From ce776225249d99b089d02424b9472811a6bbd7f5 Mon Sep 17 00:00:00 2001 From: Richard Biener Date: Tue, 30 Aug 2022 14:37:23 +0200 Subject: [PATCH] tree-optimization/73550 - apply MAX_NUM_CHAINS consistently The MAX_NUM_CHAINS is applied once with <= and once with < which results in the chains not limited but analyis dropped completely.
