The arch_kgdb_breakpoint() function defines the kgdb_compiled_break symbol using inline assembly. There's a potential issue where the compiler might inline arch_kgdb_breakpoint(), which would then define the kgdb_compiled_break symbol multiple times, leading to fail to link vmlinux.o. This isn't merely a potential compilation problem. The intent here is to determine the global symbol address of kgdb_compiled_break, and if this function is inlined multiple times, it would logically be a grave error. 2. Remove ".option norvc/.option rvc" to fix a bug that the C extension would unconditionally enable even if the kernel is being built with CONFIG_RISCV_ISA_C=n. * b4-shazam-merge: riscv: KGDB: Remove ".option norvc/.option rvc" for kgdb_compiled_break riscv: KGDB: Do not inline arch_kgdb_breakpoint() Link: https://lore.kernel.org/r/D5A83DF3A06E1DF9+20250411072905.55134-1-wangyuli@uniontech.com Signed-off-by: Palmer Dabbelt --- dc3e30b4992336007c9798e5785b47819c7ef58e
