pure nothrow bool tooCostly(int cost);

Determine if too expensive to inline.

Parameters:

int cost

cost of inlining

Returns:

true if too costly

int inlineCostExpression(Expression e);

Determine cost of inlining Expression

Parameters:

Expression e

Expression to determine cost of

Returns:

cost of inlining e

int inlineCostFunction(FuncDeclaration fd, bool hasthis, bool hdrscan);

Determine cost of inlining function

Parameters:

FuncDeclaration fd	function to determine cost of
bool hasthis	if the function call has explicit 'this' expression
bool hdrscan	if generating a header file

Returns:

cost of inlining fd

AggregateDeclaration isInlinableNestedAggregate(DeclarationExp e);

Indicates if a nested aggregate prevents or not a function to be inlined. It's used to compute the cost but also to avoid a copy of the aggregate while the inliner processes.

Parameters:

DeclarationExp e

the declaration expression that may represent an aggregate.

Returns:

null if e is not an aggregate or if it is an aggregate that doesn't permit inlining, and the aggregate otherwise.
