From 895fb3159280fe7695b35ec7c87ec19e13ca5b6e Mon Sep 17 00:00:00 2001 From: Max Filippov Date: Fri, 21 Aug 2015 20:43:44 +0300 Subject: xtensa: improve vmlinux.lds.S sed post-processing Current sed script makes assumptions about the structure of rules that group .text sections in the vmlinux linker script. These assumptions get broken occasionally, e.g.: 779c88c94c34 "ARM: 8321/1: asm-generic: introduce.text.fixup input section", or 9bebe9e5b0f3 "kbuild: Fix .text.unlikely placement". Rewrite sed rules so that they don't depend on number/arrangement of text sections in *(...) blocks.
