Entries with ANNOTATE_DATA_SPECIAL arehandled first; the rest have their boundaries derived from the entry orrelocation size.The second pass has to key off whether the first one created symbols, notoff whether the section already has something at offset 0. Clang puts anassembler-local label at the start of .kcfi_traps, and treating that asalready handled means nothing is extracted: klp diff still reports thechanged function and succeeds, but the special section is missing from themodule.The fixture reproduces the shape without needing CFI or x86.Signed-off-by: Puranjay Mohan <puranjay@kernel.org>Signed-off-by: Song Liu <song@kernel.org>Signed-off-by: Josh Poimboeuf <jpoimboe@kernel.org>Signed-off-by: Ingo Molnar <mingo@kernel.org>Assisted-by: Claude:claude-opus-5Link: https://patch.msgid.link/20260916184351.2720310-18-song@kernel.org List of files: /linux/tools/objtool/tests/generic/test-special-section.sh Wed, 16 Sep 2026 20:43:10 +0200 Puranjay Mohan <puranjay@kernel.org>
