.SH NAME
codesign_allocate \-  add code signing data to a Mach-O file
.SH SYNOPSIS
.B codesign_allocate
\-i oldfile [ \-a arch size ]... [ \-A cputype cpusubtype size ]... \-o newfile
.SH DESCRIPTION
.I codesign_allocate
sets up a Mach-O file used by the dynamic linker so space for code signing data
of the specified size for the specified architecture is embedded in the Mach-O
file.  The program must be passed one \-a argument or one \-A argument for each
architecture in a universal file, or exactly one \-a or \-A for a thin file.
.TP
.BI \-i " oldfile"
specifies the input file as
.I oldfile.
.TP
.BI \-o " newfile"
specifies the output file as
.I newfile.
.TP
.BI \-a " arch size"
specifies for the architecture
.I arch
that the size of the code signing data is to be
.I size.
The value of
.I size
must be a multiple of 16.
.TP
.BI \-A " cputype cpusubtype size"
specifies for the architecture as a pair of decimal integers for the cputype and
cpusubtype that the size of the code signing data is to be
.I size.
The value of
.I size
must be a multiple of 16.
.TP
.BI \-r
remove the code signature data and the LC_CODE_SIGNATURE load command.  This
is the same as specifiying the
.B -a
or
.B -A
option with a
.I size
of zero.
.TP
.BI \-p
page align the code signature data by padding string table and changing its
size.  This is not the default as
.IR codesign (1)
currently can't use this option.
