GENCCODE(8)                 ICU 76.0.1 Manual                GENCCODE(8)

NAME         top

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

SYNOPSIS         top

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

DESCRIPTION         top

       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         top

       -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

       -f, --filename name
              Normally, an ICU data file such as will be
              turned into mydata_icu.c and mydata_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
              option) followed by an underscore and the type of the data
              (set by the -t, --type option).
