From: Josh Poimboeuf Date: Mon, 24 Mar 2025 21:56:02 +0000 (-0700) Subject: objtool: Remove --no-unreachable for noinstr-only vmlinux.o runs X-Git-Tag: v6.15-rc1~60^2~24 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=876a4bce3849b235d752d13ec3180e15a35e52de;p=thirdparty%2Flinux.git objtool: Remove --no-unreachable for noinstr-only vmlinux.o runs For (!X86_KERNEL_IBT && !LTO_CLANG && NOINSTR_VALIDATION), objtool runs on both translation units and vmlinux.o. The vmlinux.o run only does noinstr/noret validation. In that case --no-unreachable has no effect. Remove it. Note that for ((X86_KERNEL_IBT || LTO_CLANG) && KCOV), --no-unreachable still gets set in objtool-args-y by scripts/Makefile.lib.
