// The racewalk pass is currently handled in three parts.
//
// First, for flag_race, it inserts calls to racefuncenter and
// racefuncexit at the start and end (respectively) of each
// function. This is handled below.
//
// Second, during buildssa, it inserts appropriate instrumentation
// calls immediately before each memory load or store. This is handled
// by the (*state).instrument method in ssa.go, so here we just set
// the Func.InstrumentBody flag as needed. For background on why this
// is done during SSA construction rather than a separate SSA pass,
// see issue #19054.
//
// Third we remove calls to racefuncenter and racefuncexit, for leaf
// functions without instrumented operations. This is done as part of
// ssa opt pass via special rule.

// TODO(dvyukov): do not instrument initialization as writes:
// a := make([]int, 10)
