From e229f9b8f5d060056883ddb379b191c451e20139 Mon Sep 17 00:00:00 2001 From: Richard Biener Date: Fri, 29 Apr 2022 11:54:45 +0200 Subject: [PATCH] tree-optimization/105394 - vector lowering of compares The following fixes missing handling of non-integer mode but masked (SVE or MVE) compares in vector lowering by using the appropriate mask element width to extract the components and adjust the index. 2022-04-29 Richard Biener PR tree-optimization/105394 * tree-vect-generic.cc (expand_vector_condition): Adjust comp_width for non-integer mode masks as well.
