From: Dylan Hatch Date: Tue, 23 Sep 2025 00:49:41 +0000 (+0000) Subject: objtool: Fix standalone --hacks=jump_label X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=be8374a5ba7cbab6b97df94b4ffe0b92f5c8a6d2;p=thirdparty%2Fkernel%2Flinux.git objtool: Fix standalone --hacks=jump_label The objtool command line 'objtool --hacks=jump_label foo.o' on its own should be expected to rewrite jump labels to NOPs. This means the add_special_section_alts() code path needs to run when only this option is provided. This is mainly relevant in certain debugging situations, but could potentially also fix kernel builds in which objtool is run with --hacks=jump_label but without --orc, --stackval, --uaccess, or --hacks=noinstr.
