rebase(1) BSD General Commands Manual rebase(1)
NAME
rebase -- Changes base address of dylibs and bundles
SYNOPSIS
rebase [-low_address addr] [-high_address addr] [-arch arch] [-v] file(s)
DESCRIPTION
The base address of an image (dylib or bundle) is the preferred address
for it to be loaded. By default all images are built with a base address
of zero. At runtime, if the preferred memory range is already occupied,
dyld will "slide" the image to a new address range. There is a small
cost to the slide, as dyld must do some fix ups. The rebase tool takes a
list of images and adjust their base address to be non-overlapping. If no
low or high address is specified, the a suitable address range is choosen
for the architecture.
The options are as follows:
-low_address addr
Force the base address for the first image to be addr (specified
in hex). Each subsequent file gets the next available base
address.
-high_address addr
Force the base address for the last image to be such that when
that image is loaded it occupies memory up to addr (specified in
hex). Each preceeding file gets the previous available base
address.
-arch arch
Only rebase the specified architecture. Other architectures in a
universal image are left as is.
-v Verbose. Print information about rebasing done.
