After commit 9cc1df421f00 ("LoongArch: Update Loongson-3 default config file"), there exist some build regressions about objtool warnings on LoongArch. This is because objtool does not work well with jump tables, -fno-jump-tables is already added in Makefile, but there are some special cases, some warnings can be reproduced because the code has __annotate_jump_table, some warnings can not be reproduced with unknown reason (maybe due to the lower version of compiler toolchain). In order to avoid the warnings reported by kernel test robot, it is better to remove CONFIG_UNWINDER_ORC=y in defconfig for now, the proper time to enable ORC stack unwinder should after objtool supports jump tables on LoongArch. arch/loongarch/Makefile ifdef CONFIG_OBJTOOL KBUILD_CFLAGS += -fno-jump-tables endif include/linux/compiler.h /* Annotate a C jump table to allow objtool to follow the code flow */ #define __annotate_jump_table __section(".rodata..c_jump_table") Like this: diff --git a/arch/loongarch/configs/loongson3_defconfig b/arch/loongarch/configs/loongson3_defconfig index b4252c357c8e..0eb14e9259c2 100644 --- a/arch/loongarch/configs/loongson3_defconfig +++ b/arch/loongarch/configs/loongson3_defconfig @@ -983,4 +983,3 @@ CONFIG_DEBUG_FS=y CONFIG_SCHEDSTATS=y # CONFIG_DEBUG_PREEMPT is not set # CONFIG_FTRACE is not set -CONFIG_UNWINDER_ORC=y Thanks, Tiezhu ^ permalink raw reply related [flat|nested] 9+ messages in thread
