From 000e2958f59a8d8e07f06e384546aa942d49b15f Mon Sep 17 00:00:00 2001 From: Tim Rowley Date: Thu, 7 Sep 2017 18:53:03 -0500 Subject: [PATCH] swr/rast: Fetch compile state changes Add InstanceStrideEnable field and rename InstanceDataStepRate to InstanceAdvancementState in INPUT_ELEMENT_DESC structure. Add stubs for handling InstanceStrideEnable in FetchJit::JitLoadVertices() and FetchJit::JitGatherVertices() and assert if they are triggered.
