Update: I have successfully ported RISU to Sparc64, Solaris and Linux. There is a limitation in that I cannot find how to extract %gsr from the signal frame, which is unfortunate, but I can work around that for now. I have added descriptions of VIS1 instructions to RISU, and it turns out we have failures relative to a Sparc M8. I have not yet analyzed these failures, but it proves the effort was not wasted. :-) I'll clean up these patches and post them here when I next get some downtime. r~
