Hello all, I'm currently working on PowerPC port of Mono which utilizes AltiVec SIMD instructions. During the development I've encountered an alignment problem:
As far as I understood from running Mono's JIT, stack-allocated Mono.Simd.Vector* types are always aligned by 16 byte bound, but global ones aren't (such as static class members). This is not a problem for SSE which has unaligned load/stores but AltiVec doesn't have them. Instead of implementing misaligned loads/stores for AltiVec I think it's better to force alignment in global variables, as it done in the case of stack. Can somebody help me with that (e.g. point at relevant places in 'mini-ppc.c')? Thanks, Sergei Dyshel
