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.
