New issue 2320: PowerPC VSX support
The goal is to enhance the backend to support PowerPC SIMD unit. Ultimately this will enhance the execution speed of micro NumPy.
Only the most recent ISA will be supported. A hard requirement for the time being is the support for unaligned loads/stores.
What to expect: As soon as enough time is spent in the optimized (vectorized) code, one can measure faster execution. For a micro benchmark stressing the implementation it
would be a factor of 1.5x-2.0x speedup for e.g. float (64bit) addition/multiplication.
A benchmark run will evaluate the implementation on ppc and compare it to x86.
