The function is doing something unsafe, so mark it as unsafe.

The function is calling @system function f, so mark it as unsafe.

setGC

The function calls non-@nogc function f, mark it as not nogc.

setThrow

setThrowCall
void setThrowCall(Loc loc, FuncDeclaration f)

isReturnIsolated
bool isReturnIsolated()

See if pointers from function parameters, mutable globals, or uplevel functions could leak into return value.

isTypeIsolated
bool isTypeIsolated(Type t)
bool isTypeIsolated(Type t, StringTable!Type parentTypes)

See if pointers from function parameters, mutable globals, or uplevel functions could leak into type t.

isNested
bool isNested()

Determine if function needs a static frame pointer.

isThis
inout(AggregateDeclaration) isThis()

Determine if function is a non-static member function that has an implicit 'this' expression.

isUnique
bool isUnique()
checkNestedReference
bool checkNestedReference(Scope* sc, Loc loc)

In the current function, we are calling 'this' function. 1. Check to see if the current function can call 'this' function, issue error if not. 2. If the current function is not the parent of 'this' function, then add the current function to the list of siblings of 'this' function. 3. If the current function is a literal, and it's accessing an uplevel scope, then mark it as a delegate. Returns true if error occurs.

needsClosure
bool needsClosure()

Look at all the variables in this function that are referenced by nested functions, and determine if a closure needs to be created for them.

checkClosure
bool checkClosure()

Check that the function contains any closure. If it's @nogc, report suitable errors. This is mostly consistent with FuncDeclaration::needsClosure().

hasNestedFrameRefs
bool hasNestedFrameRefs()

Determine if function's variables are referenced by a function nested within it.

buildResultVar
void buildResultVar(Scope* sc, Type tret)

Declare result variable lazily.

mergeFrequire
Statement mergeFrequire(Statement sf, Expressions* params)

Merge into this function the 'in' contracts of all it overrides. 'in's are OR'd together, i.e. only one of them needs to pass.

mergeFrequireInclusivePreview
Statement mergeFrequireInclusivePreview(Statement sf, Expressions* params)

Merge into this function the 'in' contracts of all it overrides.

needsFensure
bool needsFensure(FuncDeclaration fd)
