+== NAME
+
+setarch - change reported architecture in new program environment and/or set personality flags
+
+== SYNOPSIS
+
+*setarch* [_arch_] [options] [_program_ [_argument_...]]
+
+*setarch* *--list*|*-h*|*-V*
+
+*arch* [options] [_program_ [_argument_...]]
+
+== DESCRIPTION
+
+*setarch* modifies execution domains and process personality flags.
+
+The execution domains currently only affects the output of *uname -m*. For example, on an AMD64 system, running *setarch i386* _program_ will cause _program_ to see i686 instead of _x86_64_ as the machine type. It can also be used to set various personality options. The default _program_ is */bin/sh*.
+
+Since version 2.33 the _arch_ command line argument is optional and *setarch* may be used to change personality flags (ADDR_LIMIT_*, SHORT_INODE, etc) without modification of the execution domain.
+
+== OPTIONS
+
+*--list*::
+List the architectures that *setarch* knows about. Whether *setarch* can actually set each of these architectures depends on the running kernel.
+
+*--show[=personality]*::
+Show the currently active personality and flags.
+If the *personality* argument is provided, it is shown instead of the current one.
+*personality* is a hexadecimal number with values was described in *sys/personality.h*.
+
+*--uname-2.6*::
+Causes the _program_ to see a kernel version number beginning with 2.6. Turns on *UNAME26*.
+
+*-v*, *--verbose*::
+Be verbose.
+
+*-3*, *--3gb*::
+Specifies _program_ should use a maximum of 3GB of address space. Supported on x86. Turns on *ADDR_LIMIT_3GB*.
+
+*--4gb*::
+This option has no effect. It is retained for backward compatibility only, and may be removed in future releases.
+
+*-B*, *--32bit*::
+Limit the address space to 32 bits to emulate hardware. Supported on ARM and Alpha. Turns on *ADDR_LIMIT_32BIT*.
+
+*-F*, *--fdpic-funcptrs*::
+Treat user-space function pointers to signal handlers as pointers to address descriptors. This option has no effect on architectures that do not support *FDPIC* ELF binaries. In kernel v4.14 support is limited to ARM, Blackfin, Fujitsu FR-V, and SuperH CPU architectures.
+
+*-I*, *--short-inode*::
+Obsolete bug emulation flag. Turns on *SHORT_INODE*.
+
+*-L*, *--addr-compat-layout*::
+Provide legacy virtual address space layout. Use when the _program_ binary does not have *PT_GNU_STACK* ELF header. Turns on *ADDR_COMPAT_LAYOUT*.
+
+*-R*, *--addr-no-randomize*::
+Disables randomization of the virtual address space. Turns on *ADDR_NO_RANDOMIZE*.
+
+*-S*, *--whole-seconds*::
+Obsolete bug emulation flag. Turns on *WHOLE_SECONDS*.
+
+*-T*, *--sticky-timeouts*::
+This makes *select*(2), *pselect*(2), and *ppoll*(2) system calls preserve the timeout value instead of modifying it to reflect the amount of time not slept when interrupted by a signal handler. Use when _program_ depends on this behavior. For more details see the timeout description in *select*(2) manual page. Turns on *STICKY_TIMEOUTS*.
+
+*-X*, *--read-implies-exec*::
+If this is set then *mmap*(2) *PROT_READ* will also add the *PROT_EXEC* bit - as expected by legacy x86 binaries. Notice that the ELF loader will automatically set this bit when it encounters a legacy binary. Turns on *READ_IMPLIES_EXEC*.
+
+*-Z*, *--mmap-page-zero*::
+SVr4 bug emulation that will set *mmap*(2) page zero as read-only. Use when _program_ depends on this behavior, and the source code is not available to be fixed. Turns on *MMAP_PAGE_ZERO*.
