            Bug ID: 189755
           Summary: [WHLSL] Enum types with no zero value can’t be
                    zero-initialized
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebGPU
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: tdenney at apple.com

See EnumType.populateDefaultValue. Consider the enum type

enum A { B = 1, C = 2 }

Currently an A value will be initialized with zero, which isn’t a valid value of the enum. We need to specify this behavior, update the interpreter, and update the compiler.
