+// The blocks of the flow graph are designated with letters A

+// block) The specification of a flow graph is a comma-
+// separated list of block successor words, for blocks ordered
+// A, B, C etc, where each block except Z has one or two
+// successors, and any block except A can be a target. Within
+// the generated code, each block with two successors includes
+// a conditional testing x & 1 != 0 (x is the input parameter
+// to the generated function) and also unconditionally shifts x
+// right by one, so that different inputs generate different
+// execution paths, including loops. Every block inverts a
+// global binary to ensure it is not empty. For a flow graph
+// with J words (J+1 blocks), a J-1 bit serial number specifies
+// which blocks (not including A and Z) include an increment of
+// the return variable y by increasing powers of 10, and a
+// different version of the test function is created for each
+// of the 2-to-the-(J-1) serial numbers.
+
+// For each generated function a compact summary is also
+// created so that the generated function can be simulated
+// with a simple interpreter to sanity check the behavior of
+// the compiled code.

+// function, which is invoked to zero out ambiguously live portions of
+// the stack frame in certain specific circumstances.
+//
+// In the current compiler implementation, for zerorange to be
+// invoked, we need to have an ambiguously live variable that needs
+// zeroing. One way to trigger this is to have a function with an
+// open-coded defer, where the opendefer function has an argument that
+// contains a pointer (this is what's used below).
+//
+// At the moment this test doesn't do any specific checking for
+// code sequence, or verification that things were properly set to zero,
+// this seems as though it would be too tricky and would result
+// in a "brittle" test.
+//
+// The small/medium/large scenarios below are inspired by the amd64
+// implementation of zerorange, which generates different code
+// depending on the size of the thing that needs to be zeroed out
+// (I've verified at the time of the writing of this test that it
+// exercises the various cases).
