struct CtorFlow;

Primitive flow analysis for constructors

CSX callSuper;

state of calling other constructors

CSX[] fieldinit;

state of field initializations

CtorFlow clone();

Create a deep copy of this

Returns:

a copy

pure nothrow void orCSX(CSX csx);

Set CSX bits in flow analysis state

Parameters:

CSX csx bits to set

pure nothrow void OR(ref const CtorFlow ctorflow);

OR CSX bits to this

Parameters:

CtorFlow ctorflow bits to OR in

pure nothrow bool mergeCallSuper(ref CSX a, const CSX b);

Merge b flow analysis results into a.

Parameters:

CSX `a`	the path to merge `b` into
CSX `b`	the other path

Returns:

false means one of the paths skips construction

pure nothrow bool mergeFieldInit(ref CSX a, const CSX b);

Merge b flow analysis results into a.

Parameters:

CSX `a`	the path to merge `b` into
CSX `b`	the other path

Returns:

false means either a or b skips initialization
