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
Reporter: glaubitz at physik dot fu-berlin.de
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.
