Garret Rieger 1405f96b6f [repacker] change run_resolve_overflow_test to check for graph equivalence. 
Replaces a check for an exact match on the final serialized bytes. The previous check enforced equivalent topological sorting between result and expected, but we only really care that the graph's are equivalent and don't overflow.
 2022-08-15 23:48:00 +00:00
Garret Rieger 07fd0528c0 [repacker] add graph equality check. 
Does not compare topological sorting, but looks for equivalence of the two graphs.

Garret Rieger 5d824c09c0 [repacker] during table splits don't mutate shared coverage/classdef in place. 
If other subtables are sharing coverage with a subtable being split we have to duplicate the coverage/classdef tables before they are modified during the shrink operation.

Garret Rieger 60d6ffb375 [repacker] always duplicate classDef2 when splitting a PairPos2. 
Splits are done in a way that it shouldn't be possible to share the classDef2 between split PairPos2's so pre-emptively duplicate it.
