pointers, depending on the element types. All the discussion below
about Go pointers applies not just to pointer types, but also to other
types that include Go pointers.

All Go pointers passed to C must point to pinned Go memory. Go pointers
passed as function arguments to C functions have the memory they point to
implicitly pinned for the duration of the call. Go memory reachable from

	//	min <  ind <  max    [if flags == indVarMinExc]
	//	min <= ind <= max    [if flags == indVarMaxInc]
	//	min <  ind <= max    [if flags == indVarMinExc|indVarMaxInc]
}

// parseIndVar checks whether the SSA value passed as argument is a valid induction
// variable, and, if so, extracts:
//   - the minimum bound
//   - the increment value
//   - the "next" value (SSA value that is Phi'd into the induction variable every loop)
//

// has an ODCLFUNC (and a matching ONAME) representing the compiled
// underlying form of the closure, which accesses the captured variables
// using a special data structure passed in a register.
//
// A method declaration is represented like functions, except f.Sym
// will be the qualified method name (e.g., "T.m").
//
// A method expression (T.M) is represented as an OMETHEXPR node,

// fall broadly into three categories:
//
// 1) adjustments based solely on the callsite context (ex: call
// appears on panic path)
//
// 2) adjustments that take into account specific interesting values
// passed at a call site (ex: passing a constant that could result in
// cprop/deadcode in the caller)
//
// 3) adjustments that take into account values returned from the call

// than a full scheduling as done above.
// Note that simple dependency order won't work: there is no
// dependency between NilChecks and values like IsNonNil.
// Auxiliary data structures are passed in as arguments, so
// that they can be allocated in the caller and be reused.
// This function takes care of reset them.
func storeOrder(values []*Value, sset *sparseSet, storeNumber []int32) []*Value {

will emit debug output for all functions, and other passes will
only emit debug output for functions that match the current
GOSSAFUNC value.

Multiple flags can be passed at once, by separating them with
commas. For example:

    -d=ssa/check/on,ssa/all/time
