The MicroBlaze is a highly configurable 32-bit soft-microprocessor for use on Xilinx FPGAs. For more information see: http://www.xilinx.com/tools/microblaze.htm http://en.wikipedia.org/wiki/MicroBlaze The current LLVM MicroBlaze backend generates assembly which can be compiled using the an appropriate binutils assembler. llvm-svn: 96969
