Building

On Windows (user-mode), depending on your target platform, one of the following toolchains is required;

On Windows (kernel-mode), the following toolchain is required;

On Linux, the following toolchain is required;

  • gcc 4.1.0 or later and GNUmake 3.81

For documentation, see the building guide.

Using

Once built, there is a single header file, /inc/liblfds600.h and a single library file /bin/liblfds.*. The suffix of the library file varies by platform and by the type of library you have chosen to build (static or dynamic).

Testing and Benchmarking

The library comes with a command line test and benchmark program. This program requires threads. As such, it is only suitable for platforms providing thread support and which can execute a command line binary. Currently this means the test and benchmark program works for all platforms except the Windows Kernel.

For documentation, see the testing and benchmarking guide.

Porting

Both the test program and liblfds provide an abstraction layer which acts to mask platform differences. Porting is the act of implementing on your platform the functions which make up the abstraction layers. You do not need to port the test program to port liblfds, but obviously it is recommended, so you can test your port.

To support liblfds, your platform must support either contigious double-word compare-and-swap (e.g. x86/x64) or contigious double-word load-link/conditional-store where normal loads cannot occur inside the LL/CS pair (e.g. ARM) or single word load-link/conditional-store where normal loads can occur inside the LL/CS pair.

This requirement excludes the IA64, MIPS, PowerPC and SPARC platforms.

For documentation, see the porting guide.
