NAME

setarch − change reported architecture in new program environment and set personality flags

SYNOPSIS

setarch arch [options] [program [arguments]]
arch
[options] [program [arguments]]

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. The default program is /bin/sh.

OPTIONS

−v, −−verbose

Be verbose.

−h, −−help

Display help (it is also displayed when setarch takes no arguments).

−3, −−3gb

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

−B, −−32bit

Turns on ADDR_LIMIT_32BIT.

−F, −−fdpic-funcptrs

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

−I, −−short-inode

Turns on SHORT_INODE.

−L, −−addr-compat-layout

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

−R, −−addr-no-randomize

Disables randomization of the virtual address space (turns on ADDR_NO_RANDOMIZE).

−S, −−whole-seconds

Turns on WHOLE_SECONDS.

−T, −−sticky-timeouts

Turns on STICKY_TIMEOUTS.

−X −−read-implies-exec

Turns on READ_IMPLIES_EXEC.

−Z, mmap-page-zero

Turns on MMAP_PAGE_ZERO.

EXAMPLES

setarch ppc32 rpmbuild --target=ppc --rebuild foo.src.rpm
