+Subject: [PATCH] avoid calling printf because OE glibc-2.34 used
+ -mno-outline-atomics buildflag, it will cause printf to be non-atomic
+ operations on ARMv8.1 platform. This will cause printf to stuck into dead
+ loop because ptrace sing-step execution cause race condition during printf
+ instructions.

+ unw_get_proc_info() return unsuccessful result. Because it is not an error
+ unw_get_proc_info() does not return the auxiliary information, so we edit
