It needs "ld -r" and "ld -e 0", and takes a fraction ofa second.The fixture places the static appearing first in the symbol table at thehigher address, and the link passes --sort-section=name to force thereordering the kernel's linker script performs. Without that the two waysof computing sympos agree, and a first version passed with the vmlinux pathdisabled.Assisted-by: Claude:claude-opus-4Based-on-test-by: Joe Lawrence <joe.lawrence@redhat.com>Assisted-by: Claude:claude-opus-5Signed-off-by: Song Liu <song@kernel.org>Signed-off-by: Josh Poimboeuf <jpoimboe@kernel.org>Signed-off-by: Ingo Molnar <mingo@kernel.org>Link: https://patch.msgid.link/20260916184351.2720310-39-song@kernel.org List of files: /linux/tools/objtool/tests/generic/test-sympos-vmlinux.sh Wed, 16 Sep 2026 20:43:31 +0200 Song Liu <song@kernel.org>
