From 911455fe1893bcd90d30246117415dfbce658d88 Mon Sep 17 00:00:00 2001 From: Cherry Mui Date: Fri, 12 Sep 2025 12:36:38 -0400 Subject: [PATCH] cmd/link: don't count tbss section in TestFlagD TestFlagD looks for a data-like section at the lowest address. On OpenBSD, the .tbss section matches the current condition, which has address 0, causing the test fail. Don't count TLS sections. Also, print the section name on error. Fixes #75444.
