Message-ID: <05414246a0124db2f21b0d071b652aa9043d039d.1742852847.git.jpoimboe@kernel.org> Date: Mon, 24 Mar 2025 14:56:02 -0700 From: Josh Poimboeuf <jpoimboe@...nel.org> To: x86@...nel.org Cc: linux-kernel@...r.kernel.org, Peter Zijlstra <peterz@...radead.org>, Ingo Molnar <mingo@...nel.org>, Miroslav Benes <mbenes@...e.cz>, Brendan Jackman <jackmanb@...gle.com>, Nathan Chancellor <nathan@...nel.org> Subject: [PATCH 12/22] 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.
