  "message": "debug/gocore: handle 1.11 sparse heaps\n\nGo 1.11 changed (will change?) the Go heap.  Instead of a single\narena, there will be potentially multiple arenas.\n\nChange the way we do address-\u003eobject lookups to handle multiple,\nnot necessarily near each other, arenas.  The major change is to\nUse a page table instead of an array to keep HeapInfo structures.\n\nAlso move ptr/nonptr bits into HeapInfo, as they are recorded\ndifferently in 1.11.  It\u0027s a bit tricky because a heapInfo needs\ndifferent numbers of ptr/nonptr bits for 32 and 64 bit inferiors.\n\nI\u0027ll add a 1.11 test when 1.11 ships. A tip-compiled test passes\nwith this CL, but I don\u0027t want to check that in.\n\nChange-Id: I5b32fc4aaa88db137a23df2b4592eaba8a3f1fcc\nReviewed-on: https://go-review.googlesource.com/100059\nReviewed-by: Austin Clements \u003caustin@google.com\u003e\n",
