1024079 - Get JSOP_NAME in on the DOM game.

Status: RESOLVED WONTFIX

(Core :: JavaScript Engine: JIT, defect, P5)

Description

[Eric Faust [:efaust]]

We have a fastpath for accessess off the global on JSOP_GNAME, and bug 1022736 adds a patch to allow Ion ICs to do getter calls for props on the global found after walking the scope chain.

This would be improved further by having Ion fastpaths available for this case, so that we can avoid the ICs all together.

This comes in two stages. We need to ensure that BC can cache these getters, and then teach Ion that it should want to look for them. With any luck that will get us even faster in these cases.

Wontfix: Ion ICs have been replaced by CacheIR.
