  Hash : 56db3789
  Message : Use flat arrays instead of switches for function lookups Current implementation of built in function lookup uses autogenerated switch statements. Instead, use the perfect hash mapping to have the lookup use arrays instead. This will improve runtime performance. Bug: angleproject:3805 Change-Id: I6d0ba62d79abd53a7fe818fe675282800781f256 Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/1756883 Commit-Queue: Clemen Deng <clemendeng@google.com> Reviewed-by: Geoff Lang <geofflang@chromium.org>

• // The format of this file:
  //   C++ style single-line comments are supported.
  //   Leading whitespace is only for formatting and doesn't have semantic meaning.
  //
  //   Grouping:
  //   Groups of functions are denoted by "GROUP BEGIN" and "GROUP END". Groups can be nested.
  //   Groups can have metadata related to the group itself. This is given at the end of the GROUP
  //   BEGIN line in JSON object format.
  //   Example:
  //     GROUP BEGIN <group name> {"shader_type": "FRAGMENT"}
  //     GROUP END <group name>
  //
  //   Defaults:
  //   Default metadata for functions can be set with "DEFAULT METADATA" followed by metadata in JSON
  //   object format. The metadata is applied to all following functions regardless of grouping until
  //   another "DEFAULT METADATA" line is encountered, or until the end of a top-level group.
  //   Example:
  //     DEFAULT METADATA {"op": "CallBuiltInFunction"}
  //
  //   Supported function metadata properties are:
  //     "essl_level"
  //         string, one of COMMON_BUILTINS, ESSL1_BUILTINS, ESSL3_BUILTINS and ESSL3_1_BUILTINS.
  //     "glsl_level"
  //         string, one of COMMON_BUILTINS, COMMON_BUILTINS, GLSL1_2_BUILTINS, GLSL1_3_BUILTINS,
  //         GLSL1_4_BUILTINS, GLSL1_5_BUILTINS, GLSL3_3_BUILTINS, GLSL4_BUILTINS, GLSL4_1_BUILTINS,
  //         GLSL4_2_BUILTINS, GLSL4_3_BUILTINS, GLSL4_4_BUILTINS, GLSL4_5_BUILTINS, and
  //         GLSL4_6_BUILTINS.
  //     "op"
  //         string, either EOp code or "auto", in which case the op is derived from the function
  //         name.
  //     "suffix"
  //         string, suffix that is used to disambiguate C++ variable names created based on the
  //         function name from C++ keywords, or disambiguate two functions with the same name.
  //     "essl_extension"
  //         string, ESSL extension where the function is defined.
  //     "glsl_extension"
  //         string, GLSL extension where the function is defined.
  //     "hasSideEffects"
  //         boolean, can be used to mark a function as having side effects even if it has op other
  //         than CallBuiltInFunction and it doesn't have out parameters. In case the op is
  //         CallBuiltInFunction or the function has out parameters it is automatically treated as
  //         having side effects.
  //
  //   Function declarations:
  //   Lines that declare functions are in a similar format as in the GLSL spec:
  //     <return type> <function name>(<param type>, ...);
  //   Parameter types can have "out" or "inout" qualifiers.
