It's not particularly about thie PR but Just curious, is there a reason we have different names for Op and BinaryConsts, such as ExtractLaneSVecI18x16 vs. I8x16ExtractLaneS?
There was a problem hiding this comment.
The BinaryConsts exactly mirror the underlying instruction naming with . and _ removed and the name CamelCased, but the Binaryen Op names are shuffled around to put the operation first and the relevant types later. This name change is meant to increase clarity by emphasizing the operation over the types, but it can also make the types clearer in conversion ops by inserting To into the op name, as in DotSVecI16x8ToVecI32x4.
