1864090 - Expand js::debug::GetMarkInfo() to accept arbitrary pointers

Status: RESOLVED FIXED

(Core :: JavaScript: GC, enhancement)

Description

[Steve Fink [:sfink] [:s:]]

I find it very convenient to call js::debug::GetMarkInfo on random Cell*s to see whether they're nursery or tenured and, if tenured, how they are marked.

With string buffers in the nursery, it would also be nice if it could accept an arbitrary pointer and say whether it was in the nursery or not. (If not, it is probably malloced, but could be static data or the stack or lots of other things.)
