llvm-lipo - LLVM tool for manipulating universal binaries
|
|
=========================================================
|
|
|
|
.. program:: llvm-lipo
|
|
|
|
SYNOPSIS
|
|
--------
|
|
|
|
:program:`llvm-lipo` [*filenames...*] [*options*]
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
:program:`llvm-lipo` can create universal binaries from Mach-O files, extract regular object files from universal binaries, and display architecture information about both universal and regular files.
|
|
|
|
COMMANDS
|
|
--------
|
|
:program:`llvm-lipo` supports the following mutually exclusive commands:
|
|
|
|
.. option:: -help, -h
|
|
|
|
Display usage information and exit.
|
|
|
|
.. option:: -version
|
|
|
|
Display the version of this program.
|
|
|
|
.. option:: -verify_arch <architecture 1> [<architecture 2> ...]
|
|
|
|
Take a single input file and verify the specified architectures are present in the file.
|
|
If so then exit with a status of 0 else exit with a status of 1.
|
|
|
|
.. option:: -archs
|
|
|
|
Take a single input file and display the architectures present in the file.
|
|
Each architecture is separated by a single whitespace.
|
|
Unknown architectures are displayed as unknown(CPUtype,CPUsubtype).
|
|
|
|
.. option:: -info
|
|
|
|
Take at least one input file and display the descriptions of each file.
|
|
The descriptions include the filename and architecture types separated by whitespace.
|
|
Universal binaries are grouped together first, followed by thin files.
|
|
Architectures in the fat file: <filename> are: <architectures>
|
|
Non-fat file: <filename> is architecture: <architecture>
|
|
|
|
.. option:: -thin
|
|
|
|
Take a single universal binary input file and the thin flag followed by an architecture type.
|
|
Require the output flag to be specified, and output a thin binary of the specified architecture.
|
|
|
|
.. option:: -create
|
|
|
|
Take at least one input file and require the output flag to be specified.
|
|
Output a universal binary combining the input files.
|
|
|
|
.. option:: -replace
|
|
|
|
Take a single universal binary input file and require the output flag to be specified.
|
|
The replace flag is followed by an architecture type, and a thin input file.
|
|
Output a universal binary with the specified architecture slice in the
|
|
universal binary input replaced with the contents of the thin input file.
|
|
|
|
.. option:: -segalign
|
|
|
|
Additional flag that can be specified with create and replace.
|
|
The segalign flag is followed by an architecture type, and an alignment.
|
|
The alignment is a hexadecimal number that is a power of 2.
|
|
Output a file in which the slice with the specified architecture has the specified alignment.
