Changed paths: M Source/WebGPU/WGSL/GlobalVariableRewriter.cpp A Source/WebGPU/WGSL/tests/valid/fuzz-127229681.wgsl Log Message: ----------- [WGSL] Pointers should not be unpacked https://bugs.webkit.org/show_bug.cgi?id=273894 rdar://127229681 Reviewed by Mike Wyrzykowski. The fuzzer found a crash due to the base of an index access being incorrectly unpacked when it was an address-of expression. We would always unpack unary expressions, since math operations should be performed on unpacked values, but for pointer operators (address-of and dereference) we do not need to force the operand to be unpacked. * Source/WebGPU/WGSL/GlobalVariableRewriter.cpp: (WGSL::RewriteGlobalVariables::visit): (WGSL::RewriteGlobalVariables::getPacking): * Source/WebGPU/WGSL/tests/valid/fuzz-127229681.wgsl: Added.
