[LLVMdev] [Discussion] Portable SIMD programming using LLVM?
...is model.
*Background*
Almost modern processor families support SIMD instruction sets but the
instruction set designs for each platform have different combinations of
operations. The portable SIMD here is to make an uniform system of SIMD
operations at all power-of-2 field widths.
For example, for simd_add on SSE2, I want to have all the following
operations supported, simd<2^x>::add(a, b) for
2<=2^x<=register_size(register_size equals 128 in SSE2). However, SSE2 only
supports simd_add on field widths of 8, 16, 32, or 64. Hence, simulation for
simd_add on field widths of 2, 4 and 128 is n...
