            Bug ID: 32493
           Summary: Binutils 2.44 results in unaligned code on
                    linux-sparc64
           Product: binutils
           Version: 2.44 (HEAD)
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: binutils
          Assignee: unassigned at sourceware dot org

                CC: ebotcazou at gcc dot gnu.org, sam at gentoo dot org
  Target Milestone: ---

Building the Linux kernel with binutils 2.43.50.20241221 on linux-sparc64
results with scripts/mod/modpost being built with unaligned access:

/usr/bin/make -f /build/reproducible-path/linux-6.12.6/scripts/Makefile.modpost
# GEN     .vmlinux.objs
  for f in vmlinux.a; do case ${f} in *libgcc.a) ;; *) sparc64-linux-gnu-ar t
${f} ;; esac done > .vmlinux.objs
# MODPOST Module.symvers
   scripts/mod/modpost -M -m       -o Module.symvers -T modules.order vmlinux.o
Bus error

Downgrading binutils 2.43 fixes the problem.
