From 92aa9490315d969d6e7580fb6e8d006415877bd6 Mon Sep 17 00:00:00 2001 From: Richard Biener Date: Tue, 14 Jun 2022 11:10:13 +0200 Subject: [PATCH] tree-optimization/105946 - avoid accessing excess args from uninit diag uninit diagnostics uses passing via reference and access attributes but that iterates over function type arguments which can in some cases appearantly outrun the actual arguments leading to ICEs. The following simply ignores not present arguments. 2022-06-14 Richard Biener PR tree-optimization/105946 * tree-ssa-uninit.cc (maybe_warn_pass_by_reference): Do not look at arguments not specified in the function call.
