You can find the wasm.json files at "Source/JavaScriptCore/wasm/wasm.json" and "JSTests/wasm/wasm.json". Comment on attachment 365907 [details] Patch View in context: https://bugs.webkit.org/attachment.cgi?id=365907&action=review r=me with a few minor nits. > Source/JavaScriptCore/ChangeLog:8 > + Generalize the fix for f32.max from r243446 to all min and max float operations. nit: Also worth one sentence on what r243446 fixed. > Source/JavaScriptCore/wasm/WasmAirIRGenerator.cpp:572 > + enum MinOrMax { Min, Max }; nit: let's use `enum class`. > Source/JavaScriptCore/wasm/WasmAirIRGenerator.cpp:2792 > + auto isEqualOp = minOrMax == Max ? andOp : orOp; nit: this variable name is kind of a weird, since we're in the "isEqual" block, but this op isn't about equality. I'd vote for just inlining this in the append. > Source/JavaScriptCore/wasm/WasmAirIRGenerator.cpp:2798 > + auto moveOp = floatType == F32 ? MoveFloat : MoveDouble; nit: I'd just inline this below into the append. Also, this can just be: append(isLessThan, moveOpForValueType(floatType), ...) Created attachment 365980 [details]
