1llvm-lipo - LLVM tool for manipulating universal binaries2=========================================================3 4.. program:: llvm-lipo5 6SYNOPSIS7--------8 9:program:`llvm-lipo` [*filenames...*] [*options*]10 11DESCRIPTION12-----------13: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.14 15COMMANDS16--------17:program:`llvm-lipo` supports the following mutually exclusive commands:18 19.. option:: -help, -h20 21 Display usage information and exit.22 23.. option:: -version24 25 Display the version of this program.26 27.. option:: -verify_arch <architecture 1> [<architecture 2> ...]28 29 Take a single input file and verify the specified architectures are present in the file.30 If so then exit with a status of 0 else exit with a status of 1.31 32.. option:: -archs33 34 Take a single input file and display the architectures present in the file.35 Each architecture is separated by a single whitespace.36 Unknown architectures are displayed as unknown(CPUtype,CPUsubtype).37 38.. option:: -info39 40 Take at least one input file and display the descriptions of each file.41 The descriptions include the filename and architecture types separated by whitespace.42 Universal binaries are grouped together first, followed by thin files.43 Architectures in the fat file: <filename> are: <architectures>44 Non-fat file: <filename> is architecture: <architecture>45 46.. option:: -thin47 48 Take a single universal binary input file and the thin flag followed by an architecture type.49 Require the output flag to be specified, and output a thin binary of the specified architecture.50 51.. option:: -create52 53 Take at least one input file and require the output flag to be specified.54 Output a universal binary combining the input files.55 56.. option:: -replace57 58 Take a single universal binary input file and require the output flag to be specified.59 The replace flag is followed by an architecture type, and a thin input file.60 Output a universal binary with the specified architecture slice in the61 universal binary input replaced with the contents of the thin input file.62 63.. option:: -segalign64 65 Additional flag that can be specified with create and replace.66 The segalign flag is followed by an architecture type, and an alignment.67 The alignment is a hexadecimal number that is a power of 2.68 Output a file in which the slice with the specified architecture has the specified alignment.69 70BUGS71----72 73To report bugs, please visit <https://github.com/llvm/llvm-project/issues/>.74
