From c14560907a9586ad405f26ab937881eb08f39497 Mon Sep 17 00:00:00 2001 From: Filip Kastl Date: Thu, 1 May 2025 15:32:07 +0200 Subject: [PATCH] gimple: Don't warn about using different algs for big switch lowering [PR117091] We currently don't switch to a faster switch lowering algorithm when a switch is too big. This patch removes a warning about this. PR middle-end/117091 gcc/ChangeLog: * tree-switch-conversion.cc (switch_decision_tree::analyze_switch_statement): Remove warning about using different algorithms.
