Message : Translator: Generate Ops for all built-in functions EOpCallBuiltInFunction is removed in this change, as well as the "op": "auto" property in builtin_function_declarations.txt. Instead, gen_builtin_symbols.py automatically generates Ops for every built-in function and generates the TOperator enum accordingly. This simplifies SPIR-V code generation by allowing switches to be used on operators instead of string comparisons.
