From 673c2c34f684e9d4328459e426ab54d51a5865c5 Mon Sep 17 00:00:00 2001 From: Chris Metcalf Date: Wed, 8 Jul 2015 17:07:41 -0400 Subject: modpost: work correctly with tile coldtext sections The tilegx and tilepro compilers use .coldtext for their unlikely executed text section name, so an __attribute__((cold)) function will (when compiled with higher optimization levels) land in the .coldtext section. Modify modpost to add .coldtext to the set of OTHER_TEXT_SECTIONS so we don't get warnings about referencing such a section in an __ex_table block, and then also modify arch/tile/lib/memcpy_user_64.c so that it uses plain ".coldtext" instead of ".coldtext.memcpy". The latter naming is a relic of an earlier use of -ffunction-sections, which we no longer use by default.
