-Subject: [PATCH] ipa-fnsummary: Fix ICE with switch predicates [PR96130]
-
-The following testcase ICEs since r10-3199.
-There is a switch with default label, where the controlling expression has
-range just 0..7 and there are case labels for all those 8 values, but
-nothing has yet optimized away the default.
-Since r10-3199, set_switch_stmt_execution_predicate sets the switch to
-default label's edge's predicate to a false predicate and then
-compute_bb_predicates propagates the predicates through the cfg, but false
-predicates aren't really added.  The caller of compute_bb_predicates
-in one place handles NULL bb->aux as false predicate:
-      if (fbi.info)
-	{
-	  if (bb->aux)
-	    bb_predicate = *(predicate *) bb->aux;
-	  else
-	    bb_predicate = false;
-	}
-      else
-	bb_predicate = true;
-but then in two further spots that the patch below is changing
-it assumes bb->aux must be non-NULL.  Those two spots are guarded by a
-condition that is only true if fbi.info is non-NULL, so I think the right
-fix is to treat NULL aux as false predicate in those spots too.
