From 070d0094b3f40c61ac041242e1d990e401eb6a22 Mon Sep 17 00:00:00 2001 From: Nick Desaulniers Date: Fri, 5 Feb 2021 12:22:18 -0800 Subject: [PATCH] vmlinux.lds.h: add DWARF v5 sections commit 3c4fa46b30c551b1df2fb1574a684f68bc22067c upstream. We expect toolchains to produce these new debug info sections as part of DWARF v5. Add explicit placements to prevent the linker warnings from --orphan-section=warn. Compilers may produce such sections with explicit -gdwarf-5, or based on the implicit default version of DWARF when -g is used via DEBUG_INFO. This implicit default changes over time, and has changed to DWARF v5 with GCC 11. .debug_sup was mentioned in review, but without compilers producing it today, let's wait to add it until it becomes necessary.
