From 27f2a4db76e8d8a8b601fc1c6a7a17f88bd907ab Mon Sep 17 00:00:00 2001 From: Nick Desaulniers Date: Fri, 21 May 2021 18:26:24 -0700 Subject: Makefile: fix GDB warning with CONFIG_RELR GDB produces the following warning when debugging kernels built with CONFIG_RELR: BFD: /android0/linux-next/vmlinux: unknown type [0x13] section `.relr.dyn' when loading a kernel built with CONFIG_RELR into GDB. It can also prevent debugging symbols using such relocations. Peter sugguests: [That flag] means that lld will use dynamic tags and section type numbers in the OS-specific range rather than the generic range. The kernel itself doesn't care about these numbers; it determines the location of the RELR section using symbols defined by a linker script.
