  "message": "Fix float-to-half conversion\n\nThe Reactor code in floatToHalfBits() did not match the reference\nimplementation of the sw::half type, leading to failures in dEQP tests\nwhich are enabled by the shaderStorageImageExtendedFormats feature.\n\nThe previous code was based on https://gist.github.com/rygorous/2156668.\nIt doesn\u0027t round to nearest even in case of a tie, but that\u0027s not\ndemanded by Vulkan. It merits a closer look to see whether there was a\nbug, or whether dEQP-VK is too strict. Dawn also found the previous\nimplementation to not handle infinity correctly, so a bug seems likely.\n\nIn any case, it\u0027s good to use a reference implementation for now, and\nlook for optimization opportunities later.\n\nBug: b/147900455\nBug: swiftshader:147\nTests: dEQP-VK.image.format_reinterpret.buffer.*_b10g11r11_ufloat_pack32\nChange-Id: Id817a012ff38af814907c2de2914ec24565622f3\nReviewed-on: https://swiftshader-review.googlesource.com/c/SwiftShader/+/46148\nPresubmit-Ready: Nicolas Capens \u003cnicolascapens@google.com\u003e\nKokoro-Result: kokoro \u003cnoreply+kokoro@google.com\u003e\nTested-by: Nicolas Capens \u003cnicolascapens@google.com\u003e\nReviewed-by: Antonio Maiorano \u003camaiorano@google.com\u003e\n",
