From 3ebd1cbc49f0005092d69cf0d9a6e64d7a1c300b Mon Sep 17 00:00:00 2001 From: Albert ARIBAUD Date: Mon, 25 Feb 2013 00:58:59 +0000 Subject: arm: make __bss_start and __bss_end__ compiler-generated Turn __bss_start and __bss_end__ from linker-generated to compiler-generated symbols, causing relocations for these symbols to change type, from R_ARM_ABS32 to R_ARM_RELATIVE. This should have no functional impact, as it affects references to __bss_start and __bss_end__ only before relocation, and no such references are done.

This causes relocation records of type R_ARM_ABS32 to become R_ARM_RELATIVE, which makes code which uses LGA able to run before relocation as well as after. Note: this affects more than ARM targets, as linker- lists span possibly all target architectures, notably PowerPC.
