One function interleaves its input (trunc_satub.vuh) and the\r\nother does not (pack_satub.vuh)\r\n\r\nThis patch also removes declaration of some intrinsics not use any\r\nlonger in hvx_128.ll\r\n\r\n* Make IR dump messages in HexagonOptimize.cpp consistent with those in CodeGen_Hexagon.cpp\r\n\r\n* fix clang-format complaints\r\n\r\n---------\r\n\r\nCo-authored-by: Steven Johnson <srj@google.com>","shortMessageHtmlLink":"[Hexagon] - Fix 8-bit unsigned saturating downcasts for HVX (<span class=\"issue-keyword tooltipped tooltipped-se\" aria-label=\"This commit closes issue #7806.\">Fixes</span> <a class=\"issue-link js-issue-link\" data-error-text=\"Failed to load title\" data-id=\"1865983520\" data-permission-text=\"Title is private\" data-url=\"https://github.com/halide/Halide/issues/7806\" data-hovercard-type=\"issue\" data-hovercard-url=\"/halide/Halide/issues/7806/hovercard\" href=\"https://github.com/halide/Halide/issues/7806\">ha…</a>"}}],"hasNextPage":false,"hasPreviousPage":false,"activityType":"all","actor":null,"timePeriod":"all","sort":"DESC","perPage":30,"cursor":"djE6ks8AAAADhBgmkQA","startCursor":null,"endCursor":null}},"title":"Activity · alinas/Halide"}
