[PATCH] avoid recomputing PHI results after failure (PR 104203)

2022-01-24 Thread Martin Sebor via Gcc-patches
The pointer_query algorithm fails when it's unable to determine the provenance of an pointer SSA variable. A failure prevents it from making a record of the variable in the cache. Although this doesn't happen often, one common cause of failures is PHI nodes: e.g., because one of its arguments re
