Folks, Currently Divya is doing some more work on missing instructions for s390x (e.g. stck, translate etc.). I will open bugzillas for these when the patches are ready. There are some crypto instructions (hashing, DES, etc.) which we also want to implement. These instruction get a parameter block two memory fields and a length. Since crypto cannot be modeled in an efficient way we first thought that a dirty helper might be the right solution, but there are some problems: - Dirty can only have one memory area - The length field (mSize) cannot be an IRTemp What might be a good approach to tackle these instruction? Can we enhance Dirty helpers to accept multiple memory areas with dynamic length fields (this would require changes in most tools, I guess)? Any better ideas? Christian |
