From ca653464dd097fe64e69f1735e9f348b2a0f8037 Mon Sep 17 00:00:00 2001 From: Josh Poimboeuf Date: Tue, 18 Apr 2023 14:27:48 -0700 Subject: objtool: Add verbose option for disassembling affected functions When a warning is associated with a function, add an option to disassemble that function. This makes it easier for reporters to submit the information needed to diagnose objtool warnings.
