| 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. |
