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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77897 91177308-0d34-0410-b5e6-96231b3b80d8
