            Bug ID: 188517
           Summary: [WHLSL] Reimplement the parser with a parser generator
           Product: WebKit
           Version: Other
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebGPU
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: tdenney at apple.com

The current hand-written recursive-descent parser is relatively slow and is the main bottleneck of the `prepare` function. The parser should be rewritten using a tool that produces more efficient code, such as https://github.com/antlr/antlr4.
