NAME

       llvm-lipo - LLVM tool for manipulating universal binaries

SYNOPSIS

       llvm-lipo [filenames…] [options]

DESCRIPTION

       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

       llvm-lipo supports the following mutually exclusive commands:

       -help, -h
              Display usage information and exit.

       -version
              Display the version of this program.

       -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.

       -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).

       -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>

       -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.

       -create
              Take at least one input file and require the output flag to be specified.  Output a
              universal binary combining the input files.

       -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.

       -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.
