I think you meant #329 instead of 319, right? |
SIMD functions that take a lane index (extractLane, replaceLane, swizzle, shuffle) should use ToNumber() to coerce the lane index to a number before checking that the index is an integer in range. This behavior corresponds to the SIMDToLane() function in the SIMD.js specification. This fixes issues #329 and #237.

Oops, you are right. Fixed. |

There was a problem hiding this comment.
Maybe implement simdCoerceLaneIndex() using simdCoerceIndex(), just to avoid a little code duplication. It shouldn't matter that the index != Math.floor() check fails before the bounds check, I think.
