1535348 - Implement Group-rooted Shape Trees under a preference

Status: RESOLVED INVALID

(Core :: JavaScript Engine, enhancement, P2)

Description

[Matthew Gaudet (he/him) [:mgaudet]]

It should be possible to root our shape trees under groups under a preference to allow us to further investigate the possibility of going down that road in Shypes.

An initial version of this would regress memory when enabled by duplicating shapes without saving memory by removing the group pointer from objects, but it would allow us to evaluate other aspects of the system like performance (though, we'd have to be sensitive to the higher memory usage too)

For whoever starts looking at this, I think InitialShapeEntry is going to be of particular interest to you.

Closing this since groups no longer exists.
