SETARCH(8)                 Linux Programmer’s Manual                SETARCH(8)



NAME
       setarch - change reported architecture in new program environment and set personal-
       ity flags

SYNOPSIS
       setarch arch [options] program

       arch [options] program


DESCRIPTION
       setarch This utility currently only affects the output of uname -m. For example, on
       an  AMD64  system,  running ’setarch i386 program’ will cause ’program’ to see i686
       (or other relevant arch) instead of x86_64 as machine type. It also allows  to  set
       various personality options.

OPTIONS
       -v     Be verbose.

       -3     Specifies  that  processes  should  use a maximum of 3GB of address space on
              systems where it is supported (ADDR_LIMIT_3GB).

       -B     Turns on ADDR_LIMIT_32BIT.

       -F     Userspace function pointers point to descriptors (turns on  FDPIC_FUNCPTRS).

       -I     Turns on SHORT_INODE.

       -L     Changes  the  way virtual memory is allocated (turns on the ADDR_COMPAT_LAY-
              OUT).

       -R     Disables randomization of the virtual address space (turns  on  ADDR_NO_RAN-
              DOMIZE).

       -S     Turns on WHOLE_SECONDS.

       -T     Turns on STICKY_TIMEOUTS.

       -X     Turns on READ_IMPLIES_EXEC.

       -Z     Turns on MMAP_PAGE_ZERO.

EXAMPLES
       setarch ppc32 rpmbuild --target=ppc --rebuild foo.src.rpm
       setarch ppc32 -v -vL3 rpmbuild --target=ppc --rebuild bar.src.rpm
