I have written quite a bit of SPE code. The primary issue is that the SPE processor could only read/write to 256kB localized memory (without doing a DMA). So literally object orientated code doesnt even work (because of VTables). The c/c++ model is not designed for this type of architecture. Yes there were also limitations like vector only registers and memory alignment but the biggest issue was the local memory.
