Bug ID: 20519
Summary: "PowerPC64, Don't copy weak symbol dyn_relocs to
weakdef." causes abort at elf64-ppc.c:14898
Product: binutils
Version: 2.28 (HEAD)
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: ld
Assignee: unassigned at sourceware dot org
Reporter: npiggin at gmail dot com
CC: amodra at gmail dot com
Target Milestone: ---
Host: powerpc64le-unknown-linux-gnu
Target: powerpc64le-unknown-linux-gnu
With a powerpc64le allyesconfig build of the Linux kernel, using thin archives
and --gc-sections, I see ld failing:
npiggin@p84-npiggin:~/src/linux$ time ../binutils/binutils-gdb/ld/ld-new -EL -m
elf64lppc -pie --emit-relocs --build-id --gc-sections -X -o vmlinux -T
./arch/powerpc/kernel/vmlinux.lds --whole-archive built-in.o .tmp_kallsyms3.o
../binutils/binutils-gdb/ld/ld-new: BFD (GNU Binutils) 2.27.51.20160819
internal error, aborting at elf64-ppc.c:14898 in ppc64_elf_relocate_section
Bisected to d311bc8bf85f8358df21301fe8a357aa1212f80c
This build requires some out of tree patches to the kernel, so I can test
patches and report back, or for IBMers I can give a login to my VM if that
would help.
