Functions

Name	Description
`checkArrayLiteralEscape(sc, ae, gag)`	Array literal is going to be allocated on the GC heap. Check its elements to see if any would escape by going on the heap.
`checkAssignEscape(sc, e, gag)`	Given an AssignExp, determine if the lvalue will cause the contents of the rvalue to escape. Print error messages when these are detected. Infer 'scope' for the lvalue where possible, in order to eliminate the error.
`checkAssocArrayLiteralEscape(sc, ae, gag)`	Associative array literal is going to be allocated on the GC heap. Check its elements to see if any would escape by going on the heap.
`checkNewEscape(sc, e, gag)`	Detect cases where pointers to the stack can 'escape' the lifetime of the stack frame by being placed into a GC allocated object. Print error messages when these are detected.
`checkParamArgumentEscape(sc, fdc, par, arg, gag)`	Function parameter par is being initialized to arg, and par may escape. Detect if scoped values can escape this way. Print error messages when these are detected.
`checkReturnEscape(sc, e, gag)`	Detect cases where pointers to the stack can 'escape' the lifetime of the stack frame by returning 'e' by value. Print error messages when these are detected.
`checkReturnEscapeRef(sc, e, gag)`	Detect cases where returning 'e' by ref can result in a reference to the stack being returned. Print error messages when these are detected.
`checkThrowEscape(sc, e, gag)`	Detect cases where pointers to the stack can 'escape' the lifetime of the stack frame when throwing `e`. Print error messages when these are detected.
`findAllOuterAccessedVariables(fd, vars)`	Find all variables accessed by this delegate that are in functions enclosing it.
`notMaybeScope(v)`	Turn off STC.maybescope for variable `v`. This exists in order to find where STC.maybescope is getting turned off.
