dyncall - A Generic Dynamic FFI package
=======================================

dyncall is a low-level toolkit providing a portable abstraction for 
handling native code dynamically at run time.
It comprises three independent components, available as C libraries, namely:

 - 'dyncall' for making function calls,
 - 'dyncallback' or writing generic callback handlers, and
 - 'dynload' for loading code.

The package provides abstractions to the Application Binary Interface 
of various hardware platforms such as x86, AMD64, ARM32/64, PowerPC32/64,
MIPS32/64 and SPARC32/64.

Our releases are thoroughly tested across all supported platforms using a
flexible test suite.

A typical application for the use of dyncall is the back-end of a FFI 
(foreign function interface) for scripting languages to connect with 
the C/C++ world.

The binary footprint of the package is approx. 10-20 kb, depending on
the platform.
Besides the test suite already mentioned, comprehensive documentation is
available.


Building the libraries
----------------------

Prequisites: 
 - C compiler such as gcc, clang, sunpro or msvc.
 - Assembler such as gas (gnu/apple), fbe or masm.
 - Build system such as 'shell/make', cmake, nmake (windows) or mk (plan9).


Supported Architectures and ABIs:
---------------------------------

 - x86     32/64-bit  (cdecl, fastcall, stdcall, C++ this calls, syscalls, plan9)
 - ARM     AArch32/64 (32: ARM/Thumb mode, v4t-v7, oabi/eabi, soft/hardfloat ABIs; 64: AAPCS64)
 - MIPS    32/64-bit  (o32, n64, eabi)
 - PowerPC 32/64-bit  (32: Mac OS X, System V; 64: System V little and big endian ELF ABI)
 - Sparc   32/64-bit  (v7/8 and v9)

NOTE: Callback support is currently available on
      x86-32/64, arm32 softfloat ABIs, arm64, PPC64 and PPC32 Linux/OS X.
