  "message": "runtime: change top-most return PC from goexit to goexit+PCQuantum\n\nIf you get a stack of PCs from Callers, it would be expected\nthat every PC is immediately after a call instruction, so to find\nthe line of the call, you look up the line for PC-1.\nCL 163550043 now explicitly documents that.\n\nThe most common exception to this is the top-most return PC\non the stack, which is the entry address of the runtime.goexit\nfunction. Subtracting 1 from that PC will end up in a different\nfunction entirely.\n\nTo remove this special case, make the top-most return PC\ngoexit+PCQuantum and then implement goexit in assembly\nso that the first instruction can be skipped.\n\nFixes #7690.\n\nLGTM\u003dr\nR\u003dr\nCC\u003dgolang-codereviews\nhttps://golang.org/cl/170720043\n",
