This should allow us to keep pace with updating LLVM versions.\r\n\r\nThere are still two test suites that fail for specific reasons:\r\n-- ffi: We don't have GPU ffi support\r\n-- strings: String intrinsics are not implemented for the GPU yet\r\n\r\nWe also still do not generate reasonable GPU code for matrix multiplication, since the emitted IR is designed for serial execution."},"comment":{"url":"https://api.github.com/repos/simit-lang/simit/issues/comments/244850274","html_url":"https://github.com/simit-lang/simit/pull/47#issuecomment-244850274","issue_url":"https://api.github.com/repos/simit-lang/simit/issues/47","id":244850274,"user":{"login":"gkanwar","id":1031540,"avatar_url":"https://avatars.githubusercontent.com/u/1031540?v=3","gravatar_id":"","url":"https://api.github.com/users/gkanwar","html_url":"https://github.com/gkanwar","followers_url":"https://api.github.com/users/gkanwar/followers","following_url":"https://api.github.com/users/gkanwar/following{/other_user}","gists_url":"https://api.github.com/users/gkanwar/gists{/gist_id}","starred_url":"https://api.github.com/users/gkanwar/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/gkanwar/subscriptions","organizations_url":"https://api.github.com/users/gkanwar/orgs","repos_url":"https://api.github.com/users/gkanwar/repos","events_url":"https://api.github.com/users/gkanwar/events{/privacy}","received_events_url":"https://api.github.com/users/gkanwar/received_events","type":"User","site_admin":false},"created_at":"2016-09-06T05:01:07Z","updated_at":"2016-09-06T05:01:07Z","body":"Updated the builders, but looks like the Jenkins instance is out of hard drive space.
