Analog Devices Blackfin back-end.
Generate code for the Blackfin family of DSPs from Analog Devices:
http://www.analog.com/en/embedded-processing-dsp/blackfin/processors/index.html
We aim to be compatible with the exsisting GNU toolchain found at:
http://blackfin.uclinux.org/gf/project/toolchain
The back-end is experimental.
