| struct chain* chain::ch1 |
| struct chain * chain::ch2 |
| unsigned chain::combined |
True if this chain was combined together with some other chain.
Referenced by replace_names_by_phis().
| unsigned chain::has_max_use_after |
True if there is a use of a variable with the maximal distance that comes after the root in the loop.
Referenced by find_looparound_phi().
| unsigned chain::length |
The maximum distance of the reference in the chain from the root.
