NAME
       setarch	- change reported architecture in new program environment and
       set personality 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.

       -I     Turns on SHORT_INODE.

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

       -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
