// to a particular problematic value.
    11	// These are often the exact inverse of rules in AMD64.rules,
    12	// only with the conditions removed.
