  "message": "[fuzz] Use a cache for IR modules in WGSL fuzzer\n\nThe WGSL fuzzer also runs the IR fuzzing passes via an adaptor. As-is\nthis adaptor requires re-lowering of the WGSL to IR per pass, which\ncan cause significant performance issues.\n\nThis change, if the IR binary format is available, caches the IR\nmodule as a protobuf and re-decodes it per pass, which is\nsignificantly faster (~3x for the timeout case I was looking at). The\nIR module cannot be cache\u0027d/cloned directly, so this re-decoding\npattern is the samething the IR natively does.\n\nIf the IR binary format is not available the fuzzer falls back\ngracefully to the existing lower per pass behaviour.\n\nFixes: 561406003\nChange-Id: I85bd9ab6530245ee24cfa3d43670924170420f96\nReviewed-on: https://dawn-review.googlesource.com/c/dawn/+/341835\nReviewed-by: James Price \u003cjrprice@google.com\u003e\nCommit-Queue: Ryan Harrison \u003crharrison@chromium.org\u003e\nAuto-Submit: Ryan Harrison \u003crharrison@chromium.org\u003e\nCommit-Queue: James Price \u003cjrprice@google.com\u003e\n",
