Serge Rielau updated SPARK-50319:
---------------------------------
Description:
The current relative order of rules is:
# ResolveRelations
# ResolveIdentifierClause
# BindParameters
These rules interact in exactly the opposite way as they are listed:
* BindParameters always operates on leafs
* ResolveIdentifierClause turns constant expressions (typically parameters)
into UnresolvedRelations
* ResolveRelations is needed to progress resolved identifier clauses
We propose to move BindParameters and ResolveIdentifierClause up.
was:BindParameters
> Reorder BindParameters and ResolveIdentifierClause rules to converge to
> fixpoint faster
