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.
"-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 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).
