  "message": "cmd/compile: add anchored version of SP\n\nThe SPanchored opcode is identical to SP, except that it takes a memory\nargument so that it (and more importantly, anything that uses it)\nmust be scheduled at or after that memory argument.\n\nThis opcode ensures that a LEAQ of a variable gets scheduled after the\ncorresponding VARDEF for that variable.\n\nThis may lead to less CSE of LEAQ operations. The effect is very small.\nThe go binary is only 80 bytes bigger after this CL. Usually LEAQs get\nfolded into load/store operations, so the effect is only for pointerful\ntypes, large enough to need a duffzero, and have their address passed\nsomewhere. Even then, usually the CSEd LEAQs will be un-CSEd because\nthe two uses are on different sides of a function call and the LEAQ\nends up being rematerialized at the second use anyway.\n\nChange-Id: Ib893562cd05369b91dd563b48fb83f5250950293\nReviewed-on: https://go-review.googlesource.com/c/go/+/452916\nTryBot-Result: Gopher Robot \u003cgobot@golang.org\u003e\nRun-TryBot: Keith Randall \u003ckhr@golang.org\u003e\nReviewed-by: Martin Möhrmann \u003cmoehrmann@google.com\u003e\nReviewed-by: Martin Möhrmann \u003cmartin@golang.org\u003e\nReviewed-by: Keith Randall \u003ckhr@google.com\u003e\n",
