  "message": "bridge: mark write barrier functions GC leaf\n\nSet \"gc-leaf-function\" attribute for the write barrier\nfunctions. The backend understands this attribute and does not\ntreats the call sites as statepoints.\n(llvm/lib/Transforms/Utils/Local.cpp, callsGCLeafFunction)\nThis makes the write barriers cheaper (avoid spillings), and\nalso makes it easier to remove write barriers for stack writes\n(not in this CL).\n\nChange-Id: Id5b97275b99c8717d3b9c095231ee0f6e09fe00c\nReviewed-on: https://go-review.googlesource.com/c/156558\nReviewed-by: Than McIntosh \u003cthanm@google.com\u003e\n",
