  "message": "Vulkan: Direct SPIR-V Gen: Support the precise keyword\n\nThe precise keyword is different in GLSL in that it defines what\narithmetic operations _that have led to the value being assigned to a\nvariable_ should be done precisely (i.e. not \"contracted\").\n\nA tree traverser is implemented that detects precise access chains and\napplies precise-ness to the right hand side of assignment expressions to\nsaid access chains.  This is only done if the shader uses the precise\nkeyword in the first place.  The algorithm for this is inspired by the\nimplementation in glslang.\n\nThis change additionally:\n\n- Fixes parser to allow precise on function parameters\n- Fixes GLSL code generation to output precise on struct members and\n  function parameters.\n\nBug: angleproject:4889\nChange-Id: Ie3808c3c8c08da308e88af20f5f90379d9d14d47\nReviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/3056369\nReviewed-by: Tim Van Patten \u003ctimvp@google.com\u003e\nReviewed-by: Jamie Madill \u003cjmadill@chromium.org\u003e\nCommit-Queue: Shahbaz Youssefi \u003csyoussefi@chromium.org\u003e\n",
