Hi Kit/Gareth Thanks for this work - I've been following all your changes to win64. Can't say I understand all of the vector ones. Be good to commit to trunk asap - tho' gather your are waiting for some Florian mods.
Just few qs - maybe these could be clarified in comments/example/tests 1) How does this work on amd processors that have vector stuff? 2)exactly which processors amd/intel have this stuff? 3) don't understand why this stuff doesn't work w/o mods on linux, which I think you say somewhere. Thanks again john PS assume you are on devel list tho' doing a reply to this email in gmail copies you and devel? Dohhhhh. On 7 February 2018 at 08:23, J.
