There is no compat support in strace and there are no systems within reach that would allow to test it. * linux/ia64/arch_regs.c (IA64_PSR_IS, ia64_ia32mode): Remove. * linux/ia64/get_error.c (get_error): Remove ia64_ia32mode branch. * linux/ia64/get_scno.c (arch_get_scno): Likewise. * linux/ia64/get_syscall_args.c (get_syscall_args): Likewise. * linux/ia64/set_error.c (arch_set_error, arch_set_success): Likewise. * linux/ia64/set_scno.c (arch_set_scno): Likewise.
