This caused minor\r\nproblems for the coming CUDA backend and major issues for the coming\r\nVulkan backend.  With the kernels written in the ImpCode.Kernels\r\nrepresentation, these backends can now simply use their general code\r\ngenerators.  Transposes are no longer magical (after ImpGen.Kernels).\r\n\r\nWe still have the same four versions that we used to.  In the short\r\nterm, the transpose block size is now hardcoded, but that will be\r\nfixed eventually.\r\n\r\nPerformance is supposed to be unaffected, but transposing byte arrays\r\nis inexplicably a bit slower.","created_at":"2018-12-17T20:03:32Z","updated_at":"2018-12-17T20:03:32Z","closed_at":null,"merged_at":null,"merge_commit_sha":null,"assignee":null,"assignees":[],"requested_reviewers":[],"requested_teams":[],"labels":[],"milestone":null,"commits_url":"https://api.github.com/repos/diku-dk/futhark/pulls/684/commits","review_comments_url":"https://api.github.com/repos/diku-dk/futhark/pulls/684/comments","review_comment_url":"https://api.github.com/repos/diku-dk/futhark/pulls/comments{/number}","comments_url":"https://api.github.com/repos/diku-dk/futhark/issues/684/comments","statuses_url":"https://api.github.com/repos/diku-dk/futhark/statuses/6332c6eb57b93647da7b5fff60567b1f2266d6d9","head":{"label":"diku-dk:impcode-transpose","ref":"impcode-transpose","sha":"6332c6eb57b93647da7b5fff60567b1f2266d6d9","user":{"login":"diku-dk","id":29549894,"node_id":"MDEyOk9yZ2FuaXphdGlvbjI5NTQ5ODk0","avatar_url":"https://avatars2.githubusercontent.com/u/29549894?v=4","gravatar_id":"","url":"https://api.github.com/users/diku-dk","html_url":"https://github.com/diku-dk","followers_url":"https://api.github.com/users/diku-dk/followers","following_url":"https://api.github.com/users/diku-dk/following{/other_user}","gists_url":"https://api.github.com/users/diku-dk/gists{/gist_id}","starred_url":"https://api.github.com/users/diku-dk/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/diku-dk/subscriptions","organizations_url":"https://api.github.com/users/diku-dk/orgs","repos_url":"https://api.github.com/users/diku-dk/repos","events_url":"https://api.github.com/users/diku-dk/events{/privacy}","received_events_url":"https://api.github.com/users/diku-dk/received_events","type":"Organization","site_admin":false},"repo":{"id":7960131,"node_id":"MDEwOlJlcG9zaXRvcnk3OTYwMTMx","name":"futhark","full_name":"diku-dk/futhark","private":false,"owner":{"login":"diku-dk","id":29549894,"node_id":"MDEyOk9yZ2FuaXphdGlvbjI5NTQ5ODk0","avatar_url":"https://avatars2.githubusercontent.com/u/29549894?v=4","gravatar_id":"","url":"https://api.github.com/users/diku-dk","html_url":"https://github.com/diku-dk","followers_url":"https://api.github.com/users/diku-dk/followers","following_url":"https://api.github.com/users/diku-dk/following{/other_user}","gists_url":"https://api.github.com/users/diku-dk/gists{/gist_id}","starred_url":"https://api.github.com/users/diku-dk/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/diku-dk/subscriptions","organizations_url":"https://api.github.com/users/diku-dk/orgs","repos_url":"https://api.github.com/users/diku-dk/repos","events_url":"https://api.github.com/users/diku-dk/events{/privacy}","received_events_url":"https://api.github.com/users/diku-dk/received_events","type":"Organization","site_admin":false},"html_url":"https://github.com/diku-dk/futhark","description":":boom::computer::boom:
