--- Comment #7 from Carl Love <c...@us.ibm.com> --- Created attachment 108069 --> https://bugs.kde.org/attachment.cgi?id=108069&action=edit Use vperm Iop code with minor modifications to implement the xxperm and xxpermr instructions The xxperm instructions does the same permute as the vperm instruction. The difference is the xxperm instruction works on the VSX register file and hte vperm works on the VR register file. The vperm instruction has three input registers and the xxperm has two input registers and then uses the output register as an additional input register. Basically, you can use the vperm instruction to emulate the xxperm with some register renaming. The attached patch just takes the existing vperm Iop code and tweeks it to do the xxperm and xxpermr instructions. This only generates a few Iops rather then the massive amount of iops as the previous implementation. -- You are receiving this mail because: You are watching all bug changes.
