By very popular demand. While we are here, let's refactor the condition for old_mmap_pgoff into an arch-specific one, as it is used more than in one place. * NEWS: Mention this. * strace.1.in (.SH "MULTIPLE PERSONALITY SUPPORT"): Likewise. * configure.ac (case "$host_cpu" in) <s390x>: Set arch_m32 to s390, set cc_flags_m32 to -m31. (st_MPERS([m32])): Add s390x. * defs.h [S390X]: Define NEED_UID16_PARSERS. * linux/s390/arch_sigreturn.c [!S390_FRAME_PTR] (S390_FRAME_PTR): New macro, define to s390_frame_ptr. [!SIGNAL_FRAMESIZE] (SIGNAL_FRAMESIZE): New macro, define to __SIGNAL_FRAMESIZE. [!PTR_TYPE] (PTR_TYPE): New macro, define to unsigned long. (arch_sigreturn): Use S390_FRAME_PTR, SIGNAL_FRAMESIZE, and PTR_TYPE instead of s390_frame_ptr, __SIGNAL_FRAMESIZE, and pointer-sized type, respectively. * linux/s390/get_error.c [!ARCH_REGSET] (ARCH_REGSET): New macro, define * to s390_regset. (get_error): Use it instead of s390_regset. * linux/s390/get_scno.c (arch_get_scno): Likewise. * linux/s390/get_syscall_args.c (get_syscall_args): Likewise. * linux/s390/set_error.c (arch_set_error, arch_set_success): Likewise. * linux/s390/set_scno.c (arch_set_scno): Likewise. * linux/s390x/arch_regs.c (psw_compat_t, s390_compat_regs, s390x_regs_union, s390_frame_ptr, s390x_frame_ptr, s390x_io): New variables. (s390_regset, s390x_regset, ARCH_REGS_FOR_GETREGSET, ARCH_IOVEC_FOR_GETREGSET, ARCH_PC_REG, ARCH_PERSONALITY_0_IOV_SIZE, ARCH_PERSONALITY_1_IOV_SIZE): New macros. * linux/s390x/arch_regs.h (s390_frame_ptr, s390x_frame_ptr): New prototypes. * linux/s390x/arch_rt_sigframe.c: Conditionalize on tcp->currpers. * linux/s390x/arch_sigreturn.c: Likewise. * linux/s390x/get_error.c: Likewise. * linux/s390x/get_scno.c: Likewise. * linux/s390x/get_syscall_args.c: Likewise. * linux/s390x/set_error.c: Likewise. * linux/s390x/set_scno.c: Likewise. * linux/s390x/errnoent1.h: New file. * linux/s390x/ioctls_arch1.h: Likewise. * linux/s390x/ioctls_inc1.h: Likewise. * linux/s390x/signalent1.h: Likewise. * linux/s390x/syscallent1.h: Likewise. * Makefile.am (EXTRA_DIST): Add new files added to linux/s390x. * supported_personalities.h [S390X] (SUPPORTED_PERSONALITIES): Define to 2. * tests/strace-V.test: Add s390 to the list of architectures that have m32 personality. * linux/s390/arch_defs.h (HAVE_ARCH_OLD_MMAP_PGOFF): New macro. * linux/s390x/arch_defs.h: Likewise. * mem.c: Replace #ifdef S390 with #ifdef HAVE_ARCH_OLD_MMAP_PGOFF. * pathtrace.c: Likewise.
