  "message": "spirv-opt: fix adce when ns debug info present (#6217) (#6420)\n\nThis PR fixes two problems in ADCE while processing NonSemantic debug\ninfo. The first change is to treat DebugDeclare similarly to DebugValue:\nif a Variable is dead, replace it with OpUndef. This mirrors the\ntreatment of DebugValue for the Value operand. This fixes\nhttps://github.com/KhronosGroup/SPIRV-Tools/issues/6217.\n\nNext, we declare all DebugLocalVariable, DebugExpression, and\nDebugOperation instructions to be live at initialization since there is\nno reason to ever kill them. They do not have variables that, if\ndeclared live, would have follow-on impact to DCE. This fixes\nhttps://github.com/microsoft/DirectXShaderCompiler/issues/7874.",
