This core generates an LR(1) parser from a context free grammar. It applies the IELR(1) algorithm as described in the paper "The IELR(1) algorithm for generating minimal LR(1) parser tables for non-LR(1) grammars with conflict resolution" by Joel E. Denny and Brian A. Malloy.
This is an alias for IELR(1) GoLR.
