GENCCODE(8)                                ICU 70.1 Manual                               GENCCODE(8)



NAME
       genccode - generate C or platform specific assembly code from an ICU data file.

SYNOPSIS
       genccode  [  -h,  -?,  --help  ]  [ -a, --assembly name ] [ -d, --destdir destination ] [ -n,
       --name name ] [ -e, --entrypoint name ] [ -f, --filename name ] [ filename ...  ]

DESCRIPTION
       genccode reads each of the supplied filename and writes out a C file containing a  compilable
       definition  of the data in the data file.  The C file name is made by taking the base name of
       the data filename, replacing dots by underscores, and adding a .c file extension.

       If the -a option is used, platform specific assembly code is generated  instead  of  C  code.
       Most C compilers will accept both C and assembly files.  Instead of writing a filename with a
       .c file extension, a filename with a .s will be written instead.

       If genccode is called with no filename it terminates gracefully.

OPTIONS
       -h, -?, --help
              Print help about usage and exit.

       -a, --assembly name
              Output assembly code instead of C code.  Use -h to see the list of available types  of
              assembly to generate and to specify for this option.

       -d, --destdir destination
              Set  the  destination  directory to destination.  The default destination directory is
              the current directory.

       -n, --name name
              Set the data name to name instead of the default. This name is also used as  the  base
              name  of  the output. The default name is made of the icudt prefix, followed by a two-
              digit version number corresponding to the current version of the ICU  release,  and  a
              single letter indicating the endianness of the data (the letter b indicated big endian
              data, and the letter l indicates little endian ones).

       -f, --filename name
              Normally, an ICU data file such as mydata.icu will be turned into mydata_icu.c and my‐
              data_icu.o.   However,  if this parameter was set to "somedata", the output files will
              be somedata.o and somedata.c, respectively.

       -e, --entrypoint name
              Set the data entry point (used for linking against the data in a shared library  form)
              to  name.  The default entry point name is made of the data (set by the -n, --name op‐
              tion) followed by an underscore and the type of the data (set by the  -t,  --type  op‐
              tion).
