I guess we need to add something like #if !CONFIG_CC_IS_GCC || CONFIG_LD_VERSION >= 23600 around the entry-armv.S changes and maybe select HAVE_LD_DEAD_CODE_DATA_ELIMINATION in arch/arm/Kconfig only if the same conditions are met ?? I had screwed up the CC list when I last replied and LAK list got changed to lak-join email id by mistake. Fixing that in this reply as well. Thanks, Warm Regards, Harith
