[U-Boot] GCC5.x support for old u-boot version
Hello,
we have an am335x based custom board that use for our Project. At the moment only a customized version of uboot-2013.01.01 supports this board. As we use Yocto toolchains and we plan to upgrade to latest Yocto-2.0 that comes with GCC5.2.
I would like to be able to build this custom old version with newer toolchains.
For that I added from new u-boot the file : include/linux/compiler-gcc5.h
But still having some compile errors :
| arm-poky-linux-gnueabi-gcc --sysroot=/yocto/build/tmp/sysroots/shc -g -Os -fno-common -ffixed-r8 -msoft-float -D__KERNEL__ -DCONFIG_SYS_TEXT_BASE=0x80800000 -DCONFIG_SPL_TEXT_BASE=0x402F0400 -I/yocto/build/tmp/work/shc-poky-linux-gnueabi/u-boot-shc/1.0-r1/git/include -fno-builtin -ffreestanding -nostdinc -isystem /yocto/build/tmp/sysroots/x86_64-linux/usr/lib/arm-poky-linux-gnueabi/gcc/arm-poky-linux-gnueabi/5.2.0/include -pipe -DCONFIG_ARM -D__ARM__ -marm -mno-thumb-interwork -mabi=aapcs-linux -march=armv7-a -mcpu=cortex-a8 -Wall -Wstrict-prototypes -fno-stack-protector -Wno-format-nonliteral -Wno-format-security -fstack-usage -o s_record.o s_record.c -c | main.c:62:6: error: 'show_boot_progress' aliased to external symbol '__show_boot_progress' | void show_boot_progress (int val) __attribute__((weak, alias("__show_boot_progress"))); | ^ | make[1]: *** [main.o] Error 1 | make[1]: Leaving directory `/yocto/build/tmp/work/shc-poky-linux-gnueabi/u-boot/1.0-r1/git/common' | make: *** [common/libcommon.o] Error 2
Any chance to backport GCC5 support to old u-boot version ?
Thank you for suggestions.
Best regards,

Perhaps this helps "inline: use the gcc inline version instead of the c99 one." http://lists.denx.de/pipermail/u-boot/2014-May/180709.html
