Bug ID: 32435
Summary: [2.44 Regression] gas produces unaligned sections on
arm-linux-gnueabihf
Product: binutils
Version: 2.44 (HEAD)
Status: NEW
Severity: normal
Priority: P2
Component: gas
Assignee: unassigned at sourceware dot org
Reporter: doko at debian dot org

test case
seen on the trunk, not with 2.43.1 on arm-linux-gnueabihf. The linux build
fails with a bus error during the modpost call. The machine that it is run on
is running an aarch64-linux-gnu kernel.
It looks like the modules are not correctly assembled, resulting in unaligned
file offsets of the sections, attaching here an objdump -h diff for a modules
assemled with gas 2.43.1, and one with gas from the trunk:
$ diff -u pinctrl-cy8c95x0-o.dump pinctrl-cy8c95x0-p.o.dump
