Field Documentation
| char occr::copied_p |
Nonzero if this [available] occurrence has been copied to
reaching_reg. ??? This is mutually exclusive with deleted_p, so they could share
the same byte.

| char occr::deleted_p |
Nonzero if this [anticipatable] occurrence has been deleted.

| rtx occr::insn |
The insn that computes the expression.
