Segher, Will: Bill asked that I refresh thes 128-bit integer patch set and get it reposted. I have rebased the patches onto the latest mainline respository. I have also retested the patches on Power 8 BE, Power 9 LE and Power 10 LE hardware.
A request has been made last week to change the functionality of the 128-bit sign extension builtins. I pulled the support for these builtins out of the previous patch 2 and 3 and moved to a single last patch. That leaves five of the six patches ready for review. I will update and post the last, sixth, patch later when we have full agreement on what the new functionality will be. The following five patches have minor fixes to the builtin descriptions, typo fixes, etc. from the previous iteration. The patch series numbers have changed. Carl Love
