The dyncall library project provides a clean and portable C interface to dynamically issue foreign function calls using small call kernels written in assembly. Instead of providing code for every bridged function call, which unnecessarily results in code bloat, only a modest number of instructions are used to invoke all calls. License: BSD License (revised) Changes:
Two new ports were added for ARM THUMB mode and PowerPC 32-bit System V ABI. The System V port has been tested on Linux, but the *BSDs are currently untested. A bug was fixed for cygwin/GNU as a tool chain. Additions and improvements were made in the test suites. Minor cosmetic changes and documentation updates were made.
GENCCODE(8) ICU 50.1.2 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 let-
ter 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).
