Upstream-Status: Pending From 4d4fcfc41288134b48b72ac69702f68741d7631f Mon Sep 17 00:00:00 2001 From: Ting Liu Date: Tue, 28 Jul 2015 16:29:26 +0800 Subject: [PATCH] add -fgnu89-inline option for gcc5 Fix the below build issues: CC drivers/crypto/fsl/sec.o LD arch/powerpc/cpu/mpc8xxx/built-in.o arch/powerpc/cpu/mpc8xxx/fdt.o: In function `ld_le16': ../arch/powerpc/include/asm/byteorder.h:12: multiple definition of `ld_le16' The problem is the change of the default C standard from gnu89 to gnu11 which changes the semantics of 'inline'. The issue is described in the Porting guide at https://gcc.gnu.org/gcc-5/porting_to.html. Adding the '-fgnu89-inline' option fixes the issue.
