SYM_FUNC_START_LOCAL_NOALIGN() adds an endbr leading to this layout (leaving only the last 2 bytes of the address): 3bff <zen_untrain_ret>: 3bff: f3 0f 1e fa endbr64 3c03: f6 test $0xcc,%bl 3c04 <__x86_return_thunk>: 3c04: c3 ret 3c05: cc int3 3c06: 0f ae e8 lfence However, "the RET at __x86_return_thunk must be on a 64 byte boundary, for alignment within the BTB." Use SYM_START instead.
