Bug 39144 – Implement Float64Array

• Component: WebGL
• Status: RESOLVED FIXED

[Kenneth Russell]

The implementation of the TypedArray specification in WebKit, which originally only contained those types relevant to WebGL, needs Int64Array, Uint64Array and DoubleArray in order to be complete.

[Chris Marrin]

If we add those, we should probably also add BoolArray for completeness

[Oliver Hunt]

why does it need int/uint64? these types cannot be represented in JS at all?

Oops, I should have checked the spec. You're right, those aren't present. Revised the summary to indicate only DoubleArray needs to be implemented.

[Kenneth Russell]

The TypedArray spec has been modified to call this Float64Array rather than DoubleArray. Updated the summary.

wrong copyright header: should be 2-clause, etc (like the other files in this patch)

Actually Apple is correct. This code was copied from JSFloat32ArrayCustom.cpp in the same directory.
