Now I use latest tool-chain (content gcc-4.8.0) to compile kernel with allmodconfig, and find three tool chain issues (2 for gcc, 1 for binutils). And also excuse me, I am still not quite sure where I should sent these information to, although you have mentioned some valuable information. I just list the issue details below, if necessary, please provide more details where these information should be sent to (e.g. bugzilla), and I will/should follow and work with related tool chain guys. thanks. -------------------------information begin---------------------------- Operation: for Linux next-20130927 tree make ARCH=arc CROSS_COMPILE=/usr/local/bin/arc-elf32- allmodconfig make ARCH=arc CROSS_COMPILE=/usr/local/bin/arc-elf32- Binutils (1 issue, ld and as information): when calling panic(), printk(), or memset() with R_ARC_S21W_PCREL, it may be overflow (I guess it need be R_ARC_S25W_PCREL). /usr/local/bin/arc-elf32-ld --build-id -X -o .tmp_vmlinux1 -T /android/public-kernel/linux-next/arch/arc/kernel/vmlinux.lds arch/arc/kernel/head.o init/built-in.o --start-group usr/built-in.o arch/arc/built-in.o arch/arc/boot/dts/built-in.o arch/arc/plat-arcfpga/built-in.o arch/arc/plat-tb10x/built-in.o kernel/built-in.o mm/built-in.o fs/built-in.o ipc/built-in.o security/built-in.o crypto/built-in.o block/built-in.o lib/lib.a arch/arc/lib/lib.a /usr/local/lib/gcc/arc-elf32/4.8.0/libgcc.a lib/built-in.o arch/arc/lib/built-in.o /usr/local/lib/gcc/arc-elf32/4.8.0/libgcc.a drivers/built-in.o sound/built-in.o firmware/built-in.o net/built-in.o --end-group /usr/local/bin/arc-elf32-ld: Error: Overflow detected in relocation value; /usr/local/bin/arc-elf32-ld: Relocation value should be between 1048575 and -1048576 whereas it 2404264 /usr/local/bin/arc-elf32-ld: Global symbol: "panic". /usr/local/bin/arc-elf32-ld: Relocation type is:R_ARC_S21W_PCREL FileName:arch/arc/built-in.o Section Name:.text Offset in Section:1716 /usr/local/bin/arc-elf32-ld: final link failed: Bad value make: *** [vmlinux] Error 1 [root@gchenlinux binutils]# arc-elf32-ld -v GNU ld (GNU Binutils) 2.23.2 [root@gchenlinux binutils]# arc-elf32-as -v GNU assembler version 2.23.2 (arc-elf32) using BFD version (GNU Binutils) 2.23.2 GCC (2 issues, and gcc information): CC drivers/rtc/systohc.o drivers/rtc/systohc.c: In function 'rtc_set_ntp_time': drivers/rtc/systohc.c:44:1: internal compiler error: in arc_ifcvt, at config/arc/arc.c:8315 } ^ 0x939c94 arc_ifcvt ../../gcc/gcc/config/arc/arc.c:8315 0x93a394 arc_reorg ../../gcc/gcc/config/arc/arc.c:5985 0x7517d9 rest_of_handle_machine_reorg ../../gcc/gcc/reorg.c:3927 Please submit a full bug report, with preprocessed source if appropriate.
