Updated:
Mir is LLVM-Accelerated Generic Numerical Library for Science and 
Machine Learning. It requires LDC (LLVM D Compiler) for 
compilation. Mir GLAS (Generic Linear Algebra Subprograms) has a 
single generic kernel for all CPU targets, all floating point 
types, and all complex types. It is written completely in D, 
without any assembler blocks. In addition, Mir GLAS Level 3 
kernels are not unrolled and produce tiny binary code, so they 
put less pressure on the instruction cache in large applications.
